Q7. What is the maximum number of cartridges that a firearm magazine can legally hold?
A7. As set out in Criminal Code Regulations, some large-capacity magazines are prohibited regardless of the class of firearm to which the magazines are attached. As a general rule, the maximum magazine capacity is:
• 5 cartridges for most magazines designed for a semi-automatic centre-fire long gun; or
• 10 cartridges for most handgun magazines
A large-capacity magazine is not prohibited if it has been permanently altered so that it cannot hold more than the number of cartridges allowed by law. Acceptable ways to alter a magazine are set out in the regulations.
There is no limit to the magazine capacity for semi-automatic rim-fire long guns, or for other long guns that are not semi-automatics.
