Developing LeBreton Flats

Development projects

IllumiNATION LeBreton

The National Capital Commission (NCC) is looking to develop a 21-hectare site in LeBreton Flats, bound by Wellington Street to the north, Booth Street to the east, Albert Street to the south, and the O-Train Trillium Line to the west.

The NCC began the redevelopment process for the site in 2014. In December 2015, two proponents presented their development proposals to the evaluation committee. In November 2016, the evaluation committee chose RendezVous LeBreton Group’s (RLG) IllumiNATION LeBreton submission as the winning proposal.

The NCC and RLG are currently negotiating an agreement. When the agreement is complete, the NCC will submit it to the Government of Canada for approval. After the agreement is approved, RLG will submit development applications to the City for review. 

To learn more about RendezVous LeBreton Group’s proposal, visit the NCC’s website.  

Ottawa Central Library Project

Development of an inclusive, dynamic Central Library enabling creation and learning is a strategic priority for both Ottawa Public Library and the City of Ottawa. Following extensive planning and public consultation, the City of Ottawa will be building a new Ottawa Central Library to replace the Ottawa Public Library’s Main branch.

The Ottawa Central Library is being pursued as a joint facility with Library and Archives Canada (LAC), pending Government of Canada approval. The library’s location at 557 Wellington Street (corner of Albert Street and Commissioner 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:


Windmill Development Group 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 November 2016, the City of Ottawa draft approved the first stage of the master site plan for the site. When the City approves the second stage of the master site plan, it will include conditions for the development of the future phases. 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 Site Plan Control application was submitted to the City in the fall of 2015 and is still under review. The proposal includes a six-storey mixed-use building and a pedestrian plaza within the Chaudière West District. Please visit to learn more about this application.

Visit the Zibi website for more information about the Zibi development.

900 Albert

TIP Albert GP Inc. are redeveloping a key site located immediately south of Bayview Station at the intersection of the Confederation Line and Trillium Line.  Trinity Station is located on the south side of Albert Street, south of the Lebreton Flats Development site.

Upon full build out, Trinity Station will consist of a mix residential, office, and retail uses within three towers proposed to be 65, 56 and 27 storeys respectively, connected by a three storey podium. In total, approximately 1,241 residential units are proposed with 366,000 square feet of office space, 113,000 square feet of retail space, and six levels of underground parking.

Applications for an Official Plan and Zoning By-law amendment were considered by Council on July 10, 2018 and approved.  A related application for Site Plan Control is currently under consideration.

Visit the Trinity Centre website for more information.


Current construction

Combined Sewage Storage Tunnel (CSST)

The City is working to reduce the frequency of combined sewage overflows during major rainfalls on the Ottawa River by completing the 17 projects in the Ottawa River Action Plan (ORAP).

The Combined Sewage Storage Tunnel (CSST) is an ORAP project to construct two interconnected tunnels that will store surface runoff and wastewater until it may be treated and returned safely to the Ottawa River. The north-south tunnel will run under Kent Street from Chamberlain Avenue to behind the Supreme Court of Canada, and the east-west tunnel will extend from LeBreton Flats to Stanley Park. In addition to reducing overflows from entering the Ottawa River, the CSST will reduce the risk of basement flooding for several low-lying lands in Centretown and the Glebe and increase operational flexibility and redundancy to major collector sewers. Construction began in the summer of 2016, and the system will be commissioned in 2020.

O-Train Confederation Line

The O-Train Confederation Line is the first phase of Ottawa’s light rail transit (LRT) system. The 12.5-kilometre fully-electric line will extend from Tunney’s Pasture Station in the west to Blair Station in the east and will connect 13 stations to the existing OC Transpo bus network and the O-Train Trillium Line at Bayview Station. A 2.5-kilometre-long tunnel through the downtown will provide reliable and efficient transit service to residents and visitors to Ottawa.

The Confederation Line will open in 2018. For more information about the system and features, please visit

Booth Street Bridge Connectivity Improvement

A design solution has been confirmed that will improve connectivity and cycling safety on Booth Street between Albert Street and the intersection of the Sir John A. Macdonald Parkway.

This functional design solution, which features a mix of cycle tracks and bike lanes along Booth Street, will provide safe cycling connectivity within this important active transportation corridor to many current and future amenities in this area.

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.
