Dear umr,
Based on the limited information in your post, you have a competitive GMAT score for most MBA programs and evidence of leadership potential. However, you did not indicate what your professional experience has been since college nor your career goals post-MBA, so it is hard to comment fully on your chances at any program. Assuming you have gained quality professional experience since college and will have a strong set of essays and recommendations, I do think you have a shot at Rotman and Schulich, as well as some other top MBA programs. The ultimate decision at any program will be based on a holistic evaluation of your application, so use every component to make a compelling case for your admission. While your GPA is a potential weakness, your solid GMAT and a successful professional track record can mitigate that component.
Good luck,
Lisa
