UTM vs UBC Vancouver vs McGill

I am a high school senior who applied to and was admitted in to the University of Toronto Mississauga, the University of British Columbia Vancouver and McGill University and I am having the toughest time deciding which school to go to. I was not really aware that UTM was a sister campus and ergo not as prestigious as UTSG so initially, I really wanted to go to UTM but now I am seriously doubting if I should go. BTW I am majoring in Biology at all three schools.

I am basically just super worried because I go to high school in the US (but I am a Canadian citizen) and I plan on going to grad school or med school in the US so I feel like I have to go to a competitive undergraduate school since Ill be in Canada…if you smell what im cooking :slight_smile:

Please leave suggestions and reasons why I should go to either McGill, UBC or UTM!!

Thanks!!!
