Project update

As a result of competing projects in the downtown core that resulted in significant traffic restrictions and with the postponement of other City of Ottawa capital projects, a formal decision has been made to delay the Sparks Street Replacement project construction timeline to 2024. After further review and consultation with external stakeholders and community partners, Enbridge felt it was prudent to defer this work to a later time with the intention of providing an opportunity to better coordinate development and design work with key City of Ottawa stakeholders by 2024.

We remain committed to this project and pre-planning activities such as engineering and environmental field studies and consultation with Indigenous communities, municipalities, agencies, and other interested parties to ensure a mutually beneficial outcome is achieved.

Enbridge Gas Inc. (Enbridge) has retained Dillon Consulting Limited (Dillon) to begin an environmental study for the proposed Sparks Street Replacement Project (the Project) located in the City of Ottawa. The Project is required to replace a 900-metre (m) segment of vital natural gas main along Sparks Street in downtown Ottawa, as the existing nominal pipe size (NPS) 12-inch pipeline is approaching its life expectancy. The existing pipeline will be abandoned and replaced with a new segment of NPS 12-inch steel pipe. Enbridge has identified two potential replacement pipeline routes, including a preliminary preferred route and an alternative route.

The preliminary preferred route consists of approximately 1.1 kilometres (km) of NPS 12-inch intermediate pressure (IP) steel pipe along Albert Street, 900 m of NPS 4-inch IP polyethylene (PE) pipe along Sparks Street, and 175 m of NPS 12-inch IP steel pipe along Lyon Street North and Wellington Street. The alternative route consists of approximately 1.2 km of NPS 12-inch IP steel pipe along Slater Street and Bay Street, instead of Albert Street (see figure).

Once the study is complete, Enbridge will apply to the Ontario Energy Board (OEB) for approval to construct the Project. Pending regulatory approval, construction may begin in spring 2024.
