Take Australia out of that list. Heard its even worse than CanadaInternational students are an industry here, and the biggest draw for them is applying for PR. They won't risk alienating that source of income.
Canada is nice, but all things being equal, most who are actual, legit students would likely prefer the U.S, UK, or Australia, if immigration was not a factor.
So if that's not an option, expect intakes to drop dramatically.
