R.C. Harris Water Treatment Plant

Constructed in the 1930s, this popular Doors Open site is Toronto’s largest water treatment plant, providing 400 million litres of safe drinking water daily. It’s also the largest ensemble of art deco structures in the city. Take a self-guided tour and explore the pump house and filter building, with staff available to answer your questions along the way. (Photo: Samuel Kolber)
