The problem was created by Provinces cutting funds to universities and education in general... Universities made up the shortfall by using International Students which was a Federally enabled escape valve.
This has been the game of mostly conservative Provincial Premiers; cut everything and blame it on the Feds.
I do feel for some of the legit universities but from what I see, the vast majority of the money milked from International Students did not go to improve the level of education (barely has moved in the last few years) and mostly went to "Mall universities" which are borderline a scam, all stamped and approved by the Provincial gov.
