How gun control works: Canada keeps guns somewhat accessible to the general population, but maintains major restrictions on different types of guns, who can buy them, and how they're purchased. The result is a system that looks like a stricter version of the US so some sort of firearm ownership is still a possibility, but not something that's done very easily.
Canada puts guns into three categories: prohibited (most handguns that have a short barrel or are .32 or .25 caliber, fully automatic weapons, guns with sawed-off barrels, and certain military rifles like the AK-47), restricted (some handguns, some semiautomatic rifles, and certain non-semiautomatic rifles), and non-restricted (regular and some military-style shotguns and rifles). The general idea is that more dangerous guns face much harsher regulations and restrictions on purchase, ownership, and storage.
Prohibited guns are, as their name implies, prohibited, but people who obtained and maintained a registration certificate before they were banned in December 1998 can keep those specific guns. All restricted and prohibited firearms must be registered, but non-restricted guns no longer have to be registered after April 2012.
In general, you must be 18 or older to buy a gun in Canada. Some exceptions are made for minors 12 to 17 owning a non-restricted firearm but only if a licensed adult is responsible for the gun.
