Quebec already has laws on the book that make them de jure separate from Canada by claiming the Provincial governments have powers that supersede Ottawa's authority [0]. Nobody really talks about it beyond a, "lol no". It's the foundation of a crisis.

So Canada is already fractured. And there's a strong chance Québécois offer support of Alberta and Sas succession. Perhaps there will be some reciprocity and all three provinces leave Canada at the same time.

Which leaves western Canada in a bit of a pickle.
