This is a page of resources for the province of Ontario, Canada.
Ontario (Canada West) joined Confederation on July 1, 1867, one of the original 4 provinces.
Prior to that, the Act of Union created the Province of Canada in 1841, which consisted of Canada West (Ontario) and Canada East (Quebec).
After the 1941 Act of Union creating the Province of Canada, a decision was made to enumerate the population to determine parliamentary representation. This may help explain the emphasis on specifically enumerating the numbers of immigrants from England, Ireland, Scotland, France, and the USA.
The second census of the Province of Canada.
Library and Archives Canada has a single searchable database for Canada East (Quebec), Canada West (Ontario), New Brunswick, and Nova Scotia.
The third census of the Province of Canada.
Like the 1851 Census above, Library and Archives Canada has a single searchable database for Canada East (Quebec), Canada West (Ontario), New Brunswick, and Nova Scotia. The census of Canada West was begun on January 14, 1861.
A rich, deep site, staffed by volunteers and like one-stop shopping for Ontario genealogy hunters.
It’s like going to garage sales, genealogy-style. Enter a family name and see what comes up! I tried a couple of my Ontario old family names and got 1000 hits, the first 20 of which were newspaper announcements. I can see a few Sunday afternoons being spent on this site.
