I have attached the web page explaining the firearm laws in Canada. Please read this very carefully as you could encounter problems at the Canadian border/customs if you do not have the proper paperwork for your firearm. It is a very simple procedure with a nominal fee of $25.00; however, if it is not completed properly you will not be able to bring your firearm into Canada.
Ensure you read the section on Firearms Import Procedures for Individuals
You must have the form completed and present it to a customs officer for his/her signature after inspection of your non-restricted firearm.
The Non-Resident Firearms Declaration (Form CAFC 909) must be presented in triplicate, unsigned, to a customs officer at your first point of entry into Canada.
For more information on declarations by visitors, please call the Canada Firearms Centre (CFC) at 1-800-731-4000, or visit their Web site at www.cfc-cafc.gc.ca.
