Ashbridges Bay Wastewater Treatment Plant

Discover the surprisingly fascinating story behind one of Canada's largest and oldest wastewater treatment plants, tucked along Toronto's eastern lakeshore. Ashbridges Bay Treatment Plant serves over 1.5 million residents, and its history is deeply tied to the city's public health evolution — including a critical response to a serious typhoid outbreak in the early 1900s. It's the kind of place that sounds unlikely on a night-out list, but guided tours offer a genuinely eye-opening look at urban infrastructure and environmental history that will change how you think about your city. Perfect for after work — drop in solo or bring a friend. No experience necessary.
