The winter storm moving into Ontario this morning could create hazardous road conditions with a messy mix of heavy snow and rain.

This morning (Jan. 9), Environment Canada renewed a special weather statement and advisory for southern Ontario including Peel Region, Halton, Hamilton, Niagara Region and Durham Region.

The first big storm is on the way — expected to arrive mid-morning in much of Ontario.

There are already school bus cancellations, and Pearson Airport in Mississauga suggests travellers check their flights.

“With 120 specialized machines, an airside operations area equivalent to 3,000 NHL hockey rinks, and the capacity to deice 500 planes per day, our dedicated team of 270 is on the clock 24/7 to ensure your safe travels,” Pearson said in a post on X.

A mix of snow then rain is forecast for the most southern regions of the province. While other areas to the north and east could get up to 20 centimetres of snow, followed by a risk of freezing rain.

The storm system is expected to bring “heavy” snowfall at times with about five to 10 centimetres possible, although amounts may be significantly lower closer to Lake Ontario where snow may change to rain sooner, according to Environment Canada’s weather statement this morning.

“Difficult travel conditions will be likely once the snow arrives,” the statement reads.

The weather advisory forecasts the snow changing to rain in the afternoon or early evening with rainfall amounts of 20 to 30 millimetres. Ponding of water on roads is possible.

The rain is expected to continue into Wednesday.

“There may be a significant impact on rush hour traffic in urban areas,” the statement reads. “Take extra care when walking or driving in affected areas.”

Police across Ontario are warning residents of possible hazardous conditions on the roads.

Hamilton Police suggest drivers slow down for better control, increase following distance for safer stopping, brake gently to prevent skidding, and avoid sudden movements for smoother driving.
