Yes ,the peeps that steal have all the rights,after having 2 snowmobiles stolen i set up a connibear 330 beside my sled but removed it after been told I would be in big trouble.still would have been nice to maim a thief.The land of permits, fees and taxes, I think all provinces are the same.
What ever you decide on how to deal with trespassers be careful, ending up in court is better than ending up with a bullet in your head. Sad, so many crazy people out there.
