LeBreton Flats Redevelopment

Development projects

Building LeBreton

The NCC is embarking on a process to create a renewed vision for a dynamic Capital destination and a complete community where people can live, work and play at LeBreton Flats. A Master Concept Plan for LeBreton Flats will be developed to guide development and will include:

  • signature public spaces and parks
  • mixed-use areas, including places for homes, employment, education and more
  • mobility networks and transportation infrastructure
  • spaces for possible major attractions

Having an overarching vision in the Master Concept Plan will enable the NCC to implement the plan in a strategically phased and coordinated manner, before moving to land transaction.

The NCC intends to seek municipal approval of the concept plan in 2020, with individual development applications requiring City approvals to follow.  

Public consultation on the master concept plan will be held in November 2019.

Ottawa Public Library and Library and Archives Canada joint facility

The joint facility will become a landmark destination built on the shared values of the partner institutions. The facility will deliver a rich customer experience through the Ottawa Public Library’s Central Library and Library and Archives Canada’s public services, exhibitions and events, which showcase Canada’s heritage. The joint programming and services will make this a truly unique offering in Canada. It will be a modern, world-class facility that will respond to rapidly developing technology, growing customer expectations and changing demographics.

The library’s location at 555 Albert Street, formerly 557 Wellington Street was selected through a site selection process and approved by City Council in February 2017. Council approved the Project, the partnership with LAC, the funding and the implementation plan on June 13, 2018.

City Council approved the Official Plan Amendment and Zoning By-law Amendment applications on July 11, 2018. The approvals showed a mixed-use development concept at 557 and 584 Wellington Street and 550 Albert Street, including a library at 557 Wellington Street. Additional information is available at

As part of the design process, the Ottawa Central Library will continue to engage the public and will bring forward a Site Plan application as well as applications to the City’s Urban Design Review Panel and the NCC’s Federal Land Use Design and Transaction Approvals. For more information, please visit the Ottawa Central Library website.


The Theia Partners and Dream Unlimited Corporation are redeveloping approximately 15 hectares of land formerly occupied by Domtar – a pulp and paper company – into a new mixed-use community. The development will be completed over a number of phases.

The Zibi development is located in both Ottawa and Gatineau on lands next to the Ottawa River just east of the Chaudière Falls. Zibi will be made up of seven districts, three of which will be in Ottawa on Chaudière and Albert Islands. 

In October 2014, Official Plan and Zoning By-law amendment applications in support of the development in Ottawa were approved by Council. In May 2019, the City of Ottawa approved the master site plan for the site. You can read parts one and two of the Domtar Lands Redevelopment Master Plan on

Over the next few years, the City of Ottawa will review detailed plans for each phase of the project through individual Site Plan Control applications. The first phase, now under construction at 320 Miwate Private, includes a six-storey residential building and a pedestrian plaza. Two other individual phases are currently proposed, including an eight-storey office building at 125 Zaida Eddy Private and a six-storey office building at 6 Booth Street.

History of LeBreton Flats

The neighbourhood of LeBreton Flats is located in downtown Ottawa, west of Bronson Avenue, east of the Trillium transit line, south of the Ottawa River and north of Albert Street.

Historically, LeBreton Flats was an industrial and working class neighborhood. In the early 1960s, the Government of Canada expropriated the lands to build an office campus and placed the lands in the custody of the National Capital Commission. For a number of reasons, the federal office campus was never built and LeBreton Flats remained vacant for decades.

The redevelopment of LeBreton Flats began with extensive decontamination of the soil and the construction of the Canadian War Museum in 2005. Soon after, new residents moved into the first new residential buildings in the area. Over the next two decades, many exciting projects in LeBreton Flats will help to transform the area into a thriving community again.

Please visit the National Capital Commission’s website to learn more about the history of LeBreton Flats.
