Not greater number of guns, greater availability of guns. This is generally reflected in numbers, but it isn't the same thing.
Availability to the right people is key - decent & lawful people as opposed to violent criminals. There is value in a background check - there's no need for license expirations, Gov't lists of guns or other arbitrary rituals - Safety is covered in S86 of the CC. C68 is convoluted & dangerous legislation designed to ensnare and criminalize the otherwise lawful, but unwary gun owner - the sooner it goes, the better. Is it reasonable to believe that Canada only has 1.8 decent & lawful people out of say, 20M of legal age, worthy of gun ownership? Of course not. Violent criminals are very few.
