LeBreton Flats

Thank you for sharing your comments on the proposals to redevelop LeBreton Flats.

Both proponents presented their proposals at public consultations on January 26 and 27 at the Canadian War Museum.

We invited all Canadians to submit their comments on the two proposals to redevelop LeBreton Flats (below) by completing an online questionnaire. More than 7,900 people submitted comments during the two-week consultation period.

A report summarizing the input provided by the public will be submitted to the evaluation committee for consideration in its assessment of the proposals. The report will be made public in spring.

Evaluation Process

The evaluation committee includes renowned architect A. J. Diamond (Diamond Schmitt Architects) and professional planner and land economist Mark Conway (N. Barry Lyon Consultants), as well as the National Capital Commission’s (NCC) Chief Executive Officer, Executive Director of Capital Planning, and Director of Real Estate Transactions and Development.

In addition to the public input, the evaluation committee will also benefit from the technical review of each proposal by more than 20 subject matter experts. The experts—from the NCC, the City of Ottawa, the private sector and academia—provided their advice on decommissioning, transportation plans, servicing plans, sustainability strategies, economic development, and delivery models.

The evaluation committee will present its findings and recommendation to the NCC Board of Directors in the spring of 2016.

Once the NCC Board of Directors approves a preferred proponent, negotiations will begin, with the objective of reaching an agreement on the terms and conditions governing the future development of LeBreton Flats. The final agreement will be submitted to the federal government for approval.

Interim Vocation of LeBreton Flats

The NCC consulted the public last spring to advance an interim vocation to make recently decontaminated sites at the southwest and southeast corners of Booth and Wellington streets accessible to the public in summer 2016.
