Southern Ontario Storm Leaves Thousands Without Power

A powerful storm swept through southern Ontario on Wednesday, September 2, 2026, leaving tens of thousands without power, causing widespread flooding, and disrupting transportation. The severe weather brought torrential rain, large hail, and raised concerns about possible tornado activity across the Greater Toronto Area and beyond. As of Thursday morning, September 3, cleanup efforts were underway while thousands remained in the dark. Toronto Hydro reported approximately 8,300 homes and businesses were still without electricity, while the province's Crown-owned power supplier, Hydro One, indicated more than 47,000 customers remained offline across Ontario. The storm inundated major roadways, forcing closures on parts of Yonge Street and the Don Valley Parkway. Subway services experienced disruptions during Wednesday's evening rush hour due to flooding and debris. Toronto officials stated the city received roughly 1,000 service requests following the storm, with city crews working to clear debris and sediment from roadways.
