I will answer first.
For us, the issue is the upper limit. I wouldn't say that the motivation is slipping away, because the number of international students at our institutions is increasing. However, we are levelling off. CEGEPs are not growing fast enough to meet the demand or to allow them to build on the quality of the education they offer. They are trying to attract students from countries where young people don't just want university degrees, they also want advanced diplomas in technical or applied fields.
For us, that is a ceiling, and it is getting particularly thick.
