Ancestry has acquired the 1921 census of Canada- YAY!!! It is NOT YET INDEXED but if you feel like scrolling through pages where your ancestors lived, you might find them. I managed to find my paternal grandparents living north of Barrhead, Alberta this morning after consulting a grid map for Townships and Ranges for Alberta. Took me awhile, but I also re-read my notes which helped to pinpoint where they were living in 1921. My grandfather moved from Lennox and Addington County where he was born about 1885, between 1908 and 1911 to Saskatchewan and then to Alberta.
