Not sure about the visa issue. I don't believe it's too difficult to get a student visa to come to Canada but i'm not an expert on the subject. Best bet is to contact the school and find out what the process is like.

The three schools you mentioned are the big ones in Canada along with Queens University. From what I gather they are the top tier schools in Canada. When you look at the second tier schools you'll be looking at UBC and McMaster University among others. It also depends on what you plan on doing post-MBA.

Thanks - I will look into those schools. I haven't really decided what I want to do post-MBA, but I'm considering going into brand management, either in wine or organic foods. I haven't found any Canadian programs that focus on these, though.

Good news, everyone! I found out some information about getting a student visa in Canada. For Americans, the process looks exceptionally simple, requiring pretty much what you would expect:

Proof of acceptance to the school
Proof that you've paid your tuition
Medical insurance coverage forms
Proof that through your savings and financial aid you can live in Canada comfortably while you're in school.

I don't think this visa allows you to work while you're there.
