Canada

I don’t understand how what once was rare in foreign tuition, then was a cash cow, and is now limited (but not eliminated) is now responsible for the total collapse of some schools.

They overextended themselves during the years the money was coming in, most likely, and now can't afford the remaining payments on new buildings or equipment or the current staff salaries or whatever without the extra financial support. (There's also the possibility of outright embezzlement having taken place, as at Laurentian U, which ended up axing a couple of programs.) Wikipedia suggests that Algonquin's been building or renovating a fair amount of stuff on their main campus in Ottawa over the past fifteen years. If they took out loans to finance some of it, it would make sense that they're short on cash now.

I don't either. I do know med schools are definitely held up by the giant fees the international medical students pay, so it'll be interesting to see what happens to them due to them being banned, aside from the Saudis whose government pay them to be here apparently and probably will always find a spot here. Apparently already 88 percent of med students are Canadian born so they say the change won't be much, but honestly I work in a hospital and it feels like almost all of the students at whatever level are international.

Really it would make more sense to me to fix the family doctor problem in Ontario to provide a bridging program for doctors who already live here but aren't able to practice because they don't qualify, a lot of skilled people being wasted that way, or having to do dumb shit like a psychiatrist I know who had to practice as a GP in rural Nova Scotia for five years before they'd let him be a psychiatrist here in Ontario. That's a waste of talent that already exists here that would be a win for everyone, rather than training a Canadian GP who will get burned out on the low pay and dogsbody work, and quit and go be a hospitalist.
