For OVC at Guelph, Canadian applicants have to take the MCAT.

Not sure about UPEI, WVCM or UCVM exactly, you can check out their sites. I don't believe any other schools require the MCAT (just the GRE) and the prereq courses may differ. There is also Universite de Montreal if you're fluent in French (only taught in French).
