I'm an American thinking of going to college in Montreal to save money?

Chances are you'll have to pay international tuition rates. Most states offer financial aid which can nearly cover the cost of tuition. For example, when I was in college, I was given over $13000 in aid every year even though my family makes a significant amount of money every year. The good thing about grants is that you don't pay them back, and they are not dependent on grades.
