Canada

Quebec already set a precedent that Provinces can theoretically vote to separate. The Bloc Quebecois in the 90s held votes, and the claim then was that a simple 51% majority on the referendum would've triggered Quebec into declaring independence from Canada. The blocs remained a staple in Canadian politics ever since, historically promoting "Quebec First" and separatist values the whole time, with tons of support from people in Quebec -- one of the big surprises with the US rhetoric, is that Quebec is suddenly seeming more 'pro Canada', even while still electing a party who's roots are separatist. Canada's a federation of provinces, so it's theoretically possible for provinces to leave.

If Quebec can do that, there's no reason to think that other provinces can't do the same. And if Alberta were to hold such a referendum, and the vote showed 51% in favour of 'leaving' -- be it through semantic shenanigans on the phrasing of the question, or overt election manipulation aided by people like Musk -- it's unclear how the rest of Canada would react. Even more, if they did that, and Canada didn't let them "leave", the US could take that as a justification to help "free" the people and oil of Alberta.

Individual towns and regions might try to separate -- in the Quebec referendum, there'd been talks of the northern parts of QB wanting to stay in Canada. Practically though I don't imagine that'd happen. The division of powers between provinces and federal governments, and the authorities given them, are fairly clear cut. Towns and regions sorta just pop up at resource hubs within the province, and aren't as clearly demarked in terms of self governance / "the big" items for a nation. Again, we're a federation of provinces, but provinces aren't a 'federation' of cities.

Have a look through their comments. Hardly the first shitty take they've had
