"Air guns that meet the Criminal Code definition of a firearm, but that are deemed not to be firearms for certain purposes of the Firearms Act and Criminal Code are those that have a muzzle velocity of less than 152.4 meters per second (500 feet per second) and/or a maximum muzzle energy of 5.7 joules (4.2 foot pounds). Such air guns are exempt from licensing, registration, and other requirements under the Firearms Act, and from penalties set out in the Criminal Code for possessing a firearm without a valid licence or registration certificate. However, they are considered to be firearms under the Criminal Code if they are used to commit a crime. The simple possession, acquisition and use of these air guns for lawful purposes is regulated by provincial and municipal laws and by-laws. For example, some provinces may have set a minimum age for acquiring such an air gun. These air guns are exempt from the specific safe storage, transportation and handling requirements set out in the regulations supporting the Firearms Act. However, the Criminal Code requires that reasonable precautions be taken to use, carry, handle, store, transport, and ship them in a safe and secure manner.[5]
Carrying one of these firearms is permitted for those aged 14 or older."
