Provincial highway crews across Nova Scotia are urging drivers to stay home unless it's an emergency as a snowstorm moves across the province.
There have been several collisions reported and a few cars were spotted off the road during the morning commute on Wednesday.
Cape Breton RCMP received a call about a two-vehicle collision on the Canso Causeway at around 10:30 a.m.
Four people were sent to hospital with minor injuries and the highway was closed for two hours, reported the CBC's Holly Connors.
By late morning, heavy and wet snow made driving difficult on many eastern Cape Breton roads.
RCMP Cpl. Ron MacDonald, with the highway patrol unit in North Sydney, said there were at least three minor accidents.
"People have slid off into the ditch. Very little if any damage to their vehicles, but more or less showing that the roads are getting quite slippery and slick," said MacDonald.
"They are snow covered all over."
The Cape Breton Regional Police also reported heavy traffic and a few fender benders near the Mayflower Mall.
In Halifax, a 33-year-old woman was taken to hospital after she was struck by a car driven by a 39-year-old man at around 7:30 a.m. while she was crossing Lacewood Drive in Clayton Park.
Police said she's expected to recover.
No charges have been laid.
Another woman was taken by ambulance to hospital after the car she was driving slid off Highway 103 on Wednesday morning.
