Since Thanksgiving 2015 OPP have checked me out twice where I shoot on crown land. Both times my MR1 and loaded PCV .50 Beowulf mags are sitting on the table. They didn't even ask to look at anything. Just checked that things looked safe and that I wasn't poaching, I guess. Never asked to see a license either. Just suggested one or two more danger signs as in his experience ATV drivers are a bit dumb. (One road through a orange cone, danger sign, and saw horse just as he said dumb and proved his point.)
