The culture of Canada embodies the artistic, culinary, literary, humour, musical, political and social elements that are representative of Canadians. Throughout Canada's history, its culture has been influenced firstly by its indigenous cultures, and later by European culture and traditions, mostly by the British and French. Over time, elements of the cultures of Canada's immigrant populations have become incorporated to form a Canadian cultural mosaic. Certain segments of Canada's population have, to varying extents, also been influenced by American culture due to shared language (in English-speaking Canada), significant media penetration, and geographic proximity.

Canada is often characterized as being "very progressive, diverse, and multicultural". Canada's federal government has often been described as the instigator of multicultural ideology because of its public emphasis on the social importance of immigration. Canada's culture draws from its broad range of constituent nationalities, and policies that promote a just society are constitutionally protected. Canadian policies—such as abortion, euthanasia, same-sex marriage, and cannabis; an emphasis on cultural diversity; significant immigration; abolishing capital punishment; publicly funded health care; higher and more progressive taxation; efforts to eliminate poverty; and strict gun control are social indicators of the country's political and cultural values. Canadians view the country's institutions of health care, military peacekeeping, the national park system, and the Canadian Charter of Rights and Freedoms as integral to their national identity.

The Canadian government has influenced culture with programs, laws and institutions. It has created crown corporations to promote Canadian culture through media, such as the Canadian Broadcasting Corporation (CBC) and the National Film Board of Canada (NFB), and promotes many events which it considers to promote Canadian traditions. It has also tried to protect Canadian culture by setting legal minimums on Canadian content in many media using bodies like the Canadian Radio-television and Telecommunications Commission (CRTC).

For thousands of years, Canada has been inhabited by indigenous peoples from a variety of different cultures and of several major linguistic groupings. Although not without conflict and bloodshed, early European interactions with First Nations and Inuit populations in what is now Canada were arguably peaceful. First Nations and Métis peoples played a critical part in the development of European colonies in Canada, particularly for their role in assisting European coureur des bois and voyageurs in the exploration of the continent during the North American fur trade. Over the course of three centuries, countless North American Indigenous words, inventions, concepts, and games have become an everyday part of Canadian language and use. Many places in Canada, both natural features and human habitations, use indigenous names. The name "Canada" itself derives from the St. Lawrence Huron-Iroquoian word "Kanata" meaning "village" or "settlement". The name of Canada's capital city Ottawa comes from the Algonquin language term "adawe" meaning "to trade".

In the 17th-century, French colonials settled New France in Acadia, in the present-day Maritimes, and in Canada, along the St. Lawrence River in present-day Quebec and Ontario. These regions were under French control from 1534 to 1763. However, the British conquered Acadia in 1710 and conquered Canada in 1760. The British were able to deport most of the Acadians, but they were unable to deport the Canadiens of Canada because they severely outnumbered the British forces. The British therefore had to make deals with Canadiens and hope they would one day become assimilated. The American Revolution, from 1775 to 1783, provoked the migration of 40,000 to 50,000 United Empire Loyalists from the Thirteen Colonies to the newly conquered British lands, which brought American influences to Canada for the first time. Following the War of 1812, many Scottish and English people settled in Upper Canada and Lower Canada. Many Irish people fleeing the Great Famine also arrived between 1845 and 1852.

The Canadian Forces and overall civilian participation in the First World War and Second World War helped to foster Canadian nationalism; however, in 1917 and 1944, conscription crises highlighted the considerable rift along ethnic lines between Anglophones and Francophones. As a result of the First and Second World Wars, the Government of Canada became more assertive and less deferential to British authority. Canada, until the 1940s, was often described as "binational", with the 2 components being the cultural, linguistic and political identities of English Canadians and of French Canadians.

Legislative restrictions on immigration (such as the Continuous journey regulation and Chinese Immigration Act) that had favoured British, American and other European immigrants (such as Dutch, German, Italian, Polish, Swedish and Ukrainian) were amended during the 1960s, resulting in an influx of people of many different ethnicities. By the end of the 20th century, immigrants were increasingly Chinese, Indian, Vietnamese, Jamaican, Filipino, Lebanese, Pakistani and Haitian. By the 21st century Canada had thirty four ethnic groups with at least one hundred thousand members each, of which eleven have over 1,000,000 people and numerous others are represented in smaller numbers. As of 2006^[update], 16.2% of the population self-identify as a visible minority.

Themes and symbols of pioneers, trappers, and traders played an important part in the early development of Canadian culture. Modern Canadian culture as it is understood today can be traced to its time period of westward expansion and nation building. Contributing factors include Canada's unique geography, climate, and cultural makeup. Being a cold country with long winter nights for most of the year, certain unique leisure activities developed in Canada during this period including ice hockey and embracement of the summer indigenous game of lacrosse.
