NOTE: There are NO handguns or fully automatic weapons allowed into Canada. Your firearms and other items of value should be registered with U.S. Customs on your way into Canada to ensure a smooth crossing on your way back home. More information on Firearm Declarations may be obtained by calling 1-800-731-4000 or by downloading the Firearm Declaration Form (CAFC 909) – in PDF printable format. Border crossing regulations require U.S. citizens to prove identity and citizenship so possession of a driver’s license and passport is mandatory.
