The Trans Québec & Maritimes Pipeline (TQM) was founded in 1980 and is owned equally by subsidiaries of two major Canadian companies in the natural gas 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 downstream customers in the Northeastern United States and Atlantic Canada.
The 574-kilometre (km) system includes 31 delivery points and three compressor stations, with another station currently under construction. 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. Starting in July 2022, TQM will integrate an existing pipeline into its system, from an interconnection with TC Energy’s Mainline in Sabrevois, Quebec to Shefford, Québec where it will interconnect with the existing TQM pipeline.
The system is also interconnected with Énergir’s distribution system and provides approximately 60 per cent of the natural gas supply to Énergir. TQM crosses the territory of 75 municipalities and the property of approximately 1,700 landowners.
TQM is regulated by the Canada Energy Regulator (CER) with regard to its transportation tolls and its facilities.
