Pistols are banned. Rifles and shotguns are supposed to be registered.
Evidently as in England, self defense is not permitted.
Self defense can still exist in Canada via pistol...You just need some imagination.
After killing the dangerous intruder, take the body out to the local highway and dump it....Hurry back to complete a good nights rest.
Leave the police out of the equation so you don't spend the rest of your life in a cell.
