[^1]\n\nThousands of homes and businesses across the Greater Toronto Area and parts of Ontario's Golden Horseshoe remained without power after a severe storm flooded streets, knocked down trees, and damaged utility lines on September 2, 2026. [^2]\n\nAt least 45,000 customers were without electricity as of 8pm on Wednesday according to electricity provider Toronto Hydro. [^3]\n\nThe storm brought down trees and caused flooding, prompting road closures in the city, including on the Don Valley Parkway, according to the CBC. [^4]\n\nThe storm brought torrential rain, strong winds, and large hail, prompting tornado watches and warnings in some areas. [^5]\n\nHydro One, the province's Crown-owned power supplier, reported on early Thursday, September 3, 2026, that 53,000 customers were still offline. [^6]\n\nPrime Minister Mark Carney was set to travel to the northern Ontario city of Thunder Bay on September 3, 2026, to announce a historic investment in Canadian manufacturing. [^7]",
