We are restricted in many ways on the capacity of our magazines - most of them making no real sense.
Pistol magazines are limited to 10 rounds.
Rifle magazines are limited to 5 rounds, unless they are .22 cal and then they are unlimited capacity. If it is a bolt action rifle, then the capacity is also unlimited.
Shotguns are limited to 5 rounds if they are semi's, but unlimited for pump action.
These restrictions are Canada wide, so no different in Quebec or any other province.
Clear as mud, right?
The capacities are based on what the magazine is DESIGNED for, not necessarily used. This means that if a magazine designed for a pistol will fit in a rifle (such as the LAR-15 pistol mags, or XCR pistol mags), then even though they hold 10 rounds they are legal. If it is designed for a rifle, but can fit in a pistol then it is still limited to 5 rounds (such as mags for the Beretta CX storm).
We can still use full capacity magazines, they just need to be pinned or modified so as to not accept more than the legal limit or rounds for their designed platform.
The may be some other restrictions for hunting purposes (I'm pretty sure you can't have more than 3 rounds in your shotgun or 5 in your rifle at a time while actually hunting), but I'm not entirely certain of the specifics on these rules as I don't hunt anything other that paper, clays and steel plates
The short answer is we feel your pain, and welcome to the forum.
