Flooding Causes Power Outage in Toronto, Affecting Thousands

On July 16, 2024, Toronto experienced a severe storm that led to widespread flooding and significant power outages across the city. The torrential downpour caused major disruptions, affecting thousands of residents and businesses.

The Storm

The storm brought an unprecedented amount of rainfall, with Environment and Climate Change Canada reporting 97.8 millimeters of rain at Pearson International Airport and 83.6 millimeters in downtown Toronto within a few hours. This deluge resulted in flooding in various parts of the city, including major roadways like the Don Valley Parkway, where some vehicles were partially submerged.

Affected Areas

The flooding and power outages were most severe in the western half of Toronto, stretching from the Mississauga city limit to Spadina. Other areas experienced spotted outages, but the western regions were the hardest hit. Major roadways like the Don Valley Parkway were heavily flooded, causing traffic disruptions and vehicle submersions.

Power Outages

The flooding caused extensive damage to the city’s power infrastructure. Toronto Hydro reported that over 165,000 customers were without power at the peak of the outage. The outages were concentrated in the western half of the city. Stretching from the Mississauga city limit to Spadina, with spotted outages in other areas.

Hydro One, which supplies power to Toronto Hydro, experienced issues at one of its transmission stations, exacerbating the situation. Crews worked tirelessly to restore power, with many areas expected to have electricity back by late evening.

Response and Recovery

Toronto Mayor Olivia Chow praised the efforts of city and TTC crews who worked through the night to manage the situation and restore normalcy. She urged residents dealing with flooding in their homes to contact the city’s 311 line and advised people to stay away from rivers and ravines due to hazardous conditions.

Prime Minister Justin Trudeau also commented on the storm, thanking Toronto’s first responders, city, and utility workers for their swift action. The Toronto and Region Conservation Authority reported that water levels in the Don River were falling, but cautioned that some rivers were still experiencing higher flows, making conditions dangerous.
