In reality Canada prohibits handguns from entering the country and they ban pepper spray, at least in Ontario. I cruised my sailboat in Canadian waters in the northern reaches of Lake Huron (the North Channel). There had been reports one year of bear attacks, so when I checked in with Customs and Immigration I asked about protection from bears. When I asked about pepper spray, they said it was illegal but suggested “bear spray.”
I asked what was in it, the answer was pepper. Go figure.
Gotta' love the government. Probably the same thing... the factory just uses a different lable to make it acceptable in another country.
