Canadians are the people who are identified with the country of Canada. This connection may be residential, legal, historical, and/or cultural. For most Canadians, several (frequently all) of those types of connections exist and are the source(s) of their being considered Canadians. The majority of the population is made up of Old World immigrants and their descendants. Following the initial period of French and then the much larger British colonization, different waves (or peaks) of immigration and settlement of non-aboriginal peoples took place over the course of nearly two centuries and continue today. Elements of Aboriginal, French, British and more recent immigrant customs, languages and religions have combined to form the culture of Canada and thus a Canadian identity. Canada has also been strongly influenced by its linguistic, geographic and economic neighbour, the United States. Canadian independence from Great Britain grew gradually over the course of many years since the formation of the Canadian Confederation in 1867. World War I and World War II in particular gave rise to a desire amongst Canadians to have their country recognized as a fully-fledged sovereign state with a distinct citizenship. Legislative independence was established with the passage of the Statute of Westminster 1931, the Canadian Citizenship Act of 1946 took effect on January 1, 1947, and full sovereignty was achieved with the patriation of the constitution in 1982. Canada's nationality law closely mirrored that of the United Kingdom. Legislation since the mid 20th century represents Canadians' commitment to multilateralism and socioeconomic development.
