Canada Launches National Competition and Fundraising Campaign to Restore 24 Sussex Drive

The Canadian government has initiated an independent national design-and-build competition to restore 24 Sussex Drive, the official residence of the Prime Minister, after years of deferred maintenance left the building uninhabitable. Prime Minister Mark Carney announced the project on 26 June 2026, standing outside the empty mansion in Ottawa. The competition, which is open to Canadian architecture firms, will be overseen by the Royal Architectural Institute of Canada (RAIC) and an independent jury chaired by architect Moshe Safdie. The winning design is set to be announced on Canada Day, 1 July 2027.

The restoration initiative includes a national, non-partisan fundraising campaign, led by the Rideau Hall Foundation (RHF), a charitable organization with experience in large-scale national campaigns. The campaign aims to raise all or most of the required funds, minimizing the direct cost to government. Donations will be accepted from individuals and philanthropic organizations, but not corporations, and the donor list will be made public. Carney emphasized that Canadians have "a sense of ownership and responsibility" over the home, describing it as "a symbol of the nation."

The precise cost of restoration remains uncertain, as it will depend on the final design, but estimates have ranged considerably. The National Capital Commission (NCC), which manages federal heritage properties, has cited C$40 million as a baseline for renovations and upgrades, while other estimates place the cost north of C$100 million. The reluctance of previous governments to allocate taxpayer funds for the project has contributed to decades of inaction, leading experts and observers to refer to the residence's condition as a "national embarrassment."

24 Sussex Drive was built in 1868, acquired by the government in 1949, and designated a Classified Federal Heritage Building in 1986 due to its role in Canadian political history and its architectural significance. Since its refurbishment in 1950, it has housed every prime minister from Louis St. Laurent in 1951 to Stephen Harper in 2015. However, no comprehensive rehabilitation has been undertaken in over 75 years. The residence has hosted numerous historic events and international visitors, including Queen Elizabeth II, John F. Kennedy, and Winston Churchill.

The building has been vacant for more than a decade. Former prime minister Justin Trudeau and current Prime Minister Carney have lived at Rideau Cottage, a smaller government-owned residence on the grounds of Rideau Hall, due to the unsafe conditions at 24 Sussex. The state of disrepair includes rodent infestations, mould, asbestos, lead, cracked windows, water damage, failing plumbing, and outdated electrical systems considered fire hazards. In 2023, the NCC closed the building for safety reasons. By 2024, hazardous materials and rodents had been removed, and essential systems such as heat pumps had been installed, but the residence remained unfit for occupation.

Political caution has been a significant factor in the prolonged neglect. In the 1980s, then-prime minister Brian Mulroney faced public backlash for renovations, a controversy dubbed “Gucci-gate.” Since then, successive leaders have been wary of appearing self-indulgent, especially as costs climbed and public scrutiny intensified. Reports as far back as 1984 labeled the house in “advanced disrepair,” and a 2008 auditor general’s report warned that delays would only worsen deterioration and increase costs. Political leaders have frequently cited more pressing national priorities when questioned about restoring the residence. Conservative Leader Pierre Poilievre recently stated, “When I see the homelessness on our streets and I see the young people who are desperate to start families but can’t get a house to do it, I just think the last thing on our minds should be 24 Sussex Drive.”

The debate over the fate of 24 Sussex has thus reflected broader concerns about government spending, symbolism, and the stewardship of public assets. The issue has transcended partisan lines; both Liberal and Conservative governments postponed major repairs. In 2019, Conservative criticism focused on what they characterized as a “failure” by the Trudeau government to resolve the matter, while in 2026, Conservative House Leader Andrew Scheer objected to the attention given to the residence during a national housing crisis.

Despite these challenges, the new plan represents a significant shift in approach. The design competition is intended to ensure that the restored residence is secure, accessible, sustainable, and reflective of Canadian heritage. The independent jury includes experts in architecture, heritage conservation, and design. In addition to Safdie, members include Carol Bélanger, Nicolas Demers-Stoddart, Omar Gandhi, Mamie Griffith, Patricia Kell, and Brigitte Shim. The selected team will be responsible for both the design and construction, with an emphasis on feasibility and cost management.

In the interim, Rideau Cottage remains the Prime Minister’s residence, though it is considered inadequate for hosting major functions or heads of government. Former governor general Mary Simon has publicly stated that it is inappropriate for a prime minister to reside on the grounds of Rideau Hall, underscoring the need for a dedicated official residence.

The restoration of 24 Sussex is framed by government officials and supporting organizations as a matter of national stewardship and identity. Carney remarked, “We will restore 24 Sussex Drive to a standard worthy of the country it serves.” Minister of Government Transformation Joël Lightbound added that the goal is to “restore it responsibly, manage costs carefully, and ensure taxpayers get value for money.” Johanna Hurme, president-elect of the RAIC, described the initiative as an opportunity to “showcase the design excellence, creativity, innovation, and expertise that define Canadian architecture and engineering.”

The RHF’s Teresa Marques stated that the campaign “reflects the Rideau Hall Foundation’s nation-building mandate to strengthen and celebrate the institutions that shape our shared public life.” Joseph Clarke, associate professor of architecture at the University of Toronto, characterized the building as “a living record” of Canadian history and architectural evolution, and expressed relief that restoration efforts are finally underway.

The competition and campaign mark a turning point after years of indecision. While the ultimate cost and timeline remain to be determined, the process is intended to address both the symbolic and practical needs of Canada’s national leadership. As Carney stated, “Canadians rightly expect their leaders to take decisions where the benefits may only be realised long after they are in office. Good stewardship demands it, Canadians rightly expect it, and the future of our institutions depends on us leaving them better than we found them.”
