About TQM

The Trans Québec & Maritimes Pipeline (TQM) was founded in 1980 and is owned equally by subsidiaries of two major Canadian companies in the energy industry, Énergir and TC Energy. TQM’s system is operated by TC Energy and supplies natural gas through Énergir to residential, commercial and industrial customers in Québec, as well as supplies downstream customers in the Northeastern United States and Atlantic Canada.

Safe and reliable natural gas delivery

The 649-kilometre (km) system includes 37 delivery points and four compressor stations and is interconnected to two storage sites and two renewable natural gas receipts. The system transports natural gas from an interconnect with TC Energy’s Canadian Mainline at Les Cèdres, Québec to a point near Québec City, in the municipality of Lévis on the south shore of the St. Lawrence River. Additionally, the system extends from Terrebonne, north of Montreal, to East Hereford, Québec on the border with New Hampshire, where it interconnects with the Portland Natural Gas Transmission System. In 2022, TQM integrated an existing pipeline into its system, from an interconnection with TC Energy’s Mainline in Sainte-Anne-de-Sabrevois, Québec to Shefford, Québec where it interconnects with the existing TQM pipeline.

Safe and Reliable Natural Gas Delivery

The system is also interconnected with Énergir’s distribution system and provides approximately 50 per cent of the natural gas supply to Énergir. TQM crosses the territory of 83 municipalities and the property of approximately 1,900 landowners.

TQM is regulated by the Canadian Energy Regulator (CER) with regard to its transportation tolls and its facilities.
