Heh...these types of questions always make me laugh a little. With no offense to the one who askes the question of course.
The only real answer to your question is whether you
think it's worth it. The ones who are in the sport already obviously think it is indeed worth it. Airsoft in Canada is what it is and the decision to jump in or not is entirely up to you. If you don't think it's worth it, no one's holding a gun to your head...on the other hand if you do decide to join in on the sport, it's very likely you'll have a few guns pointed in your general direction
