Ivey and Smith are the best in ON. If you can get a bump somewhere, you might have a chance for Ivey AEO. For Smith, once you exceed the 87 cut-off, all they care about is the quality of the supplementary which is where you include the ECs to differentiate yourself from other applicants. Yeah, Laurier is decent, but probably considered tier-2, and Rotman is alright but they accept way too many students so the class sizes are huge and also because they print out so many degrees, it'll be devalued compared to the other more competitive, tight-knit programs.
