Lew you need to spend a day in my boat. I'm a magnet and target for them (out of province boat numbers).
A few years back while on Rice Lake I was checked three days in a row, twice in the same spot by same two OPP's & CO.
Another year on the West Arm they came straight to my boat while passing right by two of my Canadian friends.
Also had them check a couple of boats from our group and our cabin (while we weren't there) on a flyin north of Armstrong one year, I wasn't one of them that got check but I did hear and see the plane.
I've also been stopped twice on the road, one of them was a road block set up coming from the Red Lake Area, CO didn't believe me when I stated I had no fish and proceed to check everything in my truck, he was nice enough but I could tell he may have been disappointed.
