Public Safety Canada has stated: It will “Close the gap in the Criminal Code regarding ‘replica’ firearms by ensuring the prohibition on importation, exportation and sale applies to all non-regulated airguns that look like modern firearms. Un-regulated airguns that look like modern firearms and fire a projectile below 366 feet per second (fps) are already considered replicas, and are prohibited. This amendment will close a gap to ensure that air guns firing a projectile between 366 and 500 fps are also considered replicas if they look like modern firearms. Current owners will be allowed to keep those they already own, but they cannot transfer them to another person.”
