A combination of more extreme weather events and Toronto’s decades-old sewer system has exacerbated the threat of flooding. It’s expected there may be more occurrences in the coming years because of the effects of climate change. The City of Toronto is taking action and has several stormwater infrastructure projects included in a multi-year plan. Patrick McManus, executive director of the Ontario Sewer and Watermain Construction Association, and Dennis Cancian, executive director of the Ontario Formwork Association, discuss the situation and the work that’s planned.
