More than 2,000 homes and businesses in the Rosedale area lost power Wednesday night.
The outage spans from St. Clair Avenue to Rosedale Valley Road and between Mt. Pleasant Road and Bayview Avenue.
As a result of the power outage, traffic lights are reportedly out at Bloor Street and Castle Frank Road. Drivers are being asked to treat the intersection as an all-way stop.
The issue will take several hours to fix and Toronto Hydro estimates power will likely not be restored until 8 a.m. Thursday.
