I did this once just to try it, I live near the border. I was driving home for the spring(seeding time) I packed my gear up and put my guns in their proper cases. I had a real sword svd, and type 56. Also a g&g m4. I did not try to bring a shotgun or pistol. I talked to the cbsa, got my y38(green slip it was nicknamed cause its green) and they looked at them, made sure they weren't real. I left, drove home from Alberta to sask (threw montana)and upon entry I told them my car was full of suitcases full of my clothes and that I had my guns, gave him the form and had no trouble coming back.
