Metrolinx will continue to move ahead with the plans to extend GO rail service from Durham College Oshawa GO station through to Bowmanville, with four new stations – Thornton’s Corners East, Ritson Road, Courtice and Bowmanville.

The Ontario environment minister issued a Notice to Proceed following completion of a Transit Project Assessment Process (TPAP) for the Lakeshore GO East Extension to Bowmanville. The TPAP is an environmental assessment that ensures any potential negative impacts to the natural, social, cultural and economic environment are protected.

Bowmanville map“We are thrilled that this project continues to achieve major milestones, bringing this extension one step closer to fruition,” John Henry, Regional Chair and Chief Executive Officer for The Regional Municipality of Durham, said in a statement. “Students, residents and visitors will be able to seamlessly travel across Durham and beyond, creating more connected communities.

In June 2023, Metrolinx announced Bowmanville Construction Partners (BCP) as the construction manager that will come on board to help inform the detailed design and provide construction management advice for the Bowmanville Extension project. This procurement process began in April 2022. BCP is a general partnership between Ledcor CMI Ltd. and Dragados Canada Inc.

Metrolinx will continue with plans to extend the Lakeshore East GO Line nearly 20 kilometers to Bowmanville.

  • The project includes:
  • New track and signal infrastructure
  • Seven new bridges, including a new rail alignment over Highway 401
  • Bridge reconstruction and existing bridge modifications
  • Utility relocations
  • At-grade crossing upgrades

Overall planned expansion projects are transforming the GO rail network into a modern two-way all-day, rapid transit system, providing more frequent service, more stations, cleaner technology, and more connections.
