R.C. Harris Water Treatment Plant

On the shore of Lake Ontario in Toronto’s Beaches area, the R.C. Harris Water Treatment Plant pairs working city infrastructure with striking Art Deco architecture. The plant is known for its grand exterior, while the surrounding lawns and paths give you room to walk, picnic or take photographs beside the water. Come for the architecture and stay for the lake views, especially near sunset. The facility is operational, so plan to enjoy the grounds rather than expect general access to the interior.

An Art Deco landmark on the waterfront

The R.C. Harris Water Treatment Plant is an operational facility in Scarborough, on the shore of Lake Ontario. It is also an architectural landmark, known for its Art Deco design and imposing exterior. The plant is named after a long-time commissioner of Toronto’s public works.

The site brings together working infrastructure and public outdoor space. You can admire the building from the surrounding grounds, where lawns, mature trees and paths open toward the lake. The plant is the largest of Toronto’s four water treatment facilities and supplies an average of 400 million litres of drinking water.

Walks, views and access

The grounds are a place to stroll, sit on the grass or take photographs with the building and lake in view. Paths around the property are especially appealing later in the day, when the setting sun falls over Lake Ontario. There is also a small beach access nearby.

The plant is not generally open for interior visits. Doors Open Toronto is an exception, with special access to parts of buildings that are usually closed. Parking nearby can be limited, so read street signs carefully and do not park in permit-only areas.
