Firearms Allowed, Restricted and Prohibited
Approval of the Non-Resident Firearms Declaration allows only standard rifles and shotguns commonly used for hunting and target shooting to be transported into or through Canada.
Handguns with at least 4-inch barrels are considered "restricted" firearms and are allowed in Canada, but require the completion an approval of an Application for an Authorization to Transport Restricted Firearms. This Non-Resident Firearm Declaration costs $50 Canadian.
Handguns with barrels shorter than 4-inches, fully automatic, converted automatics, and assault-type weapons are "prohibited" and not allowed in Canada. In addition, certain knives, even those used for hunting and fishing, may be considered prohibited weapons by Canadian officials.
