Improvements are coming to Durham College Oshawa GO station 

As part of work to expand GO, we’re making improvements at Durham College Oshawa GO station to support future service growth and provide an enhanced experience for customers. Work will include a new north platform, a reconstructed south platform, two new tracks, three new pedestrian bridges, a new bus loop and changes to the parking lot. The project will also help support future Lakeshore East improvements, including the GO rail extension to Bowmanville.  

Construction will take place in phases, with work expected to continue through the early 2030s.  

Here’s what you need to know 

Phase 1: Preparing the station and temporary bus changes 

• Starting early January 2027, a temporary bus loop will be established in the northeast portion of the main parking lot near Bloor Street West and Thornton Road South.  
• Approximately 230 parking spaces are expected to be unavailable while the temporary bus area is constructed and in use.  
• Two vehicle accesses from Thornton Road South will be unavailable. You can continue to access the parking lot near the pickup and drop-off area and from Bloor Street West. The Bloor Street West access will also be shared with transit buses.  
• Signs and wayfinding will help you move safely through the station and parking lot while these changes are in place. 
• Additional parking: We know it’s not possible for everyone, but if your schedule allows, travelling outside the morning rush may help you find additional parking options at Oshawa GO:   
• Carpool spaces are available to all customers after 9:30 a.m.  
• Reserved parking spaces become available to all customers after 11 a.m. 

• We are actively exploring additional parking options near Whitby GO and will share more information as details are confirmed.

• The temporary bus loop and access changes are expected to remain in place until late 2027.

Phase 2: Building the new bus loop and first pedestrian bridge 

• Starting April 2027, construction will begin on the new permanent bus loop within the existing parking lot. Utility work will also begin around the station building, and some pedestrian routes may change.  
• An additional 480 to 555 parking spaces are expected to be unavailable. 
• In May 2027, construction will begin on the station building addition and pedestrian bridge between the station and the VIA stair tower. The area between the station building and the VIA bridge will be closed and become the new work area for utility work, the building extension, and new pedestrian bridge.  
• The new bus loop will be completed in two stages, first allowing buses to begin using the new area, followed by the remaining finishing work.  
• Some existing customer amenities in the current bus loop, including schedule screens and fare/PRESTO machines, will be removed as construction progresses. Schedule information will be displayed in the temporary bus area.  
• The new bus loop is expected to partially open in early spring 2028.  
• Work on the addition to the station building and new pedestrian bridge will be ongoing until the early 2030s. 

Phase 3: Work near the station building 

• July 2027, track addition construction begins on the south track, and is ongoing until the early 2030s. 
• In the second half of 2027, utility and communications infrastructure work is planned near the station building and existing planter.  
• You may notice temporary changes to pedestrian routes between the parking lot, station building, platform and Tim Hortons.  
• Work will be completed in sections to help maintain pedestrian access, with alternate routes used where required. Signage and staff will help guide you through temporary routes.

Later phases: Platforms, tracks and station connections 

• Later stages of the project include construction of a new north island platform and associated track work.  
• The existing south platform will be demolished and rebuilt, followed by additional track work.  
• Two new pedestrian bridges will be built to connect both platforms.  

What you'll get from these improvements 

Once the project is complete, Durham College Oshawa GO station will have: 

• A newly configured bus loop and parking layout 
• A new north island platform 
• A reconstructed south platform 
• Two new tracks 
• Three new pedestrian bridges connecting the platforms, and  
• Modifications to Durham College Oshawa GO and VIA building, including the reconstruction of the existing pedestrian bridge 
• A new track connection to support the service extension to Bowmanville

We know this is a significant change to your commute. With parking, bus connections and routes through the station changing at different stages of construction, your trip through Durham College Oshawa GO station may look different from what you're used to. We'll keep you informed as work progresses, so you know what to expect before you travel. 

Thank you for your patience as we make these improvements and prepare Durham College Oshawa GO station to better support customers and future GO service.
