I would really be careful if you are Canadian and wanting to apply to a DO school, simply because it would be extremely difficult for you to go back to Canada. (Yes, yes, yes, it can be done and there are actually 12 DOs practicing in Canada but for the most part it IS difficult and realistically you will be looking at living and working in the US for the rest of your life, not that that's bad of course.) Even if you do end up getting back to Canada, be prepared to explain your degree to EVERYONE. And yes, this includes other physicians, nurses, etc. When I was applying two years ago I asked my family doc what he thought of osteopathic doctors. And his reply was that he thought they were quacks and to stay away from those schools. Obviously he didn't know what he was talking about but he also didn't know better so it was forgiveable.
I think KCOM, AZCOM and some other privates take Canadians. I know KCOM does for sure because I asked them about it two years ago (but never ended up applying). Good luck.
