My grandfather grew up on a farm in northern Alberta in the 1920s and my grandmother's family lived for a time on a farm in Manitoba. There were a lot more Jewish farmers in Canada then America. It's because the Canadian government forced many Jewish immigrants (and other immigrants) to live in small rural northern communities, especially in Manitoba and Alberta (and for a very short time Cape Breton), to try to settle the north. The plan in general was a huge failure, but you've got a couple small communities of farmers in parts of rural Canada which were, or still are, entirely Jewish.
Didn't the Bronfman family start their liquor business in Alberta? Perhaps Saskatchewan?
