Normally the people who live there take a .22 rifle as a survival gun.The main reason is because the shells are so light. You can carry an awful lot of .22 caliber shells in a pocket.
Pistols are not allowed for hunting in Canada and even if they were allowed they are so much less effective than a rifle that no one would take them into the woods with them. They are just dead weight.
Shotguns are usually not counted as a survival gun because of the weight of the shells too.
Survival strategy usually focuses on smaller animals and involves techniques which we would consider poaching.
I was using the term survival in the sense of protecting one self from grizzly, polar bear, charging moose, etc. Not in the sense of using it to survive as a source to bring food to the table.
RE: Pistols... they are fine hunting weapons in skilled hands, and are used for such in the USA. Again, I was referring to pistol as survival as protecting one self and not putting food on the table.
Also, I am not aware of where he went as I didn't read into his story nor do I get TV service. So I am not sure if he needs protection from such animals, but going into the woods alone I would chose a pistol if I was hiking

And others depending if I had a base camp etc.
Can you own a handgun in Canada?
The website is confusing because it says certain calibers are prohibited, and then the ones not listed to be prohibited are restricted. Does restricted mean you can't own it at all?? It's written clear you can't own one with a barrel under 4.14" or .32 or .25... the rest are just "restricted".
