I disagree with the last part of this.The Garand is exempted since it is difficult to reduce its charger integral capacity to 5 rounds. God knows why the specific mention in legislation of the Lee Enfield, since it is not a semi-auto, but the 5 round magazine capacity applies only to semi-auto centrefires (rifle or shotgun). You can buy a 10 round magazine for a Remington pump action centrefire rifle and that is legal. If you put that same magazine (which will fit) in a Remington autoloader, it becomes a prohibited device. There may be more restrictions in game laws (eg: migratory bird act) but in ON at least, there is no other restriction on magazine capacity. Certain specific magazines (eg SKS, 30 Rd., are designated as high capacity and are illegal even if they are used in a bolt gun unless reduced to 5 rounds. If this seems confusing, that is because it IS.
