Approximately 346,178 kilometres of natural gas pipelines run across Canada.  Transmission pipelines, like the Brunswick Pipeline, make up approximately 81,854 kilometres of that total.  Transmission pipelines run through both urban and rural areas in Canada.

The design and construction of the Brunswick Pipeline and all transmission pipelines in Canada are guided by regulations set by the National Energy Board and the Canada Standards Association.  These standards regulate operating pressures, pipe wall thickness, protective pipe coatings, depth of burial, public safety and system integrity management, and are considered among the highest industry standards in the world.
