|This article is part of the Global Fossil Infrastructure Tracker, a project of Global Energy Monitor.|
Foothills System Gas Pipeline is a natural gas pipeline that exports gas from Western Canada to the western and midwestern United States. 
The pipeline runs from Caroline, Alberta, to Monchy, Saskatchewan. It also has pieces connecting existing TC Energy pipelines to the Canada/Idaho border.

The Foothills System Gas Pipeline is approximately 1240 kilometers in length and transports natural gas from an interconnect with the NOVA Gas Transmission Ltd. Pipeline near Caroline, Alberta through British Columbia and Saskatchewan. The Foothills BC system transports natural gas from the Western Canadian Sedimentary Basin (WCSB) to a point on the Canada/U.S. border near Kingsgate, British Columbia. At the border, the Foothills BC system connects to the Gas Transmission Northwest pipeline, which serves markets in the Pacific Northwest, California and Nevada. The Foothills Saskatchewan system transports natural gas from the WCSB to the Canada/U.S. border near Monchy, Saskatchewan. At the border, it connects to the Northern Border Pipeline, which serves markets in the U.S. Midwest. In 2016, export capacity at Kingsgate averaged 82.78 million cubic metres per day (2.92 billion cubic feet per day) and throughput averaged 56.08 million cubic metres per day (1.98 billion cubic feet per day). Throughput on Foothills Saskatchewan decreased in 2014 and 2015 as Canadian exports to the U.S. Midwest declined. Throughputs on Foothills BC have remained relatively steady.  Foothills represents approximately 2% of TC Energy's earnings, and in 2015 it earned a revenue of Can$178.9 million.
