Fewer bears, more hyenas in Toronto, but that's for PA.Where's that? Seems like it's legal to use on bears anywhere out West.
Problem could be the folks who try to buy it to use on people?
If you're going to say something like can't carry it in Toronto I'd guess that's probably because bear attacks have really dropped off there.
Pepper spray is a prohibited weapon everywhere in Canada. Bear spray isn't, and here is where the legalisms enter. Bear spray is legal provided it is for the purpose of protection from bears ( and similar wildlife) in a wilderness setting. Otherwise, it's a prohibited weapon and all the other provisions regarding weapons, like carrying a concealed weapon, apply and you'll likely be charged under section 90 of the Criminal Code.
Warning to the uninitiated. I never used bear spray so on one of my earliest trips to the nahanni, which is grizzly country, I decided to train with a canister because everyone knows you have to train, right? Found a nice target tree and practiced. Like a moron. What I didn't know is that on the mucous membranes of a bear it might discourage bears mightily, but on a tree it attracts them mightily because it's like hot & spicy night at the local restaurant for them.
