Alberta Clipper arrives in GTA
An Alberta clipper system brought snowfall and hazardous travel conditions to the Greater Toronto Area (GTA) on Wednesday, January 21, 2026. While conditions have improved in some areas, ongoing cold temperatures and the potential for further snowfall remain concerns for the region.
Current Conditions and Travel Impacts
The snowfall warning for the City of Toronto has been lifted. However, a snowfall advisory remains in effect for municipalities within the southern Durham Region. Environment Canada initially warned that up to 10 cm of snow could fall on Wednesday, with the snow expected to end in the late afternoon or early evening.
The Toronto Transit Commission (TTC) reported service disruptions, with buses bypassing certain stops due to weather conditions. Specifically, the 29 Dufferin bus route was not stopping near Dufferin Street at Davenport Road North Side. Salters were deployed in Mississauga to address ongoing flurries.
Regional Variations in Snowfall
According to Environment Canada warning preparedness meteorologist Geoff Coulson, snowfall amounts varied across the GTA. Eastern parts of the region, including Scarborough, Pickering, Oshawa, and Whitby, were expected to receive closer to 10 centimetres of snow. Downtown and western areas of the GTA were likely to see around five centimetres.
Coulson explained that lake effect snow continues to contribute to the system, with heavier amounts possible overnight and into Thursday in areas near Lake Huron and Georgian Bay. Flurries are also possible in Toronto on Thursday.
Looking Ahead: Continued Cold and Potential for More Snow
The current weather event is occurring during an extended cold snap. Temperatures are expected to dip to a low of -22 C on Friday and reach a daytime high of only -15 C on Saturday. Environment Canada anticipates “the coldest air of the season” this weekend, along with very cold wind chills.
Another potential system is being monitored for Sunday, which could bring significant additional snowfall to the GTA. While the exact amount of snow remains unclear, models suggest a potential accumulation of 10 to 20 centimetres, or even more due to the cold temperatures and less dense snow.
Safety Concerns and Public Alerts
OPP Sergeant Kerry Schmidt warned of blowing snow reducing visibility for drivers, particularly north of Toronto. Toronto police issued a warning regarding the unstable ice conditions on Lake Ontario and within the Toronto Harbour. No school bus cancellations were reported in advance of Wednesday’s weather.
