On the other hand, bold blues and greens often create a calming effect, which is why they are frequently used in bedrooms and bathrooms.
However, going bold is not without its risks! sheen Choosing a bright or unconventional color can sometimes overwhelm a space if not balanced correctly with other elements in the room. Its important to consider the size of the room and the amount of natural light it receives.

A very bright color in a small or dark room can make the space feel even smaller or more enclosed.
Another aspect to consider is the psychological effects of color. efficiency Color psychology is a field of study that's devoted to analyzing the emotional and behavioral effects produced by colors and color combinations. coveragewalls It suggests that while some colors can lift our spirits and improve our energy levels, others might lead to feelings of sadness or irritability. For instance, some studies have shown that while red can increase energy levels, it can also increase feelings of hostility or anger in some people.
From a practical standpoint, choosing a bold color can also be a commitment. Bold colors might not be as easy to paint over as more neutral ones, and they can also affect the resale value of your home. Potential buyers might be turned off by unusual color choices, viewing them as an additional expense to change after purchase.
On a brighter note, bold colors can also work wonders if used creatively! They can highlight architectural features, define spaces, and create a unique and memorable aesthetic. A bold accent wall, for instance, can add depth and interest to a room without overpowering it. palette And let's not forget, it can be a reflection of your personality and style, making your home feel truly yours.
In conclusion, when it comes to deciding whether or not to go bold with paint choices, its a balance of aesthetics, psychological impact, practicality, and personal taste.

Just remember to consider all the factors involved to make the most informed decision. Happy painting!
Paint is a material or mixture that, when applied to a solid material and allowed to dry, adds a film-like layer. As art, this is used to create an image or images known as a painting. Paint can be made in many colors and types. Most paints are either oil-based or water-based, and each has distinct characteristics.
Primitive forms of paint were used tens of thousands of years ago in cave paintings.[1][2]
Clean-up solvents are also different for water-based paint than oil-based paint.[3] Water-based paints and oil-based paints will cure differently based on the outside ambient temperature of the object being painted (such as a house).
Paint was used in some of the earliest known human artworks. Some cave paintings drawn with red or yellow ochre, hematite, manganese oxide, and charcoal may have been made by early Homo sapiens as long as 40,000 years ago.[4] Paint may be even older. In 2003 and 2004, South African archeologists reported finds in Blombos Cave of a 100,000-year-old human-made ochre-based mixture that could have been used like paint.[5][6] Further excavation in the same cave resulted in the 2011 report of a complete toolkit for grinding pigments and making a primitive paint-like substance.[6][7] The earliest applications of paint served purely ornamental purposes. Consequently, pigment lacking any adhesive agent—composed mainly of iron oxide was employed in prehistoric cave art around the 15,000s BC in parts of Asia.[8]
Interior walls at the 5,000-year-old Ness of Brodgar have been found to incorporate individual stones painted in yellows, reds, and oranges, using ochre pigment made of haematite mixed with animal fat, milk or eggs.[9][10]
Ancient colored walls at Dendera, Egypt, which were exposed for years to the elements, still possess their brilliant color, as vivid as when they were painted about 2,000 years ago. The Egyptians mixed their colors with a gummy substance and applied them separately from each other without any blending or mixture. They appear to have used six colors: white, black, blue, red, yellow, and green. They first covered the area entirely with white, then traced the design in black, leaving out the lights of the ground color. They used minium for red, generally of a dark tinge.[11]
The oldest known oil paintings are Buddhist murals created c. 650 AD. The works are located in cave-like rooms carved from the cliffs of Afghanistan's Bamiyan Valley, "using walnut and poppy seed oils."[12]Pliny mentions some painted ceilings in his day in the town of Ardea, which had been made before the foundation of Rome. After the lapse of so many centuries, he expressed great surprise and admiration at their freshness.
In the 13th century, oil was used to detail tempera paintings. In the 14th century, Cennino Cennini described a painting technique utilizing tempera painting covered by light layers of oil. The slow-drying properties of organic oils were commonly known to early European painters. However, the difficulty in acquiring and working the materials meant that they were rarely used (and indeed, the slow drying was seen as a disadvantage[13]). The paint was made with the yolk of eggs, and therefore, the substance would harden and adhere to the surface it was applied to. The pigment was made from plants, sand, and different soils. Most paints use either oil or water as a base (the diluent, solvent, or vehicle for the pigment).
The Flemish-trained or influenced Antonello da Messina, who Vasari wrongly credited with the introduction of oil paint to Italy,[14] does seem to have improved the formula by adding litharge, or lead (II) oxide. A still extant example of 17th-century house oil painting is Ham House in Surrey, England, where a primer was used along with several undercoats and an elaborate decorative overcoat; the pigment and oil mixture would have been ground into a paste with a mortar and pestle. The painters did the process by hand, which exposed them to lead poisoning due to the white-lead powder.
In 1718, Marshall Smith invented a "Machine or Engine for the Grinding of Colors" in England. It is not known precisely how it operated, but it was a device that dramatically increased the efficiency of pigment grinding. Soon, a company called Emerton and Manby was advertising exceptionally low-priced paints that had been ground with labor-saving technology:
Paint used every day: White paint on a wall in Suzdal, Russia
One Pound of Colour ground in a Horse-Mill will paint twelve Yards of Work, whereas Colour ground any other Way, will not do half that Quantity.
By the proper onset of the Industrial Revolution, in the mid-18th century, paint was being ground in steam-powered mills, and an alternative to lead-based pigments had been found in a white derivative of zinc oxide. Interior house painting increasingly became the norm as the 19th century progressed, both for decorative reasons and because the paint was effective in preventing the walls rotting from damp. Linseed oil was also increasingly used as an inexpensive binder.
In 1866, Sherwin-Williams in the United States opened as a large paint-maker and invented a paint that could be used from the tin without preparation.
It was only when the stimulus of World War II created a shortage of linseed oil in the supply market that artificial resins, or alkyds, were invented. Cheap and easy to make, they held the color well and lasted for a long time.[15]
In the 21st century, "paints" that used structural color were created. Aluminium flakes dotted with smaller aluminium nanoparticles could be tuned to produce arbitrary colors by adjusting the nanoparticle sizes rather than picking/mixing minerals to do so. These paints weighed a tiny fraction of the weight of conventional paints, a particular advantage in air and road vehicles. They reflect heat from sunlight and do not break down outdoors. Preliminary experiments suggest it can reduce temperatures by 20 to 30 degrees Fahrenheit vs conventional paint. Its constituents are also less toxic.[16]
Making the paint starts with a thin double-sided mirror. The researchers deposited metallic nanoparticles on both sides of the sheet. Large sheets were ground to produce small flakes.[16]
The binder is the film-forming component of paint,[17] and the vehicle is composed of binder; if it is necessary to thin it with a diluent like solvent or water, it is a combination of binder and diluent.[18][19] In this case, once the paint has dried or cured very nearly all of the diluent has evaporated and only the binder is left on the coated surface. Thus, an important quantity in coatings formulation is the "vehicle solids", sometimes called the "resin solids" of the formula. This is the proportion of the wet coating weight that is binder, i.e., the polymer backbone of the film that will remain after drying or curing is complete. The volume of paint after it has dried, therefore only leaving the solids, is expressed as the volume solid.
The binder is the only component that is always present among all the various types of formulations. Many binders must be thick enough to be applied and thinned. The type of thinner, if present, varies with the binder.
The binder imparts properties such as gloss, durability, flexibility, and toughness.[20]
Binders can be categorized according to the mechanisms for film formation. Thermoplastic mechanisms include drying and coalescence. Drying refers to simply evaporating the solvent or thinner to leave a coherent film behind. Coalescence refers to a mechanism that involves drying followed by actual interpenetration and fusion of formerly discrete particles. Thermoplastic film-forming mechanisms are sometimes described as "thermoplastic cure," but that is a misnomer because no chemical curing reactions are required to knit the film. On the other hand, thermosetting mechanisms are true curing mechanisms involving chemical reaction(s) among the polymers that make up the binder.[21]
Some films are formed by simply cooling the binder. For example, encaustic or wax paints are liquid when warm, and harden upon cooling. In many cases, they re-soften or liquify if reheated.
Paints that dry by solvent evaporation and contain the solid binder dissolved in a solvent are known as lacquers. A solid film forms when the solvent evaporates. Because no chemical crosslinking is involved, the film can re-dissolve in solvent; lacquers are unsuitable for applications where chemical resistance is important. Classic nitrocellulose lacquers fall into this category, as do non-grain raising stains composed of dyesin solvent. Performance varies by formulation, but lacquers generally tend to have better UV resistance and lower corrosion resistance than comparable systems that cure by polymerization or coalescence.
The paint type known as Emulsion in the UK and Latex in the United States is a water-borne dispersion of sub-micrometer polymer particles. These terms in their respective countries cover all paints that use synthetic polymers such as acrylic, vinyl acrylic (PVA), styrene acrylic, etc. as binders.[22] The term "latex" in the context of paint in the United States simply means an aqueous dispersion; latex rubber from the rubber tree is not an ingredient. These dispersions are prepared by emulsion polymerization. Such paints cure by a process called coalescence where first the water and then the trace, or coalescing, solvent, evaporate and draw together and soften the binder particles and fuse them together into irreversibly bound networked structures, so that the paint cannot redissolve in the solvent/water that originally carried it. The residual surfactants in paint, as well as hydrolytic effects with some polymers cause the paint to remain susceptible to softening and, over time, degradation by water. The general term of latex paint is usually used in the United States, while the term emulsion paint is used for the same products in the UK, and the term latex paint is not used at all.
Paints that cure by polymerization are generally one- or two-package coatings that polymerize by way of a chemical reaction and cure into a cross-linked film. Depending on composition, they may need to dry first by evaporation of solvent. Classic two-package epoxies or polyurethanes[23] would fall into this category.[24]
The "drying oils", counter-intuitively, cure by a crosslinking reaction even if they are not put through an oven cycle and seem to dry in air. The film formation mechanism of the simplest examples involves the first evaporation of solvents followed by a reaction with oxygen from the environment over a period of days, weeks, and even months to create a crosslinked network.[18] Classic alkyd enamels would fall into this category. Oxidative cure coatings are catalyzed by metal complex driers such as cobalt naphthenate though cobalt octoate is more common.
Recent environmental requirements restrict the use of volatile organic compounds (VOCs), and alternative means of curing have been developed, generally for industrial purposes. UV curing paints, for example, enable formulation with very low amounts of solvent, or even none at all. This can be achieved because of the monomers and oligomers used in the coating have relatively very low molecular weight, and are therefore low enough in viscosity to enable good fluid flow without the need for additional thinner. If solvent is present in significant amounts, generally it is mostly evaporated first and then crosslinking is initiated by ultraviolet light. Similarly, powder coatings contain no solvent. Flow and cure are produced by the heating of the substrate after electrostatic application of the dry powder.[25]
So-called "catalyzed" lacquers" or "crosslinking latex" coatings are designed to form films by a combination of methods: classic drying plus a curing reaction that benefits from the catalyst. There are paints called plastisols/organosols, which are made by blending PVC granules with a plasticiser. These are stoved and the mix coalesces.
The main purposes of the diluent are to dissolve the polymer and adjust the viscosity of the paint. It is volatile and does not become part of the paint film. It also controls flow and application properties, and in some cases can affect the stability of the paint while in liquid state. Its main function is as the carrier for the non-volatile components. To spread heavier oils (for example, linseed) as in oil-based interior house paint, a thinner oil is required. These volatile substances impart their properties temporarily—once the solvent has evaporated, the remaining paint is fixed to the surface.
This component is optional: some paints have no diluent.
Water is the main diluent for water-borne paints, even the co-solvent types.
Pigments are solid particles or flakes incorporated in the paint, usually to contribute color to the paint film. Pigments impart color by selective absorption of certain wavelengths of light and/or by scattering or reflecting light. The particle size of the pigment is critical to the light-scattering mechanism. The size of such particles can be measured with a Hegman gauge. Dyes, on the other hand, are dissolve in the paint and impart color only by the selective absorption mechanism.[26] Paints can be formulated with only pigments, only dyes, both, or neither.
Pigments can also be used to give the paint special physical or optical properties, as opposed to imparting color, in which case they are called functional pigments.[27] Fillers or extenders are an important class of the functional pigments. These are typically used to build film thickness and/or reduce the cost of the paint, or they can impart toughness and texture to the film.[28] Fillers are usually cheap and inert materials, such as diatomaceous earth, talc, lime, barytes, clay, etc. Floor paints that must resist abrasion may contain fine quartz sand as a filler.
Sometimes, a single pigment can serve both decorative and functional purposes. For example some decorative pigments protect the substrate from the harmful effects of ultraviolet light by making the paint opaque to these wavelengths, i.e. by selectively absorbing them. These hiding pigments include titanium dioxide, phthalo blue, red iron oxide, and many others.
Some pigments are toxic, such as the lead pigments that are used in lead paint. Paint manufacturers began replacing white lead pigments with titanium white (titanium dioxide), before lead was banned in paint for residential use in 1978 by the US Consumer Product Safety Commission. The titanium dioxide used in most paints today is often coated with silica/alumina/zirconium for various reasons, such as better exterior durability, or better hiding performance (opacity) promoted by more optimal spacing within the paint film.[29]
Micaceous iron oxide (MIO) is another alternative to lead for protection of steel, giving more protection against water and light damage than most paints. When MIO pigments are ground into fine particles, most cleave into shiny layers, which reflect light, thus minimising UV degradation and protecting the resin binder. Most pigments used in paint tend to be spherical, but lamellar pigments, such as glass flake and MIO have overlapping plates, which impede the path of water molecules.[30] For optimum performance MIO should have a high content of thin flake-like particles resembling mica. ISO 10601 sets two levels of MIO content.[31] MIO is often derived from a form of hematite.
Pigments can be classified as either natural or synthetic. Natural pigments are taken from the earth or plant sources and include colorants such as metal oxides or carbon black, or various clays, calcium carbonate, mica, silicas, and talcs. Synthetics include a host of colorants created in the lab as well as engineered molecules, calcined clays, blanc fixe, precipitated calcium carbonate, and synthetic pyrogenic silicas. The pigments and dyes that are used as colorants are classified by chemical type using the Color Index system, which is commercially significant.[32]
Besides the three main categories of ingredients (binder, diluent, pigment), paint can have a wide variety of miscellaneous additives, which are usually added in small amounts, yet provide a significant effect on the product. Some examples include additives to modify texture, surface tension, improve flow properties, improve the finished appearance, increase wet edge, improve pigment stability, impart antifreeze properties, control foaming, control skinning, create acrylic pouring cells, etc. Other types of additives include catalysts, thickeners, stabilizers, emulsifiers, texturizers, adhesion promoters, UV stabilizers, flatteners (de-glossing agents), biocides to fight bacterial growth and the like.
Additives normally do not significantly alter the percentages of individual components in a formulation.[33]
Various technologies exist for making paints that change color. Thermochromic ink and coatings contain materials that change conformation when heat is applied or removed, and so they change color. Liquid crystals have been used in such paints, such as in the thermometer strips and tapes used in aquaria and novelty/promotional thermal cups and straws.
Photochromic materials are used to make eyeglasses and other products. Similar to thermochromic molecules, photochromic molecules change conformation when light energy is applied or removed, and so they change color.
Color-changing paints can also be made by adding halochromic compounds or other organic pigments. One patent[34] cites use of these indicators for wall coating applications for light-colored paints. When the paint is wet it is pink in color but upon drying it regains its original white color. As cited in patent, this property of the paint enabled two or more coats to be applied on a wall properly and evenly. The previous coats having dried would be white whereas the new wet coat would be distinctly pink. Ashland Inc. introduced foundry refractory coatings with similar principle in 2005[35][36] for use in foundries.
Electrochromic paints change color in response to an applied electric current. Car manufacturer Nissan has been reportedly working on an electrochromic paint, based on particles of paramagneticiron oxide. When subjected to an electromagnetic field the paramagnetic particles change spacing, modifying their color and reflective properties. The electromagnetic field would be formed using the conductive metal of the car body.[37] Electrochromic paints can be applied to plastic substrates as well, using a different coating chemistry. The technology involves using special dyes that change conformation when an electric current is applied across the film itself. This new technology has been used to achieve glare protection at the touch of a button in passenger airplane windows.
Color can also change depending on viewing angle, using iridescence, for example, in ChromaFlair.
Since the time of the Renaissance, siccative(drying) oil paints, primarily linseed oil, have been the most commonly used kind of paints in fine art applications; oil paint is still common today. However, in the 20th century, new water-borne paints such acrylic paints, entered the market with the development of acrylic and other latex paints. Milk paints (also called casein), where the medium is derived from the natural emulsion that is milk, were common in the 19th century and are still used. Used by the earliest western artists, Egg tempera (where the medium is an emulsion of raw egg yolk mixed with oil) remains in use as well, as are encaustic wax-based paints. Gouache is an opaque variant of watercolor, which is based around varying levels of translucency; both paints use gum arabic as the binder and water as a thinner. Gouache is also known as 'designer color' or 'body color'.
Poster paint is a distemper paint that has been used primarily in the creation of student works, or by children. There are varying brands of poster paint and depending on the brand, the quality will differ. More inexpensive brands will often crack or fade over time if they are left on a poster for an extended time.

Paint can be applied as a solid, a gas, a gaseous suspension (aerosol) or a liquid. Techniques vary depending on the practical or artistic results desired.
As a solid (usually used in industrial and automotive applications), the paint is applied as a very fine powder, then baked at high temperature. This melts the powder and causes it to adhere to the surface. The reasons for doing this involve the chemistries of the paint, the surface itself, and perhaps even the chemistry of the substrate (the object being painted). This is called "powder coating" an object.
In a gas phase application, the coating composition is introduced (if gaseous), vaporized (if liquid) or sublimed (if solid) then deposited on a distant substrate, often under vacuum. These applications are classed broadly into physical vapor deposition methods like sputtering or vacuum deposition, in which solid or liquid starting materials produce a vapor that condenses on the substrate; or chemical vapor deposition methods, in which gaseous starting materials chemically react with the substrate to form a coating. These techniques are especially important in the electronics and optical industries.[38]
As a gaseous suspension, liquid paint is aerosolized by the force of compressed air or by the action of high-pressure compression of the paint itself, and the paint is turned into small droplets that travel to the article to be painted. Alternate methods are airless spray, hot spray, hot airless spray, and any of these with an electrostatic spray included. There are numerous electrostatic methods available. The reasons for doing this include:
The application mechanism is air and thus no solid object touches the object being painted;
The distribution of the paint is uniform, so there are no sharp lines;
It is possible to deliver very small amounts of paint;
Painting multiple items at once quickly and efficiently;
A chemical (typically a solvent) can be sprayed along with the paint to dissolve together both the delivered paint and the chemicals on the surface of the object being painted;
Some chemical reactions in paint involve the orientation of the paint molecules.
In a liquid application, paint can be applied by direct application using brushes, paint rollers, blades, scrapers, other instruments, or body parts such as fingers and thumbs.
Rollers generally have a handle that allows for different lengths of poles to be attached, allowing painting at different heights. Generally, roller application requires two coats for an even color. A roller with a thicker nap is used to apply paint on uneven surfaces. Edges are often finished with an angled brush.
For a flat (matte) finish, a 1/2" nap roller would most likely be used
For an eggshell finish, a 3/8" nap roller would most likely be used
For a satin or pearl finish, a 3/8" nap roller would most likely be used
For a semi-gloss or gloss finish, a 3/16" nap roller would most likely be used[39]
After liquid paint is applied, there is an interval during which it can be blended with additional painted regions (at the "wet edge") called "open time". The open time of an oil or alkyd-based emulsion paint can be extended by adding white spirit, similar glycols such as Dowanol (propylene glycol ether) or open time prolongers. This can also facilitate the mixing of different wet paint layers for aesthetic effect. Latex and acrylic emulsions require the use of drying retardants suitable for water-based coatings. Depending on the quality and type of liquid paint used, the open time will vary. Oil paints for instance are renowned for their open time as oil paints allow for artists to blend the colors for extended periods of time without having to add any extending agents.
Dipping used to be the norm for objects such as filing cabinets, but this has been replaced by high-speed air turbine-driven bells with electrostatic spray. Car bodies are primed using cathodic elephoretic primer, which is applied by charging the body depositing a layer of primer. The unchanged residue is rinsed off and the primer stoved.
Many paints tend to separate when stored, the heavier components settling to the bottom, and require mixing before use. Some paint outlets have machines for mixing the paint by shaking the can vigorously for a few minutes.
The opacity and the film thickness of paint may be measured using a drawdown card.
Water-based paints tend to be the easiest to clean up after use; the brushes and rollers can be cleaned with soap and water.
Proper disposal of left over paint is a challenge. Sometimes it can be recycled: Old paint may be usable for a primer coat or an intermediate coat, and paints of similar chemistry can be mixed to make a larger amount of a uniform color.
To dispose of paint it can be dried and disposed of in the domestic waste stream, provided that it contains no prohibited substances (see container). Disposal of liquid paint usually requires special handling and should be treated as hazardous waste, and disposed of according to local regulations.[40][41]

Primer is a preparatory coating put on materials before applying the paint itself. The primed surface ensures better adhesion of the paint, thereby increasing the durability of the paint and providing improved protection for the painted surface. Suitable primers also may block and seal stains, or hide a color that is to be painted over.
Emulsion paints are water-based paints in which the paint material is dispersed in a liquid that consists mainly of water. For suitable purposes this has advantages in fast-drying, low toxicity, low cost, easier application, and easier cleaning of equipment, among other factors.
Varnish and shellac are in effect paints without pigment; they provide a protective coating without substantially changing the color of the surface, though they can emphasise the colour of the material.
Wood stain is a type of paint that is formulated to be very "thin", meaning low in viscosity, so that the pigment soaks into a material such as wood rather than remaining in a film on the surface. Stain is mainly dispersed pigment or dissolved dye plus binder material in a solvent. It is designed to add color without providing a surface coating.
Lacquer is a solvent-based paint or varnish that produces an especially hard, durable finish. Usually it is a rapidly drying formulation.
Enamel paint is formulated to give an especially hard, usually glossy, finish. Some enamel paints contain fine glass powder or metal flake instead of the color pigments in standard oil-based paints. Enamel paint sometimes is mixed with varnish or urethane to improve its shine and hardness.
A glaze is an additive used with paint to slow drying time and increase translucency, as in faux painting and for some artistic effects.
A roof coating is a fluid that sets as an elastic membrane that can stretch without harm. It provides UV protection to polyurethane foam and is widely used in roof restoration.
Fingerpaints are formulations suitable for application with the fingers; they are popular for use by children in primary school activities.
Inks are similar to paints, except that they are typically made using finely ground pigments or dyes, and are not designed to leave a thick film of binder. They are used largely for writing, printing, or calligraphy.
Anti-graffiti coatings are used to defeat the marking of surfaces by graffiti artists or vandals. There are two categories of anti-graffiti coatings: sacrificial and non-bonding:
Sacrificial coatings are clear coatings that allow the removal of graffiti, usually by washing the surface with high-pressure water that removes the graffiti together with the coating (hence the term "sacrificial"). After removal of the graffiti, the sacrificial coating must be re-applied for continued protection. Such sacrificial protective coatings are most commonly used on natural-looking masonry surfaces, such as statuary and marble walls, and on rougher surfaces that are difficult to clean.
Non-bonding coatings are clear, high-performance coatings, usually catalyzed polyurethanes, that do not bond strongly to paints used for graffiti. Graffiti on such a surface can be removed with a solvent wash, without damaging either the underlying surface or the protective non-bonding coating. These coatings work best on smooth surfaces, and are especially useful on decorative surfaces such as mosaics or painted murals, which might be expected to suffer harm from high pressure sprays.
Urine-repellent paint is a very hydrophobic (water-repellent) paint. It has been used by cities and other property owners to deter men from urinating against walls, as the urine splashes back on their shoes, instead of dripping down the wall.[42][43][44]
Anti-climb paint is a non-drying paint that appears normal but is extremely slippery. It is useful on drainpipes and ledges to deter burglars and vandals from climbing them, and is found in many public places. When a person attempts to climb objects coated with the paint, it rubs off onto the climber, as well as making it hard for them to climb.
Anti-fouling paint, or bottom paint, prevents barnacles and other marine organisms from adhering to the hulls of ships.
Insulative paint or insulating paint, reduces the rate of thermal transfer through a surface it's applied to. One type of formulation is based on the addition of hollow microspheres to any suitable type of paint.
Anti-slip paint contains chemicals or grit to increase the friction of a surface so as to decrease the risk of slipping, particularly in wet conditions.
Road marking paint[45] is specially used to marking and painting road traffic signs and lines, to form a durable coating film on the road surface. It must be fast-drying, provide a thick coating, and resist wear and slipping, especially in wet conditions.
Luminous paint or luminescent paint is paint that exhibits luminescence. In other words, it gives off visible light through fluorescence, phosphorescence, or radioluminescence.
Flat Finish paint is generally used on ceilings or walls that are in bad shape. This finish is useful for hiding imperfections in walls and it is economical in effectively covering large areas. However, this finish is not easily washable and is subject to staining.
Matte Finish is generally similar to flat finish, but such paints commonly offer superior washability and coverage. (See Gloss and matte paint.)
Eggshell Finish has some sheen, supposedly like that of the shell on an egg. This finish provides great washability but is not very effective at hiding imperfections on walls and similar surfaces. The eggshell finish is valued for bathrooms because it is washable and water-repellent, so it tends not to peel in a wet environment.
Pearl (Satin) Finish is very durable in terms of washability and resistance to moisture, even in comparison to an eggshell finish. It protects walls from dirt, moisture, and stains. Accordingly, it is exceptionally valuable for bathrooms, furniture, and kitchens, but it is shinier than eggshell, so it is even more prone to show imperfections. It has a soft, velvety appearance that is perfect for creating a luxurious feel in any room. Satin paint is also very durable and easy to clean, making it ideal for high-traffic areas like kitchens and bathrooms.[46]
Semi-Gloss Finish typically is used on trim to emphasize detail and elegance, and to show off woodwork, such as on doors and furniture. It provides a shiny surface and provides good protection from moisture and stains on walls. Its gloss does however emphasize imperfections on the walls and similar surfaces. It is popular in schools and factories where washability and durability are the main considerations.[47]
High-gloss paint is a highly glossy form of paint that is light reflecting and has a mirror-like look. It pairs well with other finishes. While it is highly durable and easy to clean, high gloss paint is known for obvious visibility of imperfections like scratches and dents.[48]
The main reasons for paint failure after application on the surface are the applicator and improper treatment of the surface.
Defects or degradation can be attributed to:
Dilution
This usually occurs when the dilution of the paint is not done as per manufacturers recommendation. There can be a case of over dilution and under dilution, as well as dilution with the incorrect diluent.
Contamination
Foreign contaminants can cause various film defects.
Peeling/Blistering
Most commonly due to improper surface treatment before application and inherent moisture/dampness being present in the substrate. The degree of blistering can be assessed according to ISO 4628 Part 2 or ASTM Method D714 (Standard Test Method for Evaluating Degree of Blistering of Paints).
Chalking
Chalking is the progressive powdering of the paint film on the painted surface. The primary reason for the problem is polymer degradation of the paint matrix due to exposure of UV radiation in sunshine and condensation from dew. The degree of chalking varies as epoxies react quickly while acrylics and polyurethanes can remain unchanged for long periods.[49] The degree of chalking can be assessed according to International Standard ISO 4628 Part 6 or 7 or American Society of Testing and Materials(ASTM) Method D4214 (Standard Test Methods for Evaluating the Degree of Chalking of Exterior Paint Films).
Cracking
Cracking of paint film is due to the unequal expansion or contraction of paint coats. It usually happens when the coats of the paint are not allowed to cure/dry completely before the next coat is applied. The degree of cracking can be assessed according to International Standard ISO 4628 Part 4 or ASTM Method D661 (Standard Test Method for Evaluating Degree of Cracking of Exterior Paints). Cracking can also occur when the paint is applied to a surface that is incompatible or unstable. For instance, clay that hasn't dried completely when painted will cause the paint to crack due to the residual moisture in the clay.
Erosion
Erosion is very quick chalking. It occurs due to external agents like air, water etc. It can be evaluated using ASTM Method ASTM D662 (Standard Test Method for Evaluating Degree of Erosion of Exterior Paints). The generation of acid by fungal species can be a significant component of erosion of painted surfaces.[50] The fungus Aureobasidium pullulans is known for damaging wall paints.[51]
Volatile organic compounds (VOCs) in paint are considered harmful to the environment and especially for people who work with them on a regular basis. Extensive exposure to these vapours has been strongly related to organic solvent syndrome, although a definitive relation has yet to be fully established.[52] The controversial solvent 2-butoxyethanol is also used in paint production.[53] Jurisdictions such as Canada, China, the EU, India, the United States, and South Korea have definitions for VOCs in place, along with regulations to limit the use of VOCs in consumer products such as paint.[54][55]
In the US, environmental regulations, consumer demand, and advances in technology led to the development of low-VOC and zero-VOC paints and finishes. These new paints are widely available and meet or exceed the old high-VOC products in performance and cost-effectiveness while having significantly less impact on human and environmental health.[56]
Globally, the most widely accepted standard for acceptable levels of VOC in paint is Green Seal’s GS-11 Standards from the US which defines different VOC levels acceptable for different types of paint based on use case and performance requirements.
A polychlorinated biphenyl (PCB) was reported (published in 2009) in air samples collected in Chicago, Philadelphia, the Arctic, and several sites around the Great Lakes. PCB is a global pollutant and was measured in the wastewater effluent from paint production. The widespread distribution of PCB suggests volatilization of this compound from surfaces, roofs etc. PCB is present in consumer goods including newspapers, magazines, and cardboard boxes, which usually contain color pigments. Therefore, a hypothesis exists that PCB congeners are present as byproduct in some current commercial pigments.[57]
Research is ongoing to remove heavy metals from paint formulations completely.[58]
The ongoing scrutiny of the environmental impact of plastics in paint production is reminiscent of previous investigations into the use of lead in paints. This assessment is driven by accumulating evidence that underscores the role of paint as a significant contributor to microplastic pollution. In 2019, of the 44.4 million tons of globally produced paint, 95 percent was plastic-based. Further, a 2022 study by Environmental Action revealed that approximately 58 percent of the microplastics found in oceans and waterways could be traced back to paint.
Efforts to mitigate this environmental issue have spurred the development and exploration of alternatives to plastic-based paints, such as those derived from linseed, walnut, milk, and limewash. However, their cost is a significant deterrent to the widespread adoption of these environmentally-friendly alternatives. As of 2023, a gallon of plastic-based paint may cost around $20 to $30, however the price for specialized paint, such as graphene and lime, ranges from $34 to $114 per gallon, underlining the financial challenges associated with transitioning from plastic-based paints.[59]

While a variety of theories have been postulated for the etymological origins of Canada, the name is now accepted as coming from the St. Lawrence Iroquoian word kanata, meaning 'village' or 'settlement'.[9] In 1535, Indigenous inhabitants of the present-day Quebec City region used the word to direct French explorer Jacques Cartier to the village of Stadacona.[10] Cartier later used the word Canada to refer not only to that particular village but to the entire area subject to Donnacona (the chief at Stadacona);[10] by 1545, European books and maps had begun referring to this small region along the Saint Lawrence River as Canada.[10]
Upon Confederation in 1867, Canada was adopted as the legal name for the new country at the London Conference and the word dominion was conferred as the country's title.[14] By the 1950s, the term Dominion of Canada was no longer used by the United Kingdom, which considered Canada a "realm of the Commonwealth".[15]
The Canada Act 1982, which brought the Constitution of Canada fully under Canadian control, referred only to Canada. Later that year, the name of the national holiday was changed from Dominion Day to Canada Day.[16]
The Indigenous population at the time of the first European settlements is estimated to have been between 200,000[23] and two million,[24] with a figure of 500,000 accepted by Canada's Royal Commission on Aboriginal Peoples.[25] As a consequence of European colonization, the Indigenous population declined by forty to eighty percent.[26] The decline is attributed to several causes, including the transfer of European diseases, to which they had no natural immunity,[27] conflicts over the fur trade, conflicts with the colonial authorities and settlers, and the loss of Indigenous lands to settlers and the subsequent collapse of several nations' self-sufficiency.[28]
It is believed that the first documented European to explore the east coast of Canada was Norse explorer Leif Erikson.[38] In approximately 1000 AD, the Norse built a small short-lived encampment that was occupied sporadically for perhaps 20 years at L'Anse aux Meadows on the northern tip of Newfoundland.[39] No further European exploration occurred until 1497, when seafarer John Cabot explored and claimed Canada's Atlantic coast in the name of Henry VII of England.[40] In 1534, French explorer Jacques Cartier explored the Gulf of Saint Lawrence where, on July 24, he planted a 10-metre (33 ft) cross bearing the words, "long live the King of France", and took possession of the territory New France in the name of King Francis I.[41] The early 16th century saw European mariners with navigational techniques pioneered by the Basque and Portuguese establish seasonal whaling and fishing outposts along the Atlantic coast.[42] In general, early settlements during the Age of Discovery appear to have been short-lived due to a combination of the harsh climate, problems with navigating trade routes and competing outputs in Scandinavia.[43]
The English established additional settlements in Newfoundland in 1610 along with settlements in the Thirteen Colonies to the south.[49] A series of four wars erupted in colonial North America between 1689 and 1763; the later wars of the period constituted the North American theatre of the Seven Years' War.[50] Mainland Nova Scotia came under British rule with the 1713 Treaty of Utrecht and Canada and most of New France came under British rule in 1763 after the Seven Years' War.[51]
The Royal Proclamation of 1763 established First Nation treaty rights, created the Province of Quebec out of New France, and annexed Cape Breton Island to Nova Scotia.[16] St John's Island (now Prince Edward Island) became a separate colony in 1769.[53] To avert conflict in Quebec, the British Parliament passed the Quebec Act 1774, expanding Quebec's territory to the Great Lakes and Ohio Valley.[54] More importantly, the Quebec Act afforded Quebec special autonomy and rights of self-administration at a time when the Thirteen Colonies were increasingly agitating against British rule.[55] It re-established the French language, Catholic faith, and French civil law there, staving off the growth of an independence movement in contrast to the Thirteen Colonies.[56] The Proclamation and the Quebec Act in turn angered many residents of the Thirteen Colonies, further fuelling anti-British sentiment in the years prior to the American Revolution.[16]
After the successful American War of Independence, the 1783 Treaty of Paris recognized the independence of the newly formed United States and set the terms of peace, ceding British North American territories south of the Great Lakes and east of the Mississippi River to the new country.[57] The American war of independence also caused a large out-migration of Loyalists, the settlers who had fought against American independence. Many moved to Canada, particularly Atlantic Canada, where their arrival changed the demographic distribution of the existing territories. New Brunswick was in turn split from Nova Scotia as part of a reorganization of Loyalist settlements in the Maritimes, which led to the incorporation of Saint John, New Brunswick, as Canada's first city.[58] To accommodate the influx of English-speaking Loyalists in Central Canada, the Constitutional Act of 1791 divided the province of Canada into French-speaking Lower Canada (later Quebec) and English-speaking Upper Canada (later Ontario), granting each its own elected legislative assembly.[59]
The Canadas were the main front in the War of 1812 between the United States and the United Kingdom. Peace came in 1815; no boundaries were changed.[61] Immigration resumed at a higher level, with over 960,000 arrivals from Britain between 1815 and 1850.[62] New arrivals included refugees escaping the Great Irish Famine as well as Gaelic-speaking Scots displaced by the Highland Clearances.[63] Infectious diseases killed between 25 and 33 percent of Europeans who immigrated to Canada before 1891.[23]
The desire for responsible government resulted in the abortive Rebellions of 1837.[64] The Durham Report subsequently recommended responsible government and the assimilation of French Canadians into English culture.[16] The Act of Union 1840 merged the Canadas into a united Province of Canada and responsible government was established for all provinces of British North America east of Lake Superior by 1855.[65] The signing of the Oregon Treaty by Britain and the United States in 1846 ended the Oregon boundary dispute, extending the border westward along the 49th parallel. This paved the way for British colonies on Vancouver Island (1849) and in British Columbia (1858).[66] The Anglo-Russian Treaty of Saint Petersburg (1825) established the border along the Pacific coast, but, even after the US Alaska Purchase of 1867, disputes continued about the exact demarcation of the Alaska–Yukon and Alaska–British Columbia border.[67]
Following three constitutional conferences, the British North America Act, 1867 officially proclaimed Canadian Confederation on July 1, 1867, initially with four provinces: Ontario, Quebec, Nova Scotia, and New Brunswick.[69] Canada assumed control of Rupert's Land and the North-Western Territory to form the Northwest Territories, where the Métis' grievances ignited the Red River Rebellion and the creation of the province of Manitoba in July 1870.[70] British Columbia and Vancouver Island (which had been united in 1866) joined the confederation in 1871 on the promise of a transcontinental railway extending to Victoria in the province within 10 years,[71] while Prince Edward Island joined in 1873.[72] In 1898, during the Klondike Gold Rush in the Northwest Territories, Parliament created the Yukon Territory. Alberta and Saskatchewan became provinces in 1905.[72] Between 1871 and 1896, almost one quarter of the Canadian population emigrated south to the US.[73]
The financial crisis of the Great Depression led the Dominion of Newfoundland to relinquish responsible government in 1934 and become a Crown colony ruled by a British governor.[90] After two referendums, Newfoundlanders voted to join Canada in 1949 as a province.[91]
Finally, another series of constitutional conferences resulted in the Canada Act 1982, the patriation of Canada's constitution from the United Kingdom, concurrent with the creation of the Canadian Charter of Rights and Freedoms.[97] Canada had established complete sovereignty as an independent country under its own monarchy.[98] In 1999, Nunavut became Canada's third territory after a series of negotiations with the federal government.[99]
Average winter and summer high temperatures across Canada vary from region to region. Winters can be harsh in many parts of the country, particularly in the interior and Prairie provinces, which experience a continental climate, where daily average temperatures are near −15 °C (5 °F), but can drop below −40 °C (−40 °F) with severe wind chills.[129] In non-coastal regions, snow can cover the ground for almost six months of the year, while in parts of the north snow can persist year-round. Coastal British Columbia has a temperate climate, with a mild and rainy winter. On the east and west coasts, average high temperatures are generally in the low 20s °C (70s °F), while between the coasts, the average summer high temperature ranges from 25 to 30 °C (77 to 86 °F), with temperatures in some interior locations occasionally exceeding 40 °C (104 °F).[130]
Much of Northern Canada is covered by ice and permafrost. The future of the permafrost is uncertain because the Arctic has been warming at three times the global average as a result of climate change in Canada.[131] Canada's annual average temperature over land has risen by 1.7 °C (3.1 °F), with changes ranging from 1.1 to 2.3 °C (2.0 to 4.1 °F) in various regions, since 1948.[119] The rate of warming has been higher across the North and in the Prairies.[132] In the southern regions of Canada, air pollution from both Canada and the United States—caused by metal smelting, burning coal to power utilities, and vehicle emissions—has resulted in acid rain, which has severely impacted waterways, forest growth, and agricultural productivity.[133] Canada is one of the largest greenhouse gas emitters globally,[134] with emissions increased by 16.5 percent between 1990 and 2022.[135]
The monarchy is the source of sovereignty and authority in Canada.[166] However, while the governor general or monarch may exercise their power without ministerial advice in rare crisis situations,[167] the use of the executive powers (or royal prerogative) is otherwise directed by the Cabinet, a committee of ministers of the Crown responsible to the elected House of Commons and chosen and headed by the prime minister,[168] the head of government. To ensure the stability of government, the governor general will usually appoint as prime minister the person who is the current leader of the political party that can obtain the confidence of a majority of members in the House.[169] The Prime Minister's Office (PMO) is one of the most powerful institutions in government, initiating most legislation for parliamentary approval and selecting for appointment by the Crown the governor general, lieutenant governors, senators, federal court judges, and heads of Crown corporations and government agencies.[167] The leader of the party with the second-most seats usually becomes the leader of the Official Opposition and is part of an adversarial parliamentary system intended to keep the government in check.[170]
The Parliament of Canada passes all federal statute laws. It comprises the monarch, the House of Commons, and the Senate. While Canada inherited the British concept of parliamentary supremacy, this was later, with the enactment of the Constitution Act, 1982, all but completely superseded by the American notion of the supremacy of the law.[172]
Each of the 343 members of Parliament in the House of Commons is elected by simple plurality in an electoral district or riding. The Constitution Act, 1982, requires that no more than five years pass between elections, although the Canada Elections Act limits this to four years with a "fixed" election date in October; general elections still must be called by the governor general and can be triggered by either the advice of the prime minister or a lost confidence vote in the House.[173] The 105 members of the Senate, whose seats are apportioned on a regional basis, serve until age 75.[174]
Canadian federalism divides government responsibilities between the federal government and the 10 provinces. Provincial legislatures are unicameral and operate in parliamentary fashion similar to the House of Commons.[175] Canada's three territories also have legislatures, but these are not sovereign, have fewer constitutional responsibilities than the provinces,[176] and differ structurally from their provincial counterparts.[177]
The Constitution of Canada is the supreme law of the country and consists of written text and unwritten conventions.[178] The Constitution Act, 1867 (known as the British North America Act, 1867 prior to 1982), affirmed governance based on parliamentary precedent and divided powers between the federal and provincial governments.[179] The Statute of Westminster, 1931, granted full autonomy, and the Constitution Act, 1982, ended all legislative ties to Britain, as well as adding a constitutional amending formula and the Canadian Charter of Rights and Freedoms.[180] The Charter guarantees basic rights and freedoms that usually cannot be overridden by any government; a notwithstanding clause allows Parliament and the provincial legislatures to override certain sections of the Charter for a period of five years.[181]
Canada's judiciary interprets laws and has the power to strike down acts of Parliament that violate the constitution. The Supreme Court of Canada is the highest court, final arbiter, and has been led since 2017 by Richard Wagner, the Chief Justice of Canada.[182] The governor general appoints the court's nine members on the advice of the prime minister and minister of justice.[183] The federal Cabinet also appoints justices to superior courts in the provincial and territorial jurisdictions.[184]
Common law prevails everywhere except Quebec, where civil law predominates.[185]Criminal law is solely a federal responsibility and is uniform throughout Canada.[186]Law enforcement, including criminal courts, is officially a provincial responsibility, conducted by provincial and municipal police forces.[187] In most rural and some urban areas, policing responsibilities are contracted to the federal Royal Canadian Mounted Police.[188]
The major difference between a Canadian province and a territory is that provinces receive their sovereignty from the Crown[196] and power and authority from the Constitution Act, 1867, whereas territorial governments have powers delegated to them by the Parliament of Canada[197] and the commissioners represent the King in his federal Council,[198] rather than the monarch directly. The powers flowing from the Constitution Act, 1867, are divided between the federal government and the provincial governments to exercise exclusively[199] and any changes to that arrangement require a constitutional amendment, while changes to the roles and powers of the territories may be performed unilaterally by the Parliament of Canada.[200]
Canada's role in developing peacekeeping and its participation in major peacekeeping initiatives during the 20th century has played a major role in its positive global image.[221] Peacekeeping is deeply embedded in Canadian culture and a distinguishing feature that Canadians feel sets their foreign policy apart from the United States.[222] Canada has long been reluctant to participate in military operations that are not sanctioned by the United Nations,[223] such as the Vietnam War or the 2003 invasion of Iraq.[223] Since the 21st century, Canadian direct participation in UN peacekeeping efforts has greatly declined.[224] The large decrease was a result of Canada directing its participation to UN-sanctioned military operations through the North Atlantic Treaty Organization, rather than directly through the UN.[225] The change to participation via NATO has resulted in a shift towards more militarized and deadly missions rather than traditional peacekeeping duties.[226]
The Toronto financial district is the second-largest financial centre in North America, the seventh-largest globally in employment and the heart of Canada's finance industry.[227]
Canada's mixed-market economy[228] is highly developed, ranking as the world's ninth-largest by nominal GDP as of 2023[update], at approximately US$2.221 trillion.[229] The country is one of the world's largest trading nations, with a highly globalized economy.[230] In 2021, Canadian trade in goods and services reached $2.016 trillion.[231]Canada's exports totalled over $637 billion, while its imported goods were worth over $631 billion, of which approximately $391 billion originated from the United States.[231] In 2018, Canada had a trade deficit in goods of $22 billion and a trade deficit in services of $25 billion.[231] The Toronto Stock Exchange is the ninth-largest stock exchange in the world by market capitalization, listing over 1,500 companies with a combined market capitalization of over US$2 trillion.[232]
Since the early 20th century, the growth of Canada's manufacturing, mining, and service sectors has transformed the nation from a largely rural economy to an urbanized, industrial one.[245] The Canadian economy is dominated by the service industry, which employs about three-quarters of the country's workforce.[246] Canada has an unusually important primary sector, of which the forestry and petroleum industries are the most prominent components.[247] Many towns in northern Canada, where agriculture is difficult, are sustained by nearby mines or sources of timber.[248]
The 2021 Canadian census enumerated a total population of 36,991,981, an increase of around 5.2 percent over the 2016 figure.[279] It is estimated that Canada's population surpassed 40,000,000 in 2023.[280] The main drivers of population growth are immigration and, to a lesser extent, natural growth.[281] Canada has one of the highest per-capita immigration rates in the world,[282] driven mainly by economic policy and family reunification.[283] A record 483,390 immigrants were admitted in 2024.[284] Canada leads the world in refugee resettlement; it resettled more than 47,600 in 2022.[285] New immigrants settle mostly in major urban areas, such as Toronto, Montreal, and Vancouver.[286]
Canada's population density, at 4.2 inhabitants per square kilometre (11/sq mi), is among the lowest in the world,[279] with approximately 95 percent of the population residing south of the 55th parallel north.[287] About 80 percent of the population lives within 150 kilometres (93 mi) of the border with the contiguous United States.[288] Canada is highly urbanized, with over 80 percent of the population living in urban centres.[289] The majority of Canadians (over 70 percent ) live below the 49th parallel, with 50 percent of Canadians living south of 45°42′ (45.7 degrees) north.[290] The most densely populated part of the country is the Quebec City–Windsor Corridor in Southern Quebec and Southern Ontario along the Great Lakes and the St. Lawrence River.[291]
The majority of Canadians (81.1 percent) live in family households, 12.1 percent report living alone, and 6.8 percent live with other relatives or unrelated persons.[292] Fifty-one percent of households are couples with or without children, 8.7 percent are single-parent households, 2.9 percent are multigenerational households, and 29.3 percent are single-person households.[292]
The country's ten largest self-reported ethnic or cultural origins in 2021 were Canadian[e] (accounting for 15.6 percent of the population), followed by English (14.7 percent), Irish (12.1 percent), Scottish (12.1 percent), French (11.0 percent), German (8.1 percent), Chinese (4.7 percent), Italian (4.3 percent), Indian (3.7 percent), and Ukrainian (3.5 percent).[299]
Of the 36.3million people enumerated in 2021, approximately 25.4million reported being "White", representing 69.8 percent of the population.[294] The Indigenous population representing 5 percent or 1.8million people, grew by 9.4 percent compared to the non-Indigenous population, which grew by 5.3 percent from 2016 to 2021.[300] One out of every four Canadians or 26.5 percent of the population belonged to a non-White and non-Indigenous visible minority,[301][f] the largest of which in 2021 were South Asian (2.6million people; 7.1 percent), Chinese (1.7million; 4.7 percent), Black (1.5million; 4.3 percent), Filipinos (960,000 2.6 percent), Arabs (690,000; 1.9 percent), Latin Americans (580,000; 1.6 percent), Southeast Asians (390,000; 1.1 percent), West Asians (360,000; 1.0 percent), Koreans (220,000; 0.6 percent) and Japanese (99,000; 0.3 percent).[294]
Between 2011 and 2016, the visible minority population rose by 18.4 percent.[303] In 1961, about 300,000 people, less than two percent of Canada's population, were members of visible minority groups.[304] The 2021 census indicated that 8.3million people, or almost one-quarter (23.0 percent) of the population, reported themselves as being or having been a landed immigrant or permanent resident in Canada—above the 1921 census previous record of 22.3 percent.[305] In 2021, India, China, and the Philippines were the top three countries of origin for immigrants moving to Canada.[306]
Quebec's 1974 Official Language Act established French as the only official language of the province.[309] Although more than 82 percent of French-speaking Canadians live in Quebec, there are substantial Francophone populations in New Brunswick, Alberta, and Manitoba, with Ontario having the largest French-speaking population outside Quebec.[310] New Brunswick, the only officially bilingual province, has an Acadian French minority constituting 33 percent of the population.[311] There are also clusters of Acadians in southwestern Nova Scotia, on Cape Breton Island, and in central and western Prince Edward Island.[312]
Other provinces have no official languages as such, but French is used as a language of instruction, in courts, and for other government services, in addition to English. Manitoba, Ontario, and Quebec allow for both English and French to be spoken in the provincial legislatures and laws are enacted in both languages. In Ontario, French has some legal status, but is not fully co-official.[313] There are 11 Indigenous language groups, composed of more than 65 distinct languages and dialects.[314] Several Indigenous languages have official status in the Northwest Territories.[315]Inuktitut is the majority language in Nunavut and is one of three official languages in the territory.[316]
As of the 2021 census, just over 7.8 million Canadians listed a non-official language as their first language. Some of the most common non-official first languages include Mandarin (679,255 first-language speakers), Punjabi (666,585), Cantonese (553,380), Spanish (538,870), Arabic (508,410), Tagalog (461,150), Italian (319,505), German (272,865), and Tamil (237,890).[292] The country is also home to many sign languages, some of which are Indigenous.[317]American Sign Language (ASL) is used across the country due to the prevalence of ASL in primary and secondary schools.[318]Quebec Sign Language (LSQ) is used primarily in Quebec.[319]
Rates of religious adherence have steadily decreased since the 1970s.[321] With Christianity in decline after having once been central and integral to Canadian culture and daily life,[324] Canada has become a post-Christian, secular state.[325] Although the majority of Canadians consider religion to be unimportant in their daily lives,[326] they still believe in God.[327] The practice of religion is generally considered a private matter.[328]
Healthcare in Canada is delivered through the provincial and territorial systems of publicly funded health care, informally called Medicare.[333] It is guided by the provisions of the Canada Health Act of 1984[334] and is universal.[335] Universal access to publicly funded health services "is often considered by Canadians as a fundamental value that ensures national healthcare insurance for everyone wherever they live in the country".[336] Around 30 percent of Canadians' healthcare is paid for through the private sector.[337] This mostly pays for services not covered or partially covered by Medicare, such as prescription drugs, dentistry and optometry.[337] Approximately 65 to 75 percent of Canadians have some form of supplementary health insurance; many receive it through their employers or access secondary social service programs.[338]
In common with many other developed countries, Canada is experiencing an increase in healthcare expenditures due to a demographic shift toward an older population, with more retirees and fewer people of working age. In 2021, the average age in Canada was 41.9 years.[292] Life expectancy is 81.1 years.[339] A 2016 report by the chief public health officer found that 88 percent of Canadians, one of the highest proportions of the population among G7 countries, indicated that they "had good or very good health".[340] Eighty percent of Canadian adults self-report having at least one major risk factor for chronic disease: smoking, physical inactivity, unhealthy eating or excessive alcohol use.[341] Canada has one of the highest rates of adult obesity among OECD countries, contributing to approximately 2.7 million cases of diabetes.[341] Four chronic diseases—cancer (leading cause of death), cardiovascular diseases, respiratory diseases, and diabetes—account for 65 percent of deaths in Canada.[342] There are approximately 8million people aged 15 and older with one or more disabilities in Canada.[343]
In 2024, the Canadian Institute for Health Information estimated that healthcare spending reached $372billion, or 12.4 percent of Canada's GDP for that year.[344] In 2022, Canada's per-capita spending on health expenditures ranked 12th among health-care systems in the OECD.[345] Canada has performed close to, or above the average on the majority of OECD health indicators since the early 2000s, ranking above the average on OECD indicators for wait-times and access to care, with average scores for quality of care and use of resources.[346] The Commonwealth Fund's 2021 report comparing the healthcare systems of the 11 most developed countries ranked Canada second-to-last.[347] Identified weaknesses were comparatively higher infant mortality rate, the prevalence of chronic conditions, long wait times, poor availability of after-hours care, and a lack of prescription drugs and dental coverage.[347] An increasing problem in Canada's health system is a lack of healthcare professionals,[348] and hospital capacity.[349]
Canada by province and territory, showing the percentage of the population aged 25 to 64 who had a bachelor's degree or higher, and the percentage point change from 2016 to 2021[350]
According to a 2022 report by the OECD, Canada is one of the most educated countries in the world;[358] the country ranks first worldwide in the percentage of adults having tertiary education, with over 56 percent of Canadian adults having attained at least an undergraduate college or university degree.[359] Canada spends an average of 5.3 percent of its GDP on education.[360] The country invests heavily in tertiary education (more than US$20,000 per student).[361] As of 2022[update], 89 percent of adults aged 25 to 64 have earned the equivalent of a high-school degree, compared to an OECD average of 75 percent.[362]
Historically, Canada has been influenced by British, French, and Indigenous cultures and traditions.[364] During the 20th century, Canadians with African, Caribbean, and Asian nationalities have added to the Canadian identity and its culture.[365] Canada's culture draws influences from its broad range of constituent nationalities, and policies that promote a just society are constitutionally protected.[366] Since the 1960s, Canada has emphasized human rights and inclusiveness for all its people.[367] Canadian identity shifted from primarily British-based to multicultural between the 1960s and 1970s.[368]
Themes of nature, pioneers, trappers, and traders played an important part in the early development of Canadian symbolism.[377] Modern symbols emphasize the country's geography, northern climate, lifestyles, and the Canadianization of traditional European and Indigenous symbols.[378] The use of the maple leaf as a symbol dates to the early 18th century in New France.[379] The maple leaf is depicted on Canada's current and previous flags and on the arms of Canada.[380] Canada's official tartan, known as the "maple leaf tartan", reflects the colours of the maple leaf through the seasons—green in the spring, gold in the early autumn, red at the first frost, and brown after falling.[381] The arms of Canada are closely modelled after those of the United Kingdom, with French and distinctive Canadian elements replacing or added to those derived from the British version.[382]
Author Margaret Atwood has suggested that during the 1970s Canadian literature was still looking for a national identity.[387]
Canadian literature is often divided into French- and English-language literatures, which are rooted in the literary traditions of France and Britain, respectively.[388] The earliest Canadian narratives were of travel and exploration.[389] This developed into three major themes of historical Canadian literature: nature, frontier life, and Canada's position within the world, all of which tie into the garrison mentality.[390] The evolution of Canadian literature is intricately linked to the country's historical and social contexts, often mirroring the challenges and changes in Canadian society.[391] As Canadian literature progressed into the 20th and 21st centuries, it began to address a broader array of subjects and themes, such as women's rights, LGBTQ rights, immigrant experiences, environmental issues, the relationship with Indigenous peoples, and Canadian values and identity.[392]
Art in Canada is marked by thousands of years of habitation by Indigenous peoples,[397] and, in later times, artists have combined British, French, Indigenous, and American artistic traditions, at times embracing European styles while working to promote nationalism.[398] The nature of Canadian art reflects these diverse origins, as artists have taken their traditions and adapted these influences to reflect the reality of their lives in Canada.[399] The Group of Seven is often considered the first uniquely Canadian artistic group and style of painting.[400]Inuit art since the 1950s has been the traditional gift given to foreign dignitaries by the Canadian government.[401]
Historically, the Catholic Church was the primary patron of art in early Canada, especially Quebec.[402] The Government of Canada has played a role in the development of art, through the department of Canadian Heritage by giving grants to art galleries,[403] as well as by establishing and funding art schools and colleges across the country, and through the Canada Council for the Arts.[404] The Canada Council Art Bank also helps artists by buying and publicizing their work.[405] Great achievements in art in Canada are recognized through various awards and prizes, such as the Molson Prize, the Audain Prize for the Visual Arts, and the Governor General's Visual and Media Arts Awards.[406]
"God Save the King" has been used in Canada since the late 1700s and is the country's de facto royal anthem.[416]Patriotic music by Canadians dates back over 200 years, with "The Bold Canadian", written in 1812, popular throughout the 19th century.[417] "The Maple Leaf Forever", written in 1866, was popular and served as an unofficial national anthem of English Canada.[418] "O Canada", originally composed in French in 1880, also served as an unofficial national anthem during the 20th century and was adopted as the country's official anthem in 1980.[407]
Canadian mass media, both print and digital, and in both official languages, is largely dominated by a "handful of corporations".[422] The largest of these corporations is the country's national public broadcaster, the Canadian Broadcasting Corporation, which also plays a significant role in producing domestic cultural content, operating its own radio and TV networks in both English and French.[423] In addition to the CBC, some provincial governments offer their own public educational TV broadcast services as well, such as TVOntario and Télé-Québec.[424]
Non-news media content in Canada, including film and television, is influenced both by local creators as well as by imports from the United States, the United Kingdom, Australia, and France.[425] In an effort to reduce the amount of foreign-made media, government interventions in television broadcasting can include both regulation of content and public financing.[426]Canadian tax laws limit foreign competition in magazine advertising.[427]
In terms of participation, swimming was the most commonly reported sport by over one-third (35 percent) of Canadians in 2023.[435] This was closely followed by cycling (33 percent) and running (27 percent).[435] The popularity of specific sports varies;[436] in general, the Canadian-born population was more likely to have participated in winter sports such as ice hockey (the most popular young adult team sport),[435]skating, skiing and snowboarding, compared with immigrants, who were more likely to have played soccer (the most popular youth team sport),[437]tennis or basketball.[435] Sports such as golf, volleyball, badminton, bowling, and martial arts are also widely enjoyed at the youth and amateur levels.[438]

^ "The Royal Canadian Navy is composed of approximately 8,400 full-time sailors and 5,100 part-time sailors. The Army is composed of approximately 22,800 full-time soldiers, 18,700 reservists, and 5,000 Canadian Rangers. The Royal Canadian Air Force is composed of approximately 13,000 Regular Force personnel and 2,400 Air Reserve personnel."[219]
^All citizens of Canada are classified as "Canadians" as defined by Canada's nationality laws. "Canadian" as an ethnic group has since 1996 been added to census questionnaires for possible ancestral origin or descent. "Canadian" was included as an example on the English questionnaire and "Canadien" as an example on the French questionnaire.[297] "The majority of respondents to this selection are from the eastern part of the country that was first settled. Respondents generally are visibly European (Anglophones and Francophones) and no longer self-identify with their ethnic ancestral origins. This response is attributed to a multitude or generational distance from ancestral lineage."[298]
^Indigenous peoples are not considered a visible minority in Statistics Canada calculations. Visible minorities are defined by Statistics Canada as "persons, other than Aboriginal peoples, who are non-Caucasian in race or non-white in colour".[302]

The theoretical foundation for these rights was the importance of free political speech and discussion in a democracy.
