This is a container category. Due to its scope, it should contain only subcategories.

As known, Canadians are listed by their ethnic and/or the national origins or those of their forebears. Origins appear below as sub-categories. Note that many anglophones, who comprise the demographic majority of Canadians, lack published documentation of their specific ancestry (and therefore do not appear in this category's subcategories).

People who have acquired naturalized Canadian citizenship should be found in the sub-category Category:Naturalized citizens of Canada while those living in Canada without (confirmed) Canadian citizenship are found under Category:Expatriates in Canada.

See also Ethnic origins of people in Canada, as well as Category:People of Canadian descent for the opposite category.
