<p>I’ve got to agree with whenhen. Unless you’re at the point where you’re taking advanced sophomore and early junior-level classes in high school, any of the math departments that you mentioned will be sufficient for your needs. Furthermore, there’s unlikely to be big differences between them when it comes to getting into graduate school (whether in Canada or the United States) as long as you do all of the things you’re supposed to for grad school (write papers, get to know professors, research experience).</p>
<p>Personally I would save my money and choose one of the Canadian universities, especially if you have the option to go to UToronto.</p>
