GO Trains between Hamilton and Toronto delayed due to flooding in GTA

A severe storm has left many of Toronto’s streets flooded, including the Don Valley Parkway, and Toronto Hydro said more than 167,000 customers are without power.

Crews are working on the outages but they do not have an estimated restoration time, Toronto Hydro said. Residents are asked to avoid downed wires and call 911 if they see any.

Environment Canada had issued a rainfall warning for the city on Tuesday morning, with a risk of thunderstorms continuing in the afternoon and evening. However, the warning was no longer in effect by the early afternoon. 

Roadways in many parts of the city were flooded, while TTC and GO Transit service was also disrupted. The Don Valley Parkway is blocked in both directions due to flooding. 

Toronto Fire said they have rescued 12 people from flooding on the Don Valley Parkway, including one person from their car’s roof. 

Crews have been responding to an extremely high number of calls related to flooding and elevator entrapments, Toronto Fire said.

Up to 110 millimetres of rain was expected to fall on Tuesday, with rainfall rates of 40 mm/h possible at some points, Environment Canada said. 

“Heavy downpours can cause flash floods and water pooling on roads. Localized flooding in low-lying areas is possible. Watch for possible washouts near rivers, creeks and culverts,” the rainfall warning said.

The Toronto and Region Conservation Authority (TRCA) issued a flood warning on Tuesday afternoon, saying that the total rainfall expected could create “hazardous conditions” near bodies of water, including slippery and unstable river banks. 

All shorelines, rivers and streams in the GTA should be considered dangerous as heavy rainfall could result in higher flows, erosion and rapidly changing water levels, the (TRCA) said.

“Please exercise caution if you must be around any bodies of water, rivers or streams as well as the Lake Ontario shoreline,” the TRCA said. 

Mayor urges people to be careful amid flooding

Speaking on Tuesday afternoon, Mayor Olivia Chow said the city is “massively investing in the state of repair so that there is less flooding going forward.” 

“Please be safe. Don’t drive on flooded roads and stay away from streams, rivers [and] shorelines,” she said.

Asked why the Don Valley Parkway wasn’t closed earlier to drivers to prevent cars from driving through flooding roadways, Chow said she doesn’t know.

The relentless downpours caused significant flooding in some parts of the city, especially in low-lying areas close to Lake Ontario.

Near the corner of King Street W. and Atlantic Avenue W., a stretch road historically prone to flash flooding, abandoned heavy construction machinery and a pickup truck were seen half submerged in water.

Several inches of water also accumulated in areas of Union Station, the city’s biggest transit hub, with water from inside cascading down exterior staircases.

The scenes were reminiscent of the major flood that hit the city in July 2013.

Peel police warned drivers that downpours were causing manhole covers to lift out of place. They urged drivers to be cautious and use the full headlight system on their vehicles.

Toronto Pearson International Airport said a section of Convair Drive, near the airport, was closed due to flooding. However, there was no flooding at the airport and there are no flight disruptions reported.

People travelling to the airport are advised to map out their route to avoid any road closures and give themselves extra time to arrive safely, the airport said.
