I also know nothing about Canadians politics. I don't think all separatist/independence movements should be dismissed out of hand, but this seemed to be Chud magnet.
Though in all these situations, "voting for independence" is the easy part. It's the details of the divorce agreement that matter, and can't be captured in an aspirational vote.
Nobody really knew what they were voting for with Brexit, for example, which was its own kind of separatist vote. It could've allowed for "Norway" or the shitshow they ultimately agreed to.
