Crossing the border with muskets
There are no restrictions or special permits/license required to bring flintlock long-arms (please note that pistols are not permitted) into Canada as Canadian Gun Laws view antique and reproduction flintlock long-arms as reproduction antiques and NOT as firearms. You must declare your flintlock musket or rifle when you enter the country and answer all questions politely and directly. Your purpose on entering the country is to attend the historical reenactment.

This why the Chief Provincial Firearms Officers for Quebec will send a notice to Canada Customs regarding this event. we will also provide a welcome letter for your to show at Customers.
