Don't try the airsoft guns they WILL be confiscated. Pellet guns should be fine but why not get one through a Canadian airgun store (I'm pretty partial to the Anschutz 10m air rifle line myself)? You'll at least get a warranty that will be honoured and by the time the smoke clears you'll be paying more getting it somewhere else than going to CT or whatever to buy.
Also do you want parts or guns? Parts will be fine except anything restricted.
