We Canadians are very lucky to have 6 really good business schools. I don't think its fair to rank them, they're all on par with one another IMO. Schulich, Ivey, Rotman, Sauder, Queen's or Desautels are all very good academically. That being said, it is important to choose a school that's in line with your future goals. I chose McGill because I intend to move around within Canada and internationally after my MBA and McGill's name resonates all over the world. For people who want to work in Ontario, Schulich/Queen's/Rotman/Ivey might be more appealing while Sauder might be more appealing for people who want to work in western Canada. It is natural for the majority of graduates of a certain school to land a job in the same province as the school they attended. I think it really comes down to where you want to work and what are your future goals.
Bottom line - you can't go wrong with any of these schools and congrats to all recent admits !
