I think most Canadian colleges and universities are not worried about going broke, but yeah they need international students for that reason. Compared to Taiwan, or even the US, Cansda is very attractive to international students for lots of reasons
Definitely it is a business, and Australia as well, there is competition for these international students who pay DOUBLE what local students pay in Canada. But this has been the case for a long time
Occasionally schools will fail and close, but nothing like what is happening and will get worse soon in Taiwan
