Busiest GO station in Ontario outside of Toronto gets major upgrade

Oakville GO Station is undergoing a major expansion aimed at improving accessibility, customer experience, and capacity on what officials say is already GO Transit’s busiest rail corridor.

Located along the Lakeshore West line, the station has seen steady growth since it was first commissioned in 1967 — the same year GO Transit launched. Today, Oakville GO handles more than 10,270 customers per day, making it the busiest station on the Lakeshore West line and the second busiest in the entire GO Transit network, behind only Union Station in downtown Toronto.

That level of ridership is a key driver behind the current upgrades, which are part of Metrolinx’s broader GO Expansion program. With nearly $15 billion already invested, the program is designed to significantly increase service frequency and support long-term population and transit growth across the Greater Golden Horseshoe.

Officials say the Oakville project is central to that effort, given its role as the busiest station outside of Union Station — a designation that underscores its importance as a regional transit hub for commuters travelling between Toronto, Hamilton and surrounding communities.

The expanded station will include a wide range of infrastructure upgrades, including platform rehabilitation and accessibility improvements, new mini-platforms, shelters and canopies, tactile edges and digital signage, and a new accessible pedestrian bridge. Four elevators and four staircases will be added to improve access to platforms and the parking structure.

Transit users can also expect a redesigned bus loop with six additional bus platforms, along with new passenger shelters and updated signage. Parking and cycling infrastructure will also be upgraded, including resurfacing work, improved line painting and a new secured bike shelter.

Inside and outside the station building, upgrades are planned for architectural finishes as well as mechanical and electrical systems.

In early April 2026, Metrolinx awarded a contract to the Kenaidan Murphy Joint Venture to carry out the work, following a design development phase that began in December 2024. The project is being delivered under a Construction Manager at Risk model, which brings construction teams into the design process early to help refine materials, methods and scheduling before major work begins. A timeframe of when the project will be finished has not been given.

On-site preparation has already started. In April, crews began setting up a materials laydown area at the northwest end of the station, while a construction compound was established on the south side to support ongoing work. Fencing and trailers are now in place, and signage will guide passengers through any necessary detours.

Once mobilization is complete, crews will construct a temporary crossing for heavy equipment and a widened temporary platform to maintain safe passenger access to trains while construction continues.

Officials say the work is expected to proceed in stages to ensure the station remains operational throughout the project.
