News Release

January 25, 2024

The National Capital Commission (NCC) is pleased to announce today that it has agreed to an offer to lease with Canadian developers Avenue 31 Capital Inc. and Cogir for the development of a portion of the Flats District at LeBreton Flats.

With this offer to lease, the NCC is moving forward with the implementation of its LeBreton Flats Master Concept Plan. The Master Concept Plan offers a cohesive and multi-decade vision for the Building LeBreton project. It guides the transformation of LeBreton Flats into a diverse residential community supported by retail and employment opportunities where anyone can live, work and play.

Following the conclusion of a lease, Avenue 31 Capital Inc. and Cogir would develop four parcels of land (1.63 hectares) within the Flats District to create a new sustainable and inclusive residential-focused community. This next phase of development will deliver more than 900 much-needed homes in the core of the Capital, including affordable residential units and units with at least three bedrooms. The net-zero-carbon buildings will sit in a neighbourhood of pedestrian-friendly streets with transit and active transportation as the preferred modes of travel and will connect to a future district energy system.

This announcement builds on the success of the first phase of the Building LeBreton project – the Library Parcel – where 608 new residential units are soon to be constructed. Of these, 250, or 41%, are affordable units. The full development of lands in the Master Concept Plan will result in at least 25% of all the residential units to be used for affordable housing.

Next Steps

  • Over the course of 2024, the NCC will engage in lease negotiations with the proponent, which will also conduct its due diligence, including advancing design work for the development. Design for the Flats Phase development will be subject to the federal land use and design approval process.
  • The NCC and Avenue 31 Capital Inc./Cogir will aim to enter into a lease agreement by late 2024.
  • Construction of roads and buildings in the Flats Phase will begin following municipal approval of the NCC’s plan of subdivision, which is targeted for late 2025.
  • The agreement includes deadlines for the start and completion of development blocks within the Flats Phase to ensure timely completion and occupancy of all buildings.
