What Library and Archives Canada Holds
Library and Archives Canada (LAC) is the national memory: censuses (1825–1931, free and searchable), immigration passenger lists, military service files from the First and Second World Wars, naturalization records, land grants, and the documentary heritage of the federal government itself.
Anything unpublished can be requested: LAC material moves through access-to-information and archival request processes, and much of the genealogy core is already digitized and free. The links below go straight to the main collections and finding aids.
