Even if the bill is voted, I don't think it would directly affect us. It would definitely set a precedent, which is bad for all airsoft players in North-America though.
IF the bill passes, it doesn't mean that Canada will look at this and say "Hey look, Calif did this, we'll do the same tomorrow!" If there's really people in the government looking into the airsoft situation in Canada, they'll probably wait a bit and see the costs/results to such a law. Chances are they realize it's not really worth it. Where the problem lies is that they still will be able to use this as a lever for their own schemes and machination to bring down airsoft in here though, which is bad, obviously.
Well, as long as they make the Pink guns full metals anyways with the same quality... let's just say Krylon's shares will go up a bit
