Contrary to what the media leads on, the US isn’t a free for all on firearms purchasing.  You as a Canadian, unless you are a Resident Alien with proper Documentation, can not purchase a firearm in the United States.  Someone can not legally purchase/pick up from an FFL dealer on your behalf either.  This would be considered a “straw purchase” by the BATFE and it comes with a vacation at the correctional facility.  So there is no way to legally acquire and carry a firearm to you.  Contact 
@BRICKBURN as he imported a 375 that he won a couple years ago and it seemed pretty painless.
Good luck Cam!
