Check out AACOM's reports on total enrollment and look for the number of students at each school that are considered "Nonresident Aliens". This is an indicator of whether the medical school accepts Canadian or non-US citizens. Be advised that individual school admission decisions change every year. It is best to email individual schools to see if they accept Canadian or non-US citizens.
