To increase your chances of getting a visa, you should have the first year of study in Canada paid for, have money to live in the new and expensive country, and, of course, be able to buy a flight ticket, undergo a medical exam, etc.
We recommend having at least USD 20,000 (but better more!) if 1 student is going to study. And add USD 5,000 for each additional family member who will accompany you.
