A storm system that dumped 15 to 25 centimetres of snow on southern Ontario and Quebec is continuing its eastward march toward the Maritimes.
The blanket of fresh snow, along with chilly temperatures, created traffic troubles both on the ground and in the air in Central Canada.
Dozens of flights through Toronto's Pearson and Montreal's Trudeau airports were delayed or cancelled yesterday.
Ontario Provincial Police said the weather may have also been a factor in a head-on collision that killed two people near Barrie, north of Toronto.
There were many accidents on snowy roads around the region, including a 20-car pileup on the Queen Elizabeth Highway in Mississauga just west of Toronto.
The storm system was expected to pick up steam as it moves into the Maritimes today.
Winter storm warnings are in effect with snowfall amounts of between 30 and 40 centimetres forecast for southern New Brunswick, and slightly lesser amounts for parts of Nova Scotia and Prince Edward Island.
