Hey MPH1103,
Most of the programs you applied to will be very similar. I put McGill and U of T (epi) as my top choices because I really want to do epidemiology, and both these programs are really focused on it. Depending on what stream you applied to at U of T, it would probably be very different from a more general program like Queen's. But then there are other things to consider like whether or not they give any scholarship (I haven't heard of anyone getting a scholarship so far though! So disappointing), how much the tuition is, if you'll have to move far from home, how established the program is/how long has it been around? Things like that. Honestly though, I think all the universities give a very high quality of education so don't stress too much about it Most schools post the required courses so I looked at those to get an idea of what the program will be like.
