Much like criminals who use guns to commit crimes, poachers who illegally take game don't worry too much about the rules governing when and where you can take a firearm into the bush, or what firearms you might use. Newfoundland's poaching issues have little to do with our antiquated laws prohibiting shooting on Crown land without a valid permit and a lot more to do with traditional (if poorly reasoned) practises and lack of enforcement.
Begging to differ, but if the restrictions were off, anyone at all could take a firearm into the woods, both citizens and poachers; making it difficult for Wildlife officers to tell who is just target shooting and who is poaching; unless the poacher is actually standing over a dead moose.
As it stands now, if your in the woods with a firearm, your either a shooter with a permit or a poacher. No trouble to tell who's who now.
The permits are free, and available at any Wildlife/Forestry office. No reason why someone shouldn't have one.
It's a small price to pay to ensure the health and safety of our wildlife resources.
