Southern Ontario and Quebec got their first blast of winter on Saturday and now it’s the Maritimes’ turn.

On Sunday morning, Environment Canada said an intensifying low pressure system would pass over Nova Scotia bringing significant snowfall and strong easterly winds.

“Snowfall amounts of 30 to 40 cm are expected across southern New Brunswick while over northern New Brunswick snowfall amounts of 10 to 20 cm are forecast. The snow will be accompanied by strong easterly winds gusting up to 70 km per hour,” the agency said.

A winter storm warning was also issued for Prince Edward Island and Newfoundland, with total snowfall accumulations of 15 to 30 cm expected by Monday evening.

Toronto and areas around the west end of Lake Ontario, including Hamilton and Burlington, got dumped with nearly 20 cm of snow Saturday.

Two people died in a collision near Barrie, Ont., Saturday afternoon and police said blowing snow was possibly a factor in the crash. And a 20-vehicle crash closed the QEW in Mississauga.

“11 collisions in the last hour in Mississauga and Brampton. Please slow down and give yourself plenty of room to manouver,” the OPP tweeted Saturday afternoon.

Quebecers continued to deal with poor visibility, blowing show, and frigid and slippery roads Sunday morning. At least three people were seriously injured in a multi-car car pile-up on a Quebec City highway. In total, seven people were transported to hospital after at least 10 vehicles crashed into one another. However, police said none of the injuries were life-threatening.

A section of Hwy 40 in Montreal’s east end was closed Sunday morning after a crash involving around 10 vehicles. Transport Quebec’s Twitter feed offered a steady stream of accidents, urging motorists to “Slow down, slow down, slow down."

Several afternoon flights out of Montreal's Trudeau airport were cancelled or delayed but Via Rail said trains were not impacted by the storm. In a statements, it said trains on the Québec City - Windsor corridor and in the Maritimes were running on schedule.

Up to 30 cm of snow are expected to fall in the Greater Montreal Area by Sunday night and the temperature, with the wind chill, will likely remain around -20 C.
