Damn. Nice necro.

But you can legally buy 9mm PAK blank firing guns in Canada. Models by Zoraki are completely legal, as they aren't replicas of any existing real gun. They even fire full auto, and there's no legal issues except regular laws about using them in public, firing in city limits, etc.

Any replica of an actual firearm is considered a replica and is outright illegal to import or transfer without the proper licensing in place.
