I think if you can get a univeristy offer, this is gona to help your migrant application. however once you get permission of migrant you might pay the same amount of tuition fee as canadian does. if you apply as oversea student (from china), i guess you will have to pay more than the canadian does. so it really a kind of compromise. since I never been to canada and this is just a personal view. hope some senior or knowledgable people will turn up who is gona to help you.
