Bowmanville GO Expansion Project

Bowmanville GO Rail Business Case Completed

Durham MPPs Continuing to Work to Move GO Rail Service to Bowmanville Forward 

February 13, 2020

Bowmanville — Today Lindsey Park, MPP for Durham, along with Lorne Coe, MPP for Whitby and David Piccini, MPP for Northumberland-Peterborough South announced that Metrolinx is making progress towards extending GO Rail service from Oshawa to Bowmanville.
Metrolinx has now completed the updated Initial Business Case (IBC) for the Lakeshore East Extension to Bowmanville. As part of the updated IBC, four options were assessed, and Metrolinx is recommending to its Board that Option Two be advanced.

This option proposes to follow the CP rail line north of the 401 and include two-way, all-day service to Bowmanville.  The rail would extend through the current Oshawa GO Station connecting to Canadian Pacific (CP) Railway’s General Motors (GM) spur line to cross Highway 401, and connect to CP’s Belleville Subdivision – the rail line on the north of the 401 to make its way to Bowmanville.

This rail service is proposing to operate express between Union and Pickering GO station, and make all stops between Pickering GO station and Bowmanville, including at proposed new station sites at Thornton’s Corners East, Ritson Road (the old Knob Hill Farms), Courtice and Bowmanville – four additional stops.
Pending the Board’s recommendation, Metrolinx will advance the project to the Preliminary Design Business Case. The timing will be further refined and developed through this design phase and through discussions with CP Rail.
This is another important step completed in the process that brings Durham Region closer to receiving increased access to transit in a cost-efficient way, while helping people get where they need to, when they need to get there.
“Expanding GO Rail service east of Oshawa will make it easier for Durham residents to get to work, school, and play, and back home to their loved ones,” said Lindsey Park, MPP for Durham. “Today’s update means we are another step closer to making this a reality.  Once the recommended alignment is approved by the Metrolinx Board, I will be pressing the Ontario government to get this project funded and built.”


  • As Metrolinx does not own the rail corridor between Oshawa and Bowmanville, expanding GO rail service beyond Oshawa on the Lakeshore East line depends on the successful outcome of negotiations with freight rail partners.

  • The Business Case process is an industry best-practice for project planning, giving decision-makers, stakeholders and the public a transparent, evidence-based analysis of proposed options.

  • The Initial Business Case is a planning document that outlines the reasons for a proposed investment, such as expanded GO rail service, proposed options for implementing the investment, and an evidence-based analysis of the benefits and costs of each option.

We have been waiting for the GO Train to Bowmanville for decades. It’s time to get this project done.

Here is what MPP David Piccini and I wrote to the Minister of Transportation Jeff Yurek today.

RE: Bowmanville Expansion Project

Dear Minister Yurek –

We are writing to share our thoughts about the GO Bowmanville Expansion Project following comments made by Metrolinx yesterday and to express our desire to see GO expansion to Bowmanville in a viable, expedited and cost-effective manner. 

On December 4, 2018, MPP Park wrote to urge you to press on with negotiations required to use the necessary rail lines and prepare the final design of the Project. We were pleased to learn Metrolinx has been working over the last number of months to prepare new design options for your consideration. 

It is shocking to hear that the new leadership at Metrolinx has found that the plan proposed by the last government would take years longer than the stated timelines, result in only four peak trains (not all­ day service) and cost twice as much as previously estimated. It is unfortunate that the Liberals recklessly announced their plan before the feasibility, preliminary design and cost estimates were fully completed. That is not how a responsible government would deliver real transit relief to commuters. 

The transparency Metrolinx is now offering the people of Durham Region, as it reviews better ways of expanding GO Train service past Oshawa to Courtice and Bowmanville, is very much appreciated. For too long, transit decisions were made behind closed doors with minimal publicly available information on the value being obtained for taxpayers’ money. With this new information, we urge you and the team at Metrolinx to evaluate the options and determine which will result in the best use of taxpayers’ dollars, deliver the most service and provide that increased service in the most timely manner. 

We are hopeful that, together, we can find a solution that meets all three of these criteria. Thank you for all your efforts to offer more transit choices to people in Durham. 

Yours truly,

Lindsey E. Park
MPP, Durham
