Enbridge Gas must relocate and construct a segment of its 20-inch high-pressure steel natural gas pipeline and related infrastructure in Toronto’s Port Lands in support of Waterfront Toronto’s Port Lands Flood Protection Enabling Infrastructure Project.

This pipeline is part of the Kipling Oshawa Loop (KOL) that provides natural gas service to downtown Toronto, including customers such as hospitals and Billy Bishop Toronto City Airport that depend on reliable energy sources for daily operations.

Relocation and construction of the pipeline will be completed in two phases:

  • Phase I: construction of an above-ground temporary bypass of the pipeline on the sidewalk south of the new Lake Shore Bridge over the Don River at Lake Shore Boulevard East and Don Roadway (approx. 209 metres).
  • Phase II: relocate the pipeline from its temporary location to its permanent location on the north side of the Keating Railway Bridge within a new utility corridor (approx. 166 metres).

Project updates

A Leave to Construct (LTC) application was filed with the Ontario Energy Board (OEB) on Feb. 24, 2022 and the notice of approval was provided to Enbridge Gas from the OEB on July 7, 2022.

Construction began in June 2023 and the pipeline is expected to be fully in-service by the end of 2024.

Periodic traffic lane reductions in the area of Don Roadway and Lake Shore Boulevard East are required to accommodate this work. These traffic restrictions are subject to change and will be updated here once confirmed.

  • From October 13 to 23 2023, one westbound lane of Lake Shore Boulevard East, west of Cherry Street, will be periodically occupied.
  • From October 16 to 19, 2023, Lake Shore Boulevard East will be reduced to one lane in each direction at Don Roadway.
  • From October 16 to 22, 2023, Don Roadway will have reduced lanes north of Lake Shore Boulevard East.
  • From October 19 to 22, Lake Shore Boulevard East will be reduced to one shared lane for eastbound and westbound traffic.

Indigenous and community engagement

The collective input from key stakeholders including Indigenous communities, government agencies, municipalities, stakeholders, the public and landowners play an integral role in the route and site selection process.

Prior to construction, public input is sought to ensure that the community is advised of the proposed project and involved in the decision-making process. Public consultation and engagement are key components of the project’s Environmental Report.

The consultation program also helps to identify and address stakeholder concerns and provide the opportunity for meaningful participation in the project review and development process. Input received from the public information session is used to help finalize the project and mitigation plans that may be implemented during construction.

Once the Leave to Construct (LTC) application is made to the Ontario Energy Board, any party with an interest in the project, including members of the public, may participate in this process.

Public notification

Newspaper advertisements

The notice of study commencement and virtual open house for NPS 20 Waterfront Relocation Pipeline project was published in The Toronto Star during the week of Oct. 25, 2021.

Virtual public information session

A two-week virtual information session occurred between Nov. 1 and Nov. 14, 2021 and was promoted with social media ads targeted to residents in the area near the project. Public feedback was integrated into the environmental report and project planning process.

The presentation boards are available for viewing below:

Regulatory information

The NPS 20 Waterfront Relocation Pipeline project is regulated by the Ontario Energy Board (OEB), an independent government agency that regulates the electricity and natural gas sectors. After a public review and hearing, the OEB approved the Leave to Construct application. All regulatory files about the project are available in this section.

Environmental report

In accordance with the OEB's “Environmental Guidelines for the Location, Construction and Operation of Hydrocarbon Pipeline and Facilities in Ontario, 7th Edition 2016”, Enbridge Gas retained the services of Stantec Consulting Ltd., an independent environmental consultant, to complete an environmental assessment for the project.

The environmental assessment identifies potential impacts of the proposed project on the social, economic and natural environments; local and/or provincial concerns regarding the proposed project; determines the preferred routing of the pipeline; and gathers input from government agencies, stakeholders, Indigenous communities, affected landowners and the public. It may also include mitigation and monitoring measures to minimize the potential impacts of the natural gas pipeline and associated facilities on the environment. The data, analysis and results of the environmental assessment are detailed in the Environmental Report.
