A massive winter storm is set to blanket Southern Ontario with a whopping 20-30+ cm of snow, turning the region into a winter wonderland, or a potential travel nightmare. But here's the catch: this storm is no ordinary snowfall.
Published on January 24, 2026, at 3:32 PM, this weather alert warns residents of Southern Ontario, particularly the Greater Toronto Area (GTA), to brace for a significant winter storm. The storm, originating from the U.S., is expected to bring heavy snowfall, with potential accumulations of 20-30+ cm, impacting travel and daily life.
Updated at 5:25 PM, the forecast highlights the storm's potential impact on Eastern Canada, with copious snowfall and travel disruptions. Southern Ontario, especially the GTA, the Golden Horseshoe, and the Niagara region, are in the storm's direct path.
Yellow-coded storm watches and warnings are in effect, urging residents to prepare for rapidly changing travel conditions. The storm's impact will be felt across various highways (QEW, 401, 404, 407) and airports, causing potential delays.
The storm's secret weapon? Ample moisture from the north colliding with frigid air over Eastern Canada, creating the perfect recipe for heavy snowfall. Ontario, on the cold northern side of the storm, will experience all precipitation as snow.
And here's where it gets interesting: Temperatures in the -10s to -20s will result in fluffy, rapidly accumulating snow, challenging even for snowplows. The GTA and Golden Horseshoe can expect widespread snowfall, with potential accumulations exceeding 30 cm in some areas.
Snowfall timing: Starting Sunday morning, peaking in the afternoon and evening, and continuing into Monday morning. Wind gusts near 60 km/h will create blowing snow, especially near Lake Ontario, further complicating travel.
Snowfall distribution: The heaviest totals are expected under the snow band, stretching from Hamilton to Pickering, including Oakville and Toronto. Communities north of the 407, like London and Barrie, can expect 10-20 cm of snow. Eastern Ontario, including Ottawa, will see 10-25 cm, with travel disruptions lasting into Monday.
Post-storm conditions: Any snow that falls will stick around due to below-freezing temperatures. The following week will be frigid, with temperatures in the minus teens and lows in the -20s. Colder-than-normal conditions may persist until mid-February.
