The 266 km (165 mile) south section of the Peace River Mainline (part of the NGTL System) will be retired.

The Foothills System is a 1,241 km (771 mile) long network of pipelines comprising the Foothills B.C. and Foothills Saskatchewan lines.

The Project will include the construction of approximately 4 kilometres (km) of pipe 324 millimeters in diameter for transporting natural gas. It will parallel the existing Canadian Mainline, and will start at the Saint-Sébastien Meter Station near route 133 and end at a new proposed valve and receiver site in the municipality of Pike River, near Chemin Molleur.
