Tresspassing for the purpose of hunting, in Ontario is $150.00 fine
This problem happened to me during deer rifle season Nov-2012. Two truck loads of men crossed my land, (without permission) to gain access to crown land behind my property. There is an access trail through my land to get to the crown. I did post it all summer and fall that the road would be closed for deer season. I did allow access to the crown land prior to this incident during the non hunting season. To make a long story short, I confronted the men on their way out on my property. There was a lot of discussion. Point blank I told them if you come back your tresspassing. They basically told me they thought the trail was a road allowance and would cross may land when they want.
I had no choice but to call the MNR. And in return the MNR talked to the hunters. The MNR at thier liberty could of given each hunter a min of $150.00 fine for tresspassing for the purpose of hunting. And as well taken thier game. Heavier and more damaging charges could of a also be laid but this was bare minumum .
Anyway they got a warning because the trail was not clearly marked the rain had damaged the signs. So it is clearly posted now, and next time there will be more than just a warning.
So the moral of the story is if you don't want people shooting up your land and tresspassing, POST POST POST IT ! ! !, I can't make myself any clearer
