idk about the rest of canada, but you can't hunt with -06 in southern ontario. Buckshot or slugs only. You have to go way north (1000 km..?) to break out the hunting rifles. 7.62x51 is more popular than .30-06, which shouldn't be surprising, since the -06 was its immediate predecessor. We also can't hunt "big game" with .22LR, or any other rimfire.
Layering your gear is important, but so is weight. Usually people are in a group, and layering (via group pool) is more important in this case, because if something fails, the group can still function. Having backup emergency gear is lighter than carrying two axes, for example. Having a multiuse tool that acts as a shovel, pickaxe, hammer, axe, etc is ok as emergency backup.. But primarily I'd use my K-Bar and portable saw. You take a 2-3 foot "green/live" branch to use as a baton with the saw, then you fall a dead tree.. cut it up with the saw. Then using your knife, place it on top of a log u just cut and hammer it through with the baton.. hammer until knife is buried, then hammer the swedge, then the hilt, and back and forth until the log splits. Much less energy is expended than swinging (and carrying) an axe.
