The 1921 Census of Canada

is finally available, though not yet indexed by name.

It is now available free of charge at ancestry.ca (but without index by name, so you need to know where your ancestors lived in order to readily find them). According  to John Reid of Anglo-Celtic Connections (who always has the latest scoop on anything related to the LAC), it will be available at ancestry.ca with “a geographic index only,” but “Ancestry [ancestry.ca] is working on a name index to be available to their subscribers this fall, and made freely through LAC after three years.”
