Hopefully it’s just a taxidermist or butcher shop not properly disposing their by products. But if that were the case it does seem like there would be more bones than just the paws. Hopefully their local claw guy is as well known as our local jerky guy and they have somewhere to start questioning To find out if it was poaching or not. Not sure what kind of hunting rights the Native Americans in Canada have but they could possibly do it and be fine as long as they said it was ceremonial. Lots of different possibilities.
