The Brunswick Pipeline is a 145-km natural gas transmission pipeline supplied exclusively by Repsol Energy Canada Ltd. from the Canaport™ Liquefied Natural Gas (LNG) receiving and re-gasification terminal  near Saint John, New Brunswick, to markets in Canada and the US northeast.  The 30-inch diameter, 145 kilometer natural gas transmission pipeline extends through southwest New Brunswick to an interconnection with the Maritimes & Northeast Pipeline (M&NP)  near St. Stephen, New Brunswick.

Being an open access pipeline, Brunswick is currently seeking opportunities to deliver natural gas to new customers along the pipeline.
