Saguenay isn't exactly an area rife with airsofters or age verifiers, so I can understand that not really being an option...
That being said, your options for airsoft guns are pretty slim in Canada outside of the AV areas of this forum. The only thing you're likely to get are clear guns from Cdn Tire, Wal Mart, or sometimes from army surplus, paintball, or outdoors stores. That's what's available, unfortunately.
That being said, you're obviously not looking for a spring pistol to actually play airsoft games. That would be pretty useless. If you're looking for something to shoot for target practice or a showpiece, then a pellet gun is probably a much better option than airsoft.
