Ontario snow storm

There are snowfall, freezing rain warnings, and weather advisories in effect for Mississauga, Brampton, Hamilton, Halton, and Durham Region as a winter storm is expected to hit much of southern Ontario today (Dec. 15).

The snow is expected to make for a messy afternoon commute across the GTA and beyond, as Environment Canada has issued warnings and advisories for many cities and regions.

School boards in York, Peel and Halton have cancelled school buses, while GO Transit and Pearson International Airport both told passengers to check ahead for possible weather-related disruptions.

Here are the latest Ontario snow storm updates:

Mississauga and Brampton

A winter weather travel advisory in effect for Mississauga and Brampton. Environment Canada says to expect snowfall of up to 10 cm and up to 15 cm, with peak snowfall rates of 1 to 3 cm per hour.

There is a risk of freezing rain, and blowing snow is expected to reduce visibility with southeasterly wind gusting nearly 70 km/h.

“Motorists should expect hazardous winter driving conditions and adjust travel plans accordingly,” Environment Canada said. “If visibility is reduced while driving, turn on your lights and maintain a safe following distance. Surfaces such as highways, roads, walkways and parking lots may become icy and slippery. There may be a significant impact on rush hour traffic in urban areas.”

Brief freezing rain is possible in the morning, transitioning to snow near noon. Environment Canada says the snow will taper to flurries or drizzle early in the evening.

Hamilton

Environment Canada is forecasting between 15 to 20 cm of snow, with the greatest amounts expected over the higher terrain north of Lake Ontario. Snow will develop late in the morning and reach the Peterborough to Cobourg areas by early in the afternoon, tapering into flurries by Friday morning.

Drivers are being warned to be prepared to adjust your driving with changing road conditions.

The storm is expected to move eastward dumping up to 20 centimetres of snow on areas along Lake Ontario’s north shore before landing in Ottawa tonight, where Environment Canada is forecasting up to 25 centimetres of accumulated snow by Saturday morning.
