Seeing that you are a fellow U of A med student, I thought I might mention that because the residency is in the US, you may have a hard time getting your CFPC certification and getting a licence to practice in Canada. If you would like to do family med and want to do medical missions, i would suggest simply doing a canadian residency and doing some mission work during your residency.
But you should first focus on getting through med school first.
See ya on the 27th (maybe).
