Census returns after 1916 are in the custody of Statistics Canada, not Library and Archives Canada. The records are closed under the Statistics Act and the Act to Amend the Statistics Act [www.parl.gc.ca/common/Bills_ls.asp?lang=E&Parl=38&Ses=1&ls=S18&source=Bills_Senate_Government]. Under the legislation, when 92 calendar years have elapsed since the taking of a census, those records will be opened for public use and transferred to Library and Archives Canada.
