Enbridge Gas Ontario is enhancing the safety and reliability of its pipeline infrastructure by replacing approximately 14.4 km of its St. Laurent Pipeline currently located along St. Laurent Boulevard, Sandridge Road and Tremblay Road in the City of Ottawa. The St. Laurent Pipeline is a vital part of Enbridge Gas Ontario's natural gas distribution network in the National Capital Region. It directly and indirectly supplies natural gas to approximately 168,000 homes, businesses and institutions in Ottawa and the surrounding area, including in Gatineau, Quebec. Three of every four homes in Ottawa use natural gas. The St. Laurent Pipeline Replacement Project will involve the installation of approximately 13 km of new 6-inch, 12-inch and 16-inch extra high-pressure steel pipeline segments, approximately 4 km of 4-inch and 6-inch diameter intermediate pressure polyethylene pipeline segments, and some ancillary facilities. The St. Laurent Pipeline Replacement Project is a multi-component construction project that will be conducted in phases beginning in April 2025 and continuing through 2026.
Due to permitting timelines and concurrent projects in the area, Enbridge Gas Ontario will split this project into components. The timing of these components is subject to change due to inclement weather and/or other factors.
