The Canadian Mainline is 14,114 km (8,770 mile) in length and safely carries natural gas from the Western Canada Sedimentary Basin (WCSB) to Ontario and beyond. The map depicts the pipeline's southeastern section in the province of Ontario.

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

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.

The Project consists of a 206 kilometre (km), 42-inch pipeline, two compressor stations, and 14 meter stations. It will begin at a the northern point of the existing Saturn section of the Groundbirch Mainline at 14-21-80-20-W6M and terminate at the Blair Creek Receipt Meter Station located in Unit 30, Block K, Group 94-G-7.
