Canada Censuses
The Church of Jesus Christ of Latter-Day Saints has access to the 1881 Canadian Census and it is definitely the easiest way to search this census. In the Prince Edward Island site I've been using to search the 1841, 1891, and 1901 Censuses, all the members of a family living on the same lot of land are listed together and it's hard to separate each individual family. I've seen 25 MacAuslands all living on Lot 13 and I'm not sure which children belong to which adults. There is no order to the names. On the other hand, the 1881 Census on FamilySearch separates these people into their respective families and makes it easier for researching genealogists.
If you're like me, you've had a hard time finding places to search the Canada Censuses, so here are a few sites that list websites to use.
