With freezing rain, heavy snowfall and extreme cold conditions expected from coast to coast, the winter season is flexing its muscles with a gamut of miserable weather conditions.

Quebec

In Quebec, approximately 74,000 people were without power as of Sunday night -- down from a peak of 150,000 -- as the province deals with icy conditions, according to Hydro Quebec.

Parts of the province saw 15 to 20 cm of snow fall overnight, but the real concern has been the buildup of ice.

Environment Canada had issued freezing rain warnings for both Montreal and Quebec City on Sunday afternoon.

The winter storm was expected to bring an extended period of freezing rain to Southern Quebec that could leave a buildup of 5 to 15 mm of ice.

Ontario

People in Southern Ontario might want to pull on their parkas. Environment Canada says a blast of arctic air will bring the coldest temperatures of the winter to date.

The frigid air mass arrived Sunday night, and residents can expect a "deep freeze" for the rest of the week.

Temperatures will drop well below average for early January, and lows of -20 C or below can be expected on the coldest days. However, areas close to the shorelines of the Great Lakes may bottom out somewhere between -15-C to -20 C.

Ontarians are still dealing with a messy mix of snow and rain that hit the region over the weekend. The Ontario Provincial Police have advised drivers to take caution as roads may be slippery.

The Ottawa region was under a freezing rain warning Sunday, with "significant" ice buildup in the forecast.

Parts of northern Ontario are under extreme cold warnings as temperatures in places such as Thunder Bay could dip to below -40 C with the wind chill Sunday night and on Monday.

Maritimes

Fluctuating temperatures in Atlantic Canada will produce messy conditions.

A warm front stretching across southwestern Nova Scotia will head northward on Sunday night. As temperatures rise, ice pellets and freezing rain will transition into rain. Halifax could see temperatures as high as 12 C on Monday. The storm could dump an estimated 20 to 30 mm of rainfall over the central and southern areas of the province.

The Prairies

Most of Manitoba, Saskatchewan and Alberta remain under an extreme cold warning. A frigid arctic air mass is expected to drop temperatures into the minus-30 range, with the wind chill pushing them into the low minus 40s in Winnipeg, Saskatoon and Regina.

Environment Canada warns that extreme cold warnings create an elevated risk of frost bite and hypothermia.

British Columbia

A major winter storm is moving across the coastal areas of the province. Wet snow was falling in parts of Vancouver and the Fraser Valley Sunday. Coastal areas can expect just a few centimetres of snow, but inland areas should see closer to 20 cm.

Environment Canada says to prepare for "quickly changing and deteriorating travel conditions."

Warm Pacific air will turn snow into heavy rain, and freezing rain is expected over parts of the Fraser Valley on Sunday night.

Metro Vancouver could see more than 50 mm of rainfall dumped over the area beginning Sunday and extending through Monday.
