It's deep in to the winter season and this time of year the only thing deeper than the sub-zero temperatures is the unrelenting snow that presents unique challenges for those living off grid in the Canadian wilderness.

When you live in the remote Canadian wilderness, public enemy number one is the cold, and when weeks of sub-zero temperatures take hold the simplest of tasks are transformed into life-threatening chores.

Winter has arrived in the north, and as temperatures sink well below zero, new challenges and perils emerge for those who live in the vast Canadian wilderness.

With winter staring everyone down the barrel, it's an all-in, final push to prepare for the brutal season ahead.

As the days grow shorter and the temperatures begin to drop, everyone ramps up their preparations for the fast-approaching Canadian winter.

Everyone in the north has their own priorities when prepping for the fast-approaching winter, but filling their stomachs, is at the very top of most of their lists.

In the deep bush of northern Canada, winter preparation can mean the difference between a tough season and a deadly one, so even before summer is out, winter is on everyone's minds.
