Building LeBreton
Master Concept Plan

Client National Capital Commission
Location Ottawa | Ontario | Canada

O2 Planning + Design is leading an interdisciplinary team of landscape architects, urban designers, engineers, district energy experts, and planners in the creation of an inspiring master concept plan for LeBreton Flats in Ottawa. Expropriated by the National Capital Commission (NCC) in the 1960s, this former industrial neighbourhood is advantageously located immediately south of Ottawa’s downtown core and presents a unique brownfield development challenge. 

Retained by the NCC to complete the master concept plan, O2 sees the project as an opportunity for a renewal and reinvigoration of LeBreton Flats that will change how Ottawans live, work and play in their city. Setting a bold carbon neutral standard, this Master Concept Plan will guide development over the next 25 to 35 years, laying a framework for how the public and private sector will work together to rebuild LeBreton Flats under the direction of the NCC. 

In this plan, four unique districts create a Capital destination and thriving mixed-use community that will celebrate liveability and placemaking year-round. These districts are brought to life by the Master Concept Plan’s strategies. Starting with comprehensive Parks and Public Realm Strategy, Land-Use Strategy, and Mobility Strategy, LeBreton Flats will be built out in a way that is both equitable and sustainable, setting precedents in affordability, carbon neutrality and recognition of Indigenous, cultural and heritage elements.

To make this happen, the master concept plan will be grounded in a strategic implementation approach supported by market feasibility, collaboration with partners to support timely progress, and generating social, environmental and economic returns through project completion and beyond for our client and the National Capital Region.
