The Ontario government has broken ground on GO Transit’s Bowmanville Extension, marking another milestone in the province’s plan to protect Ontario by relieving gridlock and expanding access to affordable and reliable transit. The project will extend the Lakeshore East GO line 18.7 kilometres into Durham Region, accommodating 17,000 daily trips and 4.9 million boardings annually by 2041. Once complete, the Bowmanville Extension will deliver two-way, all-day service, saving commuters time and money, while bringing families closer to housing and putting 10,400 jobs within walking distance of transit.

“Under the leadership of Premier Ford, our government is making historic investments to bring rapid transit to new communities and drive economic growth across the Greater Toronto and Hamilton Area,” said Prabmeet Sarkaria, Minister of Transportation. “The Bowmanville Extension will transform travel across Durham Region, bringing fast, reliable and affordable GO train service to residents from Oshawa to Bowmanville and connecting thousands of Ontarians to housing and good-paying jobs.”

The first phase of construction includes rebuilding and modifying bridges along the corridor, relocating utilities and making improvements at the Durham College Oshawa GO Station and the adjacent VIA Rail building. Early works began in spring 2025 and included tree clearing, geotechnical investigations along the corridor and the installation of a new watermain in Oshawa.

The Bowmanville Extension will run from Durham College Oshawa GO Station to Bowmanville GO Station, offering service every half hour during peak periods, hourly during off-peak periods and every two hours on weekends.

"At a time of economic uncertainty, our government is investing in critical transit infrastructure that will help make Durham Region an even better place to live, work, and do business. Extending the Lakeshore East line to new stations in Oshawa, Courtice, and Bowmanville is a transformative project that will shorten commute times and strengthen our connections with Toronto and across the region through reliable, two way, all day rail service."
- Todd McCarthy, MPP for Durham
