I think I would have to agree with Ca(PO4)3OH in that it would probably be harder. My impression is that even if you are from Canada, that makes you a FMG, which makes it a lot harder for you to get a US residency. I've heard from one of my classmates (who's going into medicine) that's from Canada, that if you go to med school in the US though, then there's no difference in terms of your application if the hospital/university supports the type of visa that you need. If you don't go to a US med school, then there's no difference between a Canadian and someone from someplace like Fiji (not that there's anything wrong about Fiji). The best advice would be to keep what you're doing in terms of research, rock your third year clerkships, and work your ass off during the away rotations. The places where you do your aways will probably be your best bet in terms of matching...so you would probably want to pick those places wisely.
actually thats not true..
being a grad from a canadian school you are NOT..... absolutely NOT considered a FMG... it does not put u in the same boat as being from a school in fiji.. Canadian schools are accreditated by the LCME the same body that accredits US schools...
being a grad from a canadian med school is the same as being a grad from a US school... the ONLY problem you will have is obtaining a VISA to do ur residency in the US.... if you want to remain in the US after residency... then u want an h1B visa.. u have to get the hospital/university to sponsor you.. VERY DIFFICULT... if u want to go back to canada then a j1 visa will do.. BUT make sure your training in the US will be recognised in canada.. because alot of times canada will say you need an extra yr and lots of red tape like that...
a FMG is someone that goes to a school that is not accredited by the LCME.. all the med schools in the US and CANADA.. and ONLY med schools in US and Canada are accredited by the LCME... any other school u are considered a FMG.. if u are US citizen in foreign school (incl Caribbean) or if u are a foreigner in a foreign school u are a FMG... in which case you will have even more difficulties obtaining an ortho residency because the majority of the programs will not even look at ur app as soon as they see FMG
