The province of Ontario pays for Catholic schools but not Jewish schools.
However, the provinces of Quebec and British Columbia pay about half the cost of Jewish schools. (Basically, they cover the cost of the government-mandated secular curriculum.) I visited British Columbia twice this past summer and was very impressed by the small community in Vancouver. It has a Chofetz Chaim yeshiva with some very impressive rabbis. The community in Victoria was tiny but very friendly. In other respects they are expensive cities but the major cost of Jewish living is the schools. And the weather is mild and the natural surroundings are beautiful.
