I’ve had no problem. The only issue I had was when I had shot shells in my truck. When they strip searched my truck, I literally had ammo I had no idea I had in there. Ooops
I had a few spent .22 hulls in the open bed of my truck left over from a shooting session a few days before....
My truck was DISASSMEBLED...the interior was removed, the dash, the doors, anyplace they thought i might be able to stash a .22. Left everything sitting in the rain for 4 hours while I was grilled, then the Mounties took their tools and went back inside, leaving me to reassemble my truck interior with a Swiss army knife, a crescent wrench and a pair of needle-nosed pliers.
I was pretty pissed, but i now make SURE that there is NOTHING objectionable in my truck before i go into Canada.
