Harrington Lake

Harrington Lake is a federal heritage property in Pontiac, Canada, serving as the summer residence of the Prime Minister. The main building displays wooden frame construction with vertical boards, a stone chimney, dormer windows, and two flanking entrance porches.

Cameron Macpherson Edwards, a timber magnate from Ottawa, erected the main building in 1925. The federal government acquired the property in 1951 and has used it as an official retreat ever since.

The estate takes its name from the nearby body of water and functions as a private getaway for the sitting head of government. Visitors cannot enter the grounds, but the surrounding woods and waterways reflect how nature has long been valued here.

The National Capital Commission oversees the estate and its outbuildings, including a caretaker dwelling, a barn, and a tractor shed. The grounds are closed to the public because the site remains reserved as a private residence for the head of government.

The barn on the grounds contains experimental prefabricated concrete panels that were rare in the early days of the building industry in Ontario and Quebec. These panels show an early attempt to introduce new building methods to the region.
