i'm unformiliar with the candaian terrain and i don't even know what part of what kind of terrain you will be using this kit on. But a few suggestions.

I haven't seen a knife or (snow)saw. 2 very valuable tools to make shelter and fire to keep you warm. Properbly one of the most importent thing in cold conditions.

some tinder for you ferrosium rod, you only carry those tinder sticks. I'm not formiliar with them, but most tinder sticks are harder to light than normal spark grade tinder.

maybe matches, because it's harder and more importent to beable to make fire in cold temperature.

a thing to melt snow in, dehydration alone is dangarous and dehydration will creat a higher chance to get cold injuries. Think of a alluminium tray to melt snow in. But having a container to collect water with either a snow " marchmellow" or from a cloth sack filled with snow suspended close to a fire will be nice too.

first aid selection is a bit small, do you carry a additional FAK?
