It would be nice if you can back it up wit some hard evidence, or is it just some speculation of yours based on some loopholes. Either case, can you provide some more concrete?
It would likely depend province to province. I don't know any provinces that would allow it but i don't know ALL the provincial regs.
He's quite right in that antique handguns can technically be taken into the woods. Calum has done a lot of homework on that, so talk to him if you want the details.
However - in bc for example the regs expressly forbid ANY hunting with a handgun or any gun 'designed to be easily fired with one hand". And by their definition of 'gun', that includes pellet guns even tho they're not considered 'guns' by c-68.
So while federally you might be able to take a handgun hunting, legally you would not be allowed to hunt with it based on provincial regs in bc.
