Although by 1921 the Canadian government considered all persons from the Baltic provinces to be Russians, it is known that there were some Latvians living in Canada in those years, because in 1961, 379 Latvian indicated that they had arrived in Canada prior to 1921, and most probably left Latvia after the 1905 Revolution.

Many of these Latvians worked in the agricultural areas during their first years in Canada, but soon settled in cities.

[citation needed] In 1991, the largest populations of Latvian Canadians are in Toronto, Vancouver, Hamilton, Ottawa, and Montreal, Quebec.

On a parish basis they are connected to the larger Roman Catholic Church in Canada.

In the Toronto archdiocese is The Association of Canadian Latvian Catholics, founded in 1949.
