I've hunted them in 2 places in the province. Different counties have different bounties on them. Contact a few county offices to determine what sort of bounty they offer. I think the most I have heard of is $50 per scull. However I have never turned one in. Only kept it for meat. Very hard to hunt as well as they move around a lot and usually like the dense willows and muskeg (In my experience).
Also contact your local UFA and see if any farmers in your area have complained about them. Most UFA's keep lists of farmers who want problem animals eradicated (Gophers, wild russian boars,..etc..).
Good luck!
