Prime Minister Mark Carney has unveiled an ambitious plan to restore the long-neglected official residence at 24 Sussex Drive through a national design-and-build competition and a non-partisan fundraising campaign.

The announcement, made on June 26, 2026, marks a significant step toward returning the historic Ottawa property to full service after years of deterioration that rendered it uninhabitable.

Background on 24 Sussex Drive

Built in 1868, 24 Sussex Drive has served as the primary residence for Canadian prime ministers since 1951. The property has faced mounting maintenance challenges, including structural issues and outdated systems, leading to its closure to residents in recent years.

Successive governments have grappled with the costs and complexities of rehabilitation, leaving the building vacant and symbolic of broader infrastructure challenges facing heritage sites across the country.

Details of the National Design Competition

The competition will be open to eligible Canadian design firms, with the winning team responsible for both design and construction. An independent panel of experts, chaired by renowned architect Moshe Safdie, will adjudicate entries, advised by the Royal Architectural Institute of Canada.

The winning proposal is expected to be announced by Canada Day, July 1, 2027. The project aims to create a secure, accessible, sustainable, and functional official residence and working venue.

Fundraising Campaign Led by Rideau Hall Foundation

To minimize costs to taxpayers, the Rideau Hall Foundation will lead a national, non-partisan fundraising effort with the goal of covering all or most of the project expenses. The federal government will continue to cover security-related costs during the restoration.

Prime Minister Carney emphasized that “24 Sussex Drive will be built by Canadians for Canadians,” highlighting the importance of preserving this national landmark through community involvement.

Stakeholder Perspectives and Reactions

Heritage advocates and architectural organizations have welcomed the initiative as a positive development for Canadian design excellence and preservation. Public reaction has been largely supportive, with many viewing the competition as an opportunity to showcase national talent.

Opposition voices have raised questions about timelines and accountability, but the cross-partisan nature of the fundraising effort has been noted as a constructive approach.

Implications for Heritage Conservation

The restoration represents a broader commitment to maintaining Canada’s built heritage. By prioritizing sustainability and accessibility, the project sets a precedent for future government-led heritage initiatives.

Experts note that modernizing 24 Sussex Drive while respecting its historic character will require innovative solutions in materials, energy efficiency, and security integration.

Timeline and Next Steps

Following the announcement, detailed competition guidelines will be released in the coming months. Canadian firms are encouraged to prepare submissions that balance heritage preservation with contemporary needs.

The independent jury process is designed to ensure transparency and merit-based selection, with public updates expected throughout the evaluation period.

Future Outlook for the Residence

Once restored, 24 Sussex Drive is expected to resume its role as both a private residence and a venue for official functions. The project is anticipated to enhance the property’s longevity and operational efficiency for decades to come.

Long-term benefits include reduced maintenance costs and a renewed symbol of Canadian governance and design innovation.
