Trans Québec & Maritimes Pipeline (TQM) has been operational since 1982 and has operated a gas transmission system since 1982. The pipeline connects with the Canadian Mainline near the Ontario/Québec border to transport natural gas to the Montréal and Québec City corridor, and interconnects with the Portland Natural Gas Transmission System from the Northeast US.

Pipelines are the safest and most environmentally responsible way to transport natural gas and petroleum products over long distances.
