You don't say, "colleges catering to foreigners have popped up in strip malls and temporary buildings, most notably in the Toronto suburb of Brampton.". The NDPLiberal government eliminated the maximum 20 hours part time work limit for students and now college aged entrants to Canada are able to enter as a "student visa" (does that mean a real college/university or a bogus one?) and work 40 hours at Uber deliveries, 60 hours at a Fiat Chrysler auto factory line, etc. Meaning, there's barely any hours left in a day to study or in other words, where's the "student" in "student visa"? Canada's immigration system needs a serious review, inquiry, study and overhaul.
