For more than 75 years, 24 Sussex Drive has served as the official residence of the Prime Minister of Canada and as a setting for diplomacy, public service, and decisions of national consequence. But following decades of deferred maintenance, the property is unoccupied and in critical condition.

On June 26, Prime Minister Mark Carney announced the launch of an independent national design-and-build competition to rehabilitate and modernise 24 Sussex Drive. The project will restore the property as a secure, accessible, sustainable, and functional official residence and working venue for Canada’s prime ministers, while preserving its defining heritage character.

The competition will be open to eligible Canadian firms, putting Canadian design excellence at the centre of the project. The Royal Architectural Institute of Canada (RAIC) will provide advice on the competition framework and has convened an independent jury of distinguished Canadian experts in architecture, heritage conservation, and design.
