Northwest Winnipeg Natural Gas Project

The Northwest Winnipeg Natural Gas Project consists of a new 12- and 6-inch natural gas transmission pipeline to support and continue a reliable source of natural gas north of Winnipeg.

Project description

The Northwest Winnipeg Natural Gas Project provides a continual and reliable source of natural gas to customers located north of Winnipeg and provide operational flexibility in the Winnipeg transmission network.

The project extends the existing natural gas pipeline at Selkirk Avenue and the Perimeter, runs north to Stonewall and then travels east to connect with an existing pipeline near Selkirk, Manitoba. The pipeline located from Provincial Road #321 to Stonewall has a 6-inch diameter and the remainder of the project has a 12-inch diameter.


  • Final design: October 2014;
  • Public engagement: January to August 2015;
  • Filing of environmental assessment report: August 2015;
  • Construction: spring 2016;
  • In service date: January 23, 2017.


We have completed the construction of the natural gas pipeline and it is now operational.

Manitoba Hydro is planning to conduct post-construction testing on the Northwest Winnipeg Natural Gas Pipeline to check the coating integrity on the newly installed pipeline. This testing is done above grade without excavation and is part of the post-construction activities for the project.

We thank all those who participated in the public engagement process for the project.
