Ottawa's Confederation Heights 25-year vision: federal office district to become transit-oriented mixed-use community

A sprawling federal office district in Ottawa is in line for a 25-year transformation. According to an October 30 report by Ontario Construction News, the Confederation Heights master plan, led by Build Canada Homes in collaboration with the City of Ottawa, would turn the area, now dominated by surface parking and mid-century office towers, into a compact, sustainable, transit-oriented mixed-use community.

At least 8,500 homes; heritage buildings in the mix

The master plan calls for a minimum of 8,500 housing units. Heritage buildings on the site are part of the conversation, including the building at 1500 Bronson and the Taxation Data Centre at 875 Heron Rd. Build Canada Homes lists the overall federal lands at about 188 hectares, roughly five kilometres south of downtown, and has been advancing the vision with Public Services and Procurement Canada since 2021, consulting the public, Indigenous communities and approval authorities.

Planning process and transport changes

The final draft of the master plan was presented at a public open house at the Hellenic Event Centre in January 2026, followed by an 'As We Heard It' report in March; the City of Ottawa's corresponding Secondary Plan advanced through 2026, setting the policy framework for land use, built form, heritage, public space and transportation. The plan also proposes reworking the existing road interchange system and studying a new active transportation bridge over Bronson Avenue, with an emphasis on low-carbon design, green infrastructure and pedestrian-oriented streets.

RA Centre's $100-million rebuild plan

The RA Centre, on Riverside Drive, is planning its own future. The Ottawa Business Journal reported in October that the centre eyes a $100-million plan to build a new facility that would include affordable housing. Its chief executive, Ian Fraser, wrote to the community about the master plan in an open letter in January.

What comes next

This remains a multi-decade vision: construction start dates, the sequencing of individual parcels and the final treatment of heritage buildings have not been announced. With Build Canada Homes now running the process, further details are expected to emerge, along with the city council approval process.
