Tunney’s Pasture redevelopment project

Learn about the forward-looking project to transform the federal buildings and lands of Tunney’s Pasture into a vibrant, sustainable, mixed-use urban community in the nation’s capital.

Project overview

Project description

Located on the western edge of Ottawa’s downtown core, Tunney’s Pasture is a 49-hectare (121 acres) federal office employment node.

Master plan

The NCC approved the Tunney’s Pasture Master Plan (TPMP) in 2014. The TPMP was part of a strategic long-term planning exercise to recognize the untapped development potential of the site.

Implementation of Master plan

The implementation plan has evolved since the TPMP was approved in 2014. The plan will provide more detailed analysis of the building and infrastructure requirements and guide investment decisions. It will define the lands to be retained for office accommodation and the surplus land for residential, commercial, and community uses. It will also provide guidelines on sustainability, accessibility and urban design for the redevelopment that line up with the Federal Government objectives.

After completion, the site will become a sustainable and accessible mixed use community that is fully integrated with surrounding neighbourhoods. It will provide amenities for the broader community as well as future residents and employees of Tunney’s Pasture.

As part of the planning process, we are collaborating with the Canada Lands Company (Canada Lands) on the Tunney’s Pasture – Vision to Reality project. While PSPC will continue to lead on all elements of the redevelopment related to Federal office accommodation, Canada Lands will be the lead on all residential and community developments at Tunney’s Pasture.

• PSPC will continue to lead engagement with all Indigenous partners
• Canada Lands will lead all engagements with surrounding communities and elected officials
• PSPC and Canada Lands will jointly engage all relevant stakeholders, including community groups, the NCC and the City of Ottawa

These engagements will allow us to share development objectives and provide opportunities to receive input from a variety of perspectives.
