With international students, it's a more complicated situation because while they do work.... I remember the days when our students at Carleton University could work a maximum of 10 hours per week, and it had to be on campus. At that time, there were clear benefits to that program. The international students at the university level pay a remarkable tuition. I think it's three, four or sometimes five times as much as what a domestic student does, so it is very important to these institutions and, arguably, to the Canadian economy.
The problem is that once you say to the students that they can work 25 hours per week off campus—which is a big difference from 10 hours per week on campus, as it used to be—and that they can work as many hours as they want when they're not in the teaching semester, suddenly you're starting to have a big labour-market impact, given the number of students involved.
I think it was more of an Ontario problem at the private and community college level, to be fair to institutions across the country.
You mentioned commercial fisheries. I think there is an open question there as to whether you would treat those the same as farming. My preference would be to have very targeted temporary foreign worker programs.
