I want to apply to a Canadian grad school that is of particular interest to me. I did pretty well, I have a very high GPA (overall and math wise) on a 4.0 scale. Do I apply for PhD or do I apply for masters? What are my chances of receiving any aid in terms of a TA-ship? How exactly does grad school work in Canada? Thanks in advance for your replies. EDIT: Why not just mention the school, it's Waterloo's Applied Math program.
