The federal government is holding a competition to renovate 24 Sussex Drive, the Prime Minister's official residence in Ottawa. Companies interested in the project have until August 15 to register. The Globe and Mail reported that Prime Minister Mark Carney launched the process in late June.

PSPC spokesperson Jean-Francois Létourneau said more details will come in the fall. The government expects to choose a winning company by Canada Day 2027.

Here's how the competition works: instead of the government designing the building and then asking companies to bid on construction, it's asking companies to propose both the design and the construction work together. Thirteen companies have already said they're interested.

Architects will have a say in which design wins. The Royal Architectural Institute of Canada is running the competition, with a panel of architects led by Moshe Safdie — who designed Habitat 67 and the National Gallery of Canada — reviewing the design proposals.

Where's the money coming from? The Rideau Hall Foundation, the charity that supports the Governor General's residence, is trying to raise $50 million in donations. Two former prime ministers are helping with the fundraising: Jean Chrétien and Stephen Harper, who are from different political parties. That's unusual — they're putting aside party lines to help get this project done.

24 Sussex has been empty since 2015. Prime ministers have been living in a smaller house on the Rideau Hall grounds instead. In 2020, the government told Parliament that both 24 Sussex and Harrington Lake — the PM's country home — were badly deteriorated and needed major work. Documents from that time showed the damage was serious.

Why involve architects and private fundraising? Past attempts to fix up 24 Sussex have been politically complicated. Governments worry about the public seeing the Prime Minister's residence as a luxury project paid for by taxes. By having architects choose the design and raising money from private donors, the government spreads responsibility for the decision. Getting Chrétien and Harper involved also shows this isn't just about the current prime minister.

Two things need to happen for this plan to work. First, the August 15 deadline needs to bring in a good list of serious bidders. Second, the $50 million in donations needs to keep up with actual construction costs, which often go up once contracts are signed. When the government releases more details in the fall, it will explain how many of the thirteen interested companies move forward and how the decision between design and cost will work.
