Why did Canada adopt multiculturalism as an official national policy in 1971?

Canada adopted multiculturalism as an official national policy in 1971 to provide support to various ethnic groups and assist individuals in participating fully in Canadian society.1

This policy shift occurred in the context of a changing demographic landscape. Following World War II, Canada experienced large-scale immigration, particularly from southern Europe, which significantly increased the number of Canadians who were neither French nor British in origin. As the proportion of Canadians of British descent declined, the country’s traditional social structure and political culture began to evolve.2

By establishing multiculturalism as an official policy, the federal government sought to acknowledge the contributions of diverse cultural groups and promote inclusion, moving away from the traditional liberal image of a "melting pot" toward a model where diverse members of society can maintain their particular identities while remaining integral parts of the collective. This approach serves as a response to cultural pluralism and a means of addressing past exclusion and discrimination faced by minority groups.13
