Why not simply go to Schulich School of Business website and see how they’re ranked. Top schools in Canada are (in no particular order) Ivey, Schulich, Rotman, and Queens. There are subtle differences between programs (overall quality of education, faculty, etc), but what separates these schools from the rest of the pack in Canada is how much networking and exposure you get (better program = better candidates = networking). Also, look at the number and quality of recruiters going to each school - that should give you some idea about where to go 
Schulich and particularly Rotman are the way to go if you are thinking of a career in finance. Schulich is also your top choice if you are not sure where to go (due to the number of different areas of specialization).
Get it cheap from McGill and then move to the US Best reputation south of the border !
Although Schulich and Rotman are probably superior, like the previous poster mentioned, in the States, McGill has a better reputation.
