It wouldn't mean a fucking thing if you could own a gun. You're not even allowed to carry a big stick if you're intending to use it to defend yourself in Canada. It doesn't even matter if you use it for its intended purpose. Possessing any object for the purpose of self-defence is illegal in Canada. If there is a firearm (or a sword or a bat) in your home and you intend to use it on an invader, then congratulations because you've committed thought crime.
Sure, it's worthwhile to ensure that we are allowed to possess firearms, but the root is much deeper than whether or not you're allowed to have a gun at all. If you use a gun to defend yourself, you are going to prison no matter what.
