The National Capital Commission (NCC) and Capital Sports Development Inc. (CSDI) have signed the agreement of purchase and sale for land parcels totalling approximately 4.5 hectares (11 acres) for a new events centre and a mixed development project at LeBreton Flats. We have entered this agreement with Capital Sports Development Inc. (CSDI), a group led by the owners of the Ottawa Senators NHL hockey team. This agreement reflects a shared vision that bringing a major events centre to anchor a new downtown district in LeBreton Flats will create a premier destination for residents and visitors.
With the agreement of purchase and sale finalized, both parties can proceed with the next steps in the project. These include zoning, design and approvals, as well as decontamination of the land parcels to prepare for construction.
The latest on the project
On August 11, 2025, the NCC and CSDI entered into an agreement of purchase and sale of approximately 4.5 hectares (11 acres) of land to bring a major events centre and arena district, including a mixed-use development project, to LeBreton Flats.
The agreement lays out obligations for both parties on items such as decontamination of the land parcels and building of infrastructure elements crucial to the success of the project.
CSDI is proposing to build an NHL hockey arena and events venue, a new pedestrian and cycling bridge in the Preston corridor, and a mixed-use development at Parcels A1 to A5 of the LeBreton Flats Master Concept Plan. The project would be located on Albert Street, between City Centre Avenue and east of Preston Street.
