In general, I don't think there's much to worry about if someone within city limits tries to practice with a below 500fps airgun inside their home, or even backyard if its very secluded. However, a few comments are in order in regards to suggesting that anyone who's worried about doing this in Toronto is one of the "sheeple."
A fellow gunnut who lives close to me told me of an incident where a neighbour called the police over someone else who was using an air rifle on some pesky racoons that were troubling him. Apparently the police response was quite considerable, and while shooting racoons is far more noticable than what we've been discussing, I suspect that the woman who called would have made a similar fuss and gotten a similar reaction had she simply seen people using an airgun.
The other factor to keep into consideration is the possible ramifications for a law abiding, licensed gun owner should the police be called over being seen with an airgun. If you're just some typical Torontonian discreetly shooting an airgun with your son or daughter, probably the worst that will happen is the loss of a Canadian Tire airgun and maybe the equivalent of a parking ticket. But if you have firearms, especially for those of us with more than an old shotgun, Cooey or bubba'd Enfield, a call over being seen with an airgun offers a perfect opportunity for the powers that be to put your guns on a display table at the next day's press conference, and good luck getting them back. And with things as crazy as they are in this city, I wouldn't be surprised if a school teacher who overheard that one of their students was shooting an airgun at home won't try to get the authorities after their parents! Hopefully it would come back in their face and make them look like an incompetant idiot, but you never know.
Sure, this is all very silly, since I'd say that if the city feels that it has the right to regulate something as innocuous as firing an airgun in your basement, they may as well interfere with practically everything else. This might even be a good area for a civil liberties case, since I think it's difficult for the city to justify this beyond their simple attempt to control what people think of guns and shooting. The public safety arguement certainly cannot hold. That said, I think that it will play into the aniti's hands and can give a decent gun owner much grief as they sit through a year of awaiting a court date, wondering if they'll ever see their Garand, Mausers, pistols, etc again.... These people are more than happy to drive us nuts with technicalities and treat us as criminals the minute we violate the most obscure rule.
There's lots of exceptions to the worst case scenario that I'm portraying here, but sadly my hometown has become the epicentre of idiocy.
Cheers,
Frank
PS. I thought I saw a picture of an airgun competition in a hotel in Toronto in the latest CSSA magazine. Along with the comments, "we hope the Mayor didn't notice...." Perhaps they might have some insight here as to whether such a bylaw can withstand a challenge?
