Southern Ontario snow squalls continue, with heavy totals and bitter cold

Southern Ontario will begin the new year with even more snow as a multi-day lake-effect event keeps on to bury communities across the region.

Snow depths on Friday morning varied from 15 cm near Ottawa and King City to nearly 60 cm northwest of Barrie and Sault Ste. Marie. Some areas south of Barrie have seen over 50cm of snow, with more to come.

Toronto has already received over 40 cm of snow in December, making it the snowiest December in nine years.

Snow bands still on the move

The lake-effect snow is expected to affect southern Ontario through the weekend. Below-freezing daytime highs and persistent wind chills will cause snow showers and heavy snowfall.

Snowfall amounts will vary greatly depending on where the bands settle. Some areas may receive only a few centimetres, while snow belts and areas north of Barrie could receive an additional 20-50 cm.

Forecasters are keeping an eye on a particularly intense squall that is expected to pass over Collingwood, Barrie, Midland and Orillia. Snowfall of up to 50 cm can reduce visibility and pose a risk to travel. Highways 400 and 11 may remain closed in affected areas.

Snow is expected to be light and fluffy in the cold air, but blowing snow will continue to cause hazardous driving conditions.

Bitter cold and dangerous wind chill

Ontario is entering 2026 with wind chills in the -20s across the south and -30 in the northeast.

Temperatures are expected to drop to -25°C in Ottawa and -30°C in Timmins overnight on Friday. Forecasters warn that exposed skin can freeze in minutes in these conditions, so residents should dress in layers and limit their time outside.

Southern Ontario is facing a difficult start to the year as snow continues to fall and temperatures remain cold. Residents are advised to stay informed about conditions and exercise caution when travelling.
