Here's info about that from the Royal Canadian Mounted Police:
"In general, the only firearms allowed for wilderness protection are non-restricted rifles and shotguns. The following individuals, provided they are Canadian residents and have a licence that allows them to possess restricted firearms, may be authorized to carry a handgun or restricted long gun for wilderness protection:
-licensed professional trappers, and
-individuals who need protection from wild animals while working at their lawful occupation, most often in a remote wilderness location."

Nobody likes armed foreigners frolicking through their forests.
Canadians are no different in that regard.
You want something for wildlife protection, buy yourself a bear banger.
Bear Bangers are pen launchers that fire a variety of cartridges:
-Ones that explode with a sound equivalent to a shotgun blast; screamers that make a whistling noise that scares the bejeezus out of wildlife; and flares in case you get into trouble.
Google 'bear bangers" and you'll find all sorts of info online, such as these examples:

I'm Canadian. I've been coast to coast to coast through all ten Provinces and 3 Territories.
I've never needed a gun for wilderness protection.
And only used a bear banger once: To scare away a skunk, not to defend myself from bears, wolves, bobcat and cougars.
Trust me when I say a bear banger's all you actually need.
And personally, I don't trust foreigners with even those. Damn fool idiots playing with flares could accidentally start a forest fire or something.
