I could swear I came across the 1921 Census of CANADA a few days ago -- on this website (ANCESTRY.com).
I dismissed it because I do not know the provinces, to say nothing of the cities, etc. It was not indexed, but offered a page-by-page search (as was the USA 1940 before indexing).
Now, I have some info that might help me to use it - but cannot find the database.
As I was NOT seeking it, how could I have simply imagined this?
