Toronto began cleanup operations Thursday after a severe thunderstorm brought torrential rain, large hail and damaging winds across the city and parts of southern Ontario.

The storm caused flooding, fallen trees, damaged power lines and widespread electricity outages. Toronto officials said the event produced rainfall levels that met the city's definition of a “100-year storm.” Global News reported that some parts of Toronto received about 150 millimetres of rain within a few hours.

Flooding And Power Outages Hit Toronto

The Don River overflowed during the storm. Flooding forced closures on parts of the Don Valley Parkway and other major roads. The DVP reopened Thursday morning after water levels fell and crews cleared affected areas.

Toronto Hydro said about 45,000 customers lost power during the storm. The utility said roughly 90% of its customers had been restored by Thursday, while crews continued dealing with damaged trees and power infrastructure.

Toronto officials received about 1,000 storm-related service requests. Toronto Fire Services also handled nearly 1,500 calls during a 24-hour period. Officials said this was the service's second-highest daily call volume, behind the 2013 ice storm.

Rogers Stadium Sustains Major Damage

The storm also damaged Rogers Stadium at Downsview Park. Live Nation Canada said the 50,000-capacity outdoor venue suffered “significant damage.” No injuries were reported.

Images from the site showed damaged grandstands, displaced seats and debris. Live Nation said it was assessing the full extent of the damage.

The venue is scheduled to host AC/DC on Sept. 16. Live Nation's current event listing still shows the concert, but the company has not confirmed whether the storm damage will affect the event.
