I've often wondered about this as I heard from a few different people that if you get a prospectors license you can carry in the wilderness.
From Cariboo Gold Miners Association Thread one guy posted the following:
you have to pass a proficiency test with the firearm you'll be carrying. second you have to write a letter stating why you have to use a sidearm instead of a long gun ''example'' backpacking deep into remote areas for prospecting,and where there weight of a long gun becomes an issue due to long range bush travel on foot, third send all copys above with your ''application for an authorization to carry restricted firearms and prohibited handguns'' You can get a 1 year, or a 2 year permit. when your permit expires you have to do the above all over again. you cant just go online an stake a claim in the middle of nowhere and say your going there, you have to prove what you say. The smallest gun you can use is a 44 mag.
From Firearmstraining.ca:
Certain individuals who need restricted firearms for protection against predators in the wilderness (eg. trappers, prospectors), or for survival (eg. bush pilots), can obtain such a permit through the CFC, after completing a special wilderness training course.
While self-defence is a legal purpose, it is virtually impossible for an average citizen to get a permit to carry a concealed firearm for self-protection.
As per the OP, confirmation of the above would be interesting if any cgn'er has personal experience with this?
