The massive flooding that struck the Greater Toronto Area on Tuesday was a “significant event,” highlighting the urgent need to intensify Canada’s efforts against climate change, according to Prime Minister Justin Trudeau.
The storm disrupted power for tens of thousands, flooded a major highway, and affected a key transit hub in Toronto amidst rainfall warnings across much of southern Ontario. This marked the second consecutive day of heavy downpours for the region.
Speaking in Toronto on Wednesday, Trudeau praised the work of first responders, city workers, and hydro staff. “It was a significant event,” he said. “I want you to know that we’re all committed to ensuring not only that people are supported through this but also that such events become increasingly rare in the future.”
Trudeau emphasized that more extreme weather events, like the Toronto floods, are expected due to climate change, underscoring the importance of investing in climate-resilient infrastructure. “The reality is that with climate change, we will see more extreme weather events,” he stated. “We need to continue to escalate our fight against climate change and invest in resilient infrastructure to handle future challenges.”
On Wednesday, cleanup crews were working to restore normalcy in the GTA. Tuesday’s deluge caused significant commuter disruptions, with severe flooding shutting down major routes and terminals, including Toronto’s Union Station, Don Valley Parkway, and Lake Shore Boulevard. These routes have since reopened after the floodwaters receded.
Toronto Hydro reported that around 3,300 customers were still without power on Wednesday morning, with restoration efforts ongoing.
