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.

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.
