Emergency Medical Services (EMS) of Alberta is offering some tips to reduce your risk of sustaining a cold weather emergency:

Dress with warm insulating layers closer to the body, covering with wind and waterproof layers on the outside.

Don’t forget a toque, and carry an emergency roadside kit in your vehicle containing extra clothing, blankets, and emergency supplies.

Make sure your cellular device is completely charged when you travel.

They've also outlined some of the potential results of cold exposure. 

The first is frost nip. Frost-nipped skin is extremely cold, but not yet frozen skin, and it will likely look red and be numb to the touch. As the least severe of the conditions, it usually heals fine by moving to a warm environment and gently re-warming with skin-to-skin contact. 

Frostbite occurs when skin becomes so cold, the skin and underlying tissues freeze. Frostbitten skin looks white, waxy and feels hard to the touch. Recovery includes moving to a warm environment, placing the affected area in warm water and possibly seeking further medical attention. 

"Hypothermia is abnormally low body temperature, less than 34°C. Early hypothermia may manifest as profound shivering; moderate hypothermic patients may act inappropriately: stumbling, mumbling, and fumbling, as their body temperature continues to drop resulting in severe hypothermia (<30°C)"

Hypothermia may result in unconsciousness or death if it is not treated properly and promptly. 

"Initiate gentle re-warming as quickly as possible. Remove any wet or constrictive clothing; cover with blankets, or sleeping bags. Protect from further heat loss: eliminate contact with cold surfaces, and shield from wind and moisture."
