Multiculturalism in Canada was officially adopted by the government during the 1970s and 1980s. The Canadian federal government has been described as the instigator of multiculturalism as an ideology because of its public emphasis on the social importance of immigration. The 1960s Royal Commission on Bilingualism and Biculturalism is often referred to as the origin of modern political awareness of multiculturalism, resulting in Canada being one of the most multicultural nations in the world. The official state policy of multiculturalism is often cited as one of Canada's significant accomplishments, and a key distinguishing element of Canadian identity and Canadian values.
Multiculturalism is reflected with the law through the Canadian Multiculturalism Act of 1988 and section 27 of the Canadian Charter of Rights and Freedoms and is administered by the Department of Canadian Heritage. The Broadcasting Act of 1991 asserts the Canadian broadcasting system should reflect the diversity of cultures in the country. Despite the official policies, a small segment of the Canadian population are critical of the concept(s) of a cultural mosaic and implementation(s) of multiculturalism legislation. Quebec's ideology differs from that of the other provinces in that its official policies focus on interculturalism.
Canadians have used the term "multiculturalism" in different ways: descriptively (as a sociological fact), prescriptively (as ideology) or politically (as policy). In the first sense, "multiculturalism" describes the many different religious traditions and cultural influences that together form a Canadian cultural mosaic. The country consists of people from a multitude of racial, religious and cultural backgrounds and is, at least in principle, open to cultural pluralism. 92% of the Canadian population aged 15 and older agreed that ethnic or cultural diversity is a Canadian value. Notwithstanding, critics argue it promotes the ghettoization of ethnic communities and hinders a cohesive national identity, while acting as a superficial "song and dance" that masks the marginalization of visible minorities and Indigenous peoples.
In the 21st century Canada is often characterised as being "very progressive, diverse, and multicultural". However, Canada until the 1960s saw itself in terms of English and French cultural, linguistic and political identities, and to some extent indigenous. European immigrants speaking other languages, such as Canadians of German ethnicity and Ukrainian Canadians, were suspect, especially during the First World War when thousands were put in camps because they were citizens of enemy nations. Jewish Canadians were also suspect, especially in Quebec where anti-semitism was a factor and the Catholic Church of Quebec associated Jews with modernism, liberalism, and other unacceptable values.
Asians encountered legal obstacles limiting immigration during the 1800s and early 1900s. Additional, specific ethnic groups that did immigrate during this time faced barriers within Canada preventing full participation in political and social matters, including equal pay and the right to vote. While black ex-slave refugees from the United States had been tolerated, racial minorities of African or Asian origin were generally believed "beyond the pale" (not acceptable to most people). Although this mood started to shift dramatically during the Second World War, Japanese Canadians were interned during the overseas conflict and their property confiscated. Prior to the advent of the Canadian Bill of Rights in 1960 and its successor the Canadian Charter of Rights and Freedoms in 1982, the laws of Canada did not provide much in the way of civil rights and it was typically of limited concern to the courts. Since the 1960s, Canada has placed emphasis on equality and inclusiveness for all people.
Immigration has played an integral part in the development of multiculturalism within Canada during the last half of the 20th century. Legislative restrictions on immigration (such as the Continuous journey regulation and Chinese Immigration Act) that had favoured British, American and European immigrants were amended during the 1960s, resulting in an influx of diverse people from Asia, Africa and the Caribbean. By 2006 Canada had grown to have 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 amounts. 16.2% of the population identify themselves as a visible minority.
Canada currently has one of the highest per capita immigration rate in the world, driven by economic policy and family reunification. Canada also resettles over one in ten of the world's refugees. In 2008, there were 65,567 immigrants in the family class, 21,860 refugees, and 149,072 economic immigrants amongst the 247,243 total immigrants to the country. Approximately 41% of Canadians are of either the first or second-generation. One out of every five Canadians currently living in Canada was born out of the country. The Canadian public as well as the major political parties support immigration. Political parties are cautious about criticizing the high level of immigration, because, as noted by The Globe and Mail, "in the early 1990s, the Reform Party" was branded 'racist' for suggesting that immigration levels be lowered from 250,000 to 150,000." The party was also noted for their opposition to government-sponsored multiculturalism.
Culturally diverse areas or "ethnic enclaves" are another way in which multiculturalism has manifested. Newcomers have tended to settle in the major urban areas. Since the 1970s, Canada has seen a shift in immigrant sources from Europe to Asia, Africa, the Caribbean, and South America. Most recent immigrants belong to visible minority groups like Blacks, Chinese, and South Asians, primarily settling in Toronto, Montreal, and Vancouver. Between 1981 and 1996, the proportion of visible minorities grew significantly in these cities. By 1996, Toronto had 42% of the nation's visible minority population, while Montreal and Vancouver had 30%. Across the three metropolitan areas, recent immigrants (individuals who landed in Canada between 1996 and 2006) are more likely to live in enclaves, as well as individuals who are dedicated to the preservation of their culture.
Urban enclaves have served as a home away from home for immigrants to Canada, while providing a unique experience of different cultures for those of long Canadian descent. In Canada, there are several ethnocentric communities with many diverse backgrounds, including Chinese, Indian, Italian and Greek. Canadian Chinatowns are one of the most prolific type of ethnic enclave found in major cities. These areas seemingly recreate an authentic Chinese experience within an urban community. During the first half of the 20th century, Chinatowns were associated with filth, seediness, and the derelict. By the late 20th century, Chinatown(s) had become areas worth preserving, a tourist attraction. They are now generally valued for their cultural significance and have become a feature of most large Canadian cities. Professor John Zucchi of McGill University states:
Unlike earlier periods when significant ethnic segregation might imply a lack of integration and therefore be viewed as a social problem, nowadays ethnic concentration in residential areas is a sign of vitality and indicates that multiculturalism as a social policy has been successful, that ethnic groups are retaining their identities if they so wish, and old-world cultures are being preserved at the same time that ethnic groups are being integrated. In addition these neighbourhoods, like their cultures, add to the definition of a city and point to the fact that integration is a two-way street."
Analysts generally agree that federal multiculturalism policy has evolved through three developmental phases: the incipient stage (pre-1971), the formative period (1971–1981), and institutionalization (1982 to the present).
