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.

A trapper teaches a novice how to survive frigid temperatures.

Becky braves sub-zero temperatures to fish a remote, frozen lake, and Bentley heads cross-county.

Becky makes a last-ditch effort to harvest a Muskox, and Kim and Pierre must upgrade their shelter.

Mike comes up with a novel way to procure an ample stock of firewood.

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

Desperate to harvest a musk ox, Becky, Dene and Thi head out in to the unforgiving barren lands of the Northwest Territories; Kim and Pierre try to outfox a wolf that threatens their new trap line; Bentley begins preparing a wolf hide for market.

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.

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.

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.
