As far as I know the guns were purchased before the new Canadian laws came into effect. When that happpend, customs no longer liked our Airsoft guns coming into Canada. There is a form on here that breaks it down for you, so you can understand what the rules are about importing and know the history of importation. Basically, the guns that you see in the classifieds were purchased before the laws, and people are selling them for what ever reasons. All my guns that I have bought have been previously used. That's my two cents.
