I used an Outfitter in MN for bears as baits have to be established and gas and time for me to drive 8 hrs one way every weekend is not feasible. The baits wereon state land.Canada makes it a requirement, it pads the Canadians pockets. Bears are overun in Canada as like Germ said, no spring bear hunts in ON, which holds 75% of Canadas black bear population(last I knew on that figure) and locals don't hunt bears.Canadian localslook at you like you are stupid when you tell a local you hunt bears.
Now, leasing and outfitting are two seperate issues and sometimes they are tied together though with an outfitter leasing ground. I don't understand though how leasing would be mandatory or law as in your original question. How do you make leasing a law??
