From the CBC:
Tour outfitters, researchers and others could be allowed to carry firearms in northern national parks where polar bears are present, if proposed changes to federal parks regulations are adopted.
Parks Canada is consulting the public in communities near its northern parks, such as Auyuittuq National Park in Nunavut, about the idea of allowing firearms under specific circumstances.
If the regulation changes are approved, certain park visitors, such as researchers and outfitters, would be allowed to carry and use firearms in all parks where there are polar bears.
The proposed regulations would apply in all northern national parks where polar bears are present, say Parks Canada officials.
