Here's my experience with Canadian Customs..
First week after graduation...a buddy and me decide to take a 3 week camping vacation to Nova Scotia and back in my 66 Chevelle. W.MI to Detroit and then the tunnel to Canada...on the the other side of the turnnel in Windsor, the first Canadian customs agent didn't like the looks of us with hair down to the middle of our backs and orders us out of the Chevelle.
First thing he does is push all our gear to the side in the back seat so they he can squeeze his fat azz in there and pushes his hand down in between the back seat and the seat cushion and sweeps it across and pulls out a couple pot seeds.
He orders us into the cement block building beside the car and a couple other cops order us to strip....then spread. They didn't find anything in or on us, the car or our clothes.
I remember looking out the small high window in the building and seeing my car with all it's contents spread out on the tarmac in rows. When we were released, all was back in order in the car. Couldn't even tell that anything had been done.
The whole ordeal took less than an hour and we were on our way to NS again.
