Heavy rain causes widespread flooding, power outages in Toronto

A slow-moving storm system over Toronto caused flooding and power outages in several areas of the city, forcing emergency crews to rescue people stuck in elevators.

“We had these storms brewing over the northern parts of the GTA delivering heavy rain,” Global News meteorologist Ross Hull explained early Wednesday morning.

“There was certainly a high potential for heavy rain if these storms did move south and they did.”

Hull said winds blowing off the lake fueled the storm as it hovered over North York before moving toward the south end of the city.


According to a preliminary weather summary issued by Environment Canada on Wednesday after 12:30 a.m., the heaviest rain hit Highways 400 and 401, the area near Allen Road, the downtown core and the Toronto Islands.

The weather agency said approximately 50 to 75 millimetres of rain fell in the span of two to three hours across the area. Localized areas may have experienced higher amounts of rainfall.

“Note that most other areas across Toronto received much less than 20 millimetres of rain, thus showing the very localized nature of the heavy showers,” the statement said.

Hull noted the normal rainfall amount for the entire month of August in Toronto is 78.1 millimetres.

“[This storm is] basically more than a month’s rain … so you can understand how that could lead to significant flooding,” he said.

At 10:15 p.m. on Tuesday, Toronto Hydro said approximately 16,000 customers lost power due to a loss of supply from Hydro One.

But most of the outages were cleared by 12:30 a.m. on Wednesday.

That loss of power, combined with the volume of water, meant emergency crews had to rescue people trapped in elevators.

At a commercial building near Rockcliffe Boulevard and Alliance Avenue, southeast of Jane Street and Eglinton Avenue West, Toronto police said two people called 911 after 10:50 p.m. on Tuesday to report that they were trapped in an elevator in the basement as water began to fill it.

“As the water was rising very, very quickly, they only had about a foot of airspace left inside the elevator and it was completely closed, so officers pried the elevator open and rescued the two men,” spokesperson Katrina Arrogante told Global News.

She said the officers had to find a crowbar and swim through the basement to access the elevator.

Meanwhile, emergency crews were called to multiple scenes with vehicles trapped on roads and surrounded by water.

Three vehicles were stuck on Wilson Street near Dubray Avenue, east of Keele Street. However, the occupants were able to leave safely.

In downtown Toronto, the police marine unit was called in to help several people stuck in four vehicles near Lower Simcoe Street and Bremner Boulevard. There were no reports of injuries.

Residents in the downtown core and in midtown Toronto posted photos and video showing flooding on local roads.

The heavy rains the closure of several roads, including parts of the Don Valley Parkway and Lake Shore Boulevard West.

Toronto Fire Services (TFS) said water is approximately a metre deep on some roads and that crews are receiving reports of basement flooding.

TFS Chief Matthew Pegg said as of 11 p.m., firefighters were responding to approximately 98 active calls.

Residents wanting to report downed hydro lines and flooding damage are encouraged to contact the City of Toronto’s 311 line.

If you're waking up to a flooded basement, please remember that electricity and water don't mix. Don't use flooded appliances, outlets, switches or breaker panels until they have been checked by a qualified electrician. If your basement is flooded, power needs to be disconnected.
