Most information presented in Demographics is based on the 1991, 1996, 2001 and 2006 Census of Canada. This data is collected by Statistics Canada every five years. The census of the population provides a reliable source for describing the population and dwelling counts not only for Canada but also for each province and territory, and for cities or districts within cities. The census also provides information about Canada’s demographic, social and economic characteristics.

By law each household must provide the information requested in the census, and by the same law Statistics Canada must protect the confidentiality of the personal information provided by respondents.

The census enumerates (counts) everyone living in Canada. Included are Canadian citizens, landed immigrants and non-permanent residents and members of their families living with them in Canada. Non-permanent residents are persons who hold a Ministerial permit, student authorization or employment authorization, or who claim refugee status.

The most recent Census Day in Canada was Tuesday, May 16, 2006. For more information about Census 2006 release topics and dates, visit Statistics Canada's website at http://www12.statcan.ca/english/census06/release/index.cfm
