All this depends on one key thing, will the students WANT to keep coming?
I don't want to say yes or no, but I am sure Canada will have to pivot to African countries or failing countries like Egypt or Pakistan significantly because cat's out of the bag in India.
They will make likely make PR easier. Canada does not get expats because expats have a plethora of choices. Only PR hopefuls come here.
Looks like Canada pissed off China some time back so they had to pivot to India to make up the international student loss and now Canada decided to pick a fight with India too.
