Actually LAC (Library Archives of Canada) started using Ancestry for transcribing 1921 census. The format is LASTNAME, first Name on original forms as with USA. I think that’s why Ancestry has the census on their site and Family Search doesn’t. Money talks.
Will see what happens 2023 when fingers crossed, 1931 Canaans census is released. Between now and then, rules may change as they did with other records. “Privacy because people live longer” was excuse.
