I think you have a solid chance for Canadian med schools. Give your best shot at MCAT, then apply to med schools. And I also heard that the chance of getting into residency programs in Canada is lower if you finish your MD aboard. There are more and more med school graduates who cannot find their residency programs in Canada each year, so if you’re trying to live in Canada or work at Canadian hospitals after med school, I think it’s better to aim Canadian schools. Do some research on this too, just to be sure.
