So according to this article Canada has seen an increase of 500,000 foreign students.<p>Assuming a highly conservative $20k in annual tuition fees (the cheapest decent US public college will run you at least $30k for 2 semesters in tuition alone, never mind fees, living costs, etc), that’s about $10Bn in additional annual revenue with about 4 years locked in, every year.<p>And that’s just tuition. It doesn’t include living costs, the fact that many students might have friends and family visit, they will contribute to the academic and research programs at the university, and will graduate and almost certainly have a much higher output than what they will consume, being, almost by definition, more highly educated than the average Canadian.
