Whoah, nice collection dude. Too many armalites for my tastes but impressive nonetheless. A freind of mine would shit his pants over that pulse rifle though!
Getting into airsoft in canada is 'kind' of tricky. As you cannot bring any of those into the country without risking confiscation, you have to buy new. First you have to verify your age with a local representative:
http://www.airsoftcanada.com/forumdisplay.php?f=108 . Set up a meeting with him, present government ID and within a few weeks you will be granted access to the private retailer's and the classifieds to buy yourself your new gun. Keep in mind, prices up here are atrocious and new guns can be pretty expensive, but I doubt you'll be working up a collection like that up here anytime soon. Haha.
Anyway, good luck! Hope you enjoy it here.
