The number of immigrants from European countries other than Britain or France increased dramatically in the first half of the 20th century, from 9% in 1901 to 20% in 1941, mostly from Northern and Western Europe in the earlier years, and Southern, Central and Eastern Europe in later years. The Canadian Immigration Act of 1952 established the rights of admission to Canada. It was amended in 1962 and again in 1966. European Canadians make up approximately 76% of the Canadian population.
Statistics Canada produces statistics about the Canadian population, including composition by ethnic self-identification. Those of European origins are divided into several subcategories: British Isles, French, Western European, Northern European, Eastern European, Southern European, and Other.
