Much of Canada has been plunged into a deep freeze for the first full week in 2015, and weather warnings are in place in many provinces.
B.C. Alberta, Manitoba, Ontario, Quebec, Newfoundland, and New Brunswick are all under weather warnings issued from Environment Canada.
On Sunday, temperatures in Winnipeg remained steady at -27, but wind chill made it feel a lot more like -40 overnight. That cold air is expected to move into Ontario.
Freezing rain also knocked out power to more than 150,000 people in the Montreal area on the weekend.
In the Maritimes, a mix of snow, sleet, and rain bogged down airports with delays.
The warnings are for extreme cold conditions and extreme wind chills. Residents in those areas are being reminded to wear appropriate clothing and dress in layers to protect themselves against the cold.
Warm socks, gloves, a hat, and a scarf are also essential in the cold weather.
As for Calgary, there is no warning in place, but wind chill will actually make it feel a lot more like -30. Snowfall is expected to pick up overnight, with about 10 cm accumulation.
Police say that in the last 24 hours, there have been 173 crashes reported within city limits.
Environment Canada typically issues extreme cold warnings when very cold temperatures or wind chill creates an elevated risk of frost bite or hypothermia.
