New Brunswick is the only other bilingual province though it would be nice to see a Gaelic revival in Cape Breton and Newfoundland
Basically, if you go far enough back to get multiple French-majority provinces, you've butterflied away all of modern history.Let's say that Canada had more than one province speaking predominantly French, and not just Quebec (or Quebec is split into two or more provinces). How would the Quiet Revolution have played out? What effect would that have had on the liberalization of the people from the Catholic Church's influence? On French-Canadian separatism?
There was still, at the time (and there still remain), large-ish french minorities in Ontario and Manitoba, too, although not as large a minority as the Acadians and they pretty much spent a lot of the 70s-80s fighting to have the right to set up their schools in French in the two provinces...
And then you could see the Michif and other groups (IOTL, it took a while for a number of native groups to realize how fast linguistic assimilation on the reservations was going)
