Beware of traffic disruptions along St. Laurent Boulevard this summer.

Enbridge Gas has announced it will be replacing close to 14.4 kilometres of its “natural gas distribution network.” Company spokesperson Chris Brennan outlined the project in a letter shared recently on the community listserv by the Manor Park Community Association.

“This year’s scope will include work along St. Laurent Blvd., from Ogilvie Road in the south (including work on Cummings Avenue and Brittany Drive), all the way up to Sandridge Road and along the Parkway into Rockcliffe Park,” noted Brennan, Enbridge Senior Advisor, Municipal & Stakeholder Affairs. 

Local residents should receive postcard notices alerting them as to when the work will start. Brennan notes the project “will be carried out in phases over the next several months.”

As a result of the work, lane reductions may be required along St. Laurent and other roads. Access to area homes and businesses “will be maintained,” he wrote. 

Vital line

A project synopsis posted on enbridgegas.com notes the St. Laurent Pipeline “is a vital part of Enbridge Gas’ distribution network. It supplies ”gas to close to 168,000 customers “directly and indirectly.”

“The St. Laurent Pipeline Replacement Project will involve the installation of approximately 13 km. of new 6-inch (15.2 cm), 12-inch (30.5 cm) and 16-inch (40.6 cm) extra high-pressure steel pipeline segments, approximately 4 km. of 4-inch (10.2 cm) and 6-inch (15.2 cm) diameter intermediate pressure polyethylene pipeline segments, and some ancillary facilities.”

Enbridge notes it first applied to the Ontario Energy Board (OEB) for approval in March 2021. After conducting further testing to determine the pipeline’s condition, the company submitted a construction application in 2024. The OEB approved the application March 18, 2025.
