Northern Border Pipeline

Natural Gas Icon


The Northern Border Pipeline connects natural gas reserves in the Western Canada Sedimentary Basin with communities in the Midwestern U.S. Along the way, it also receives and transports U.S.-produced natural and synthetic natural gas. In addition to providing day-to-day energy for American families and businesses, it offers sustainable employment and contributes substantial tax revenues to local and state governments.

TransCanada operates Northern Border Pipeline and effectively owns 13.4 percent through its 28.8 percent interest in TC PipeLines, LP through a general partnership with ONEOK Partners, LP.
