The Guildwood GO Station provides access to GO Train passengers travelling on the Lakeshore East Corridor. It is also a stop for VIA Rail passengers.

The upgraded facility features a new and expanded station building, reconstructed train platforms and surface lots. As part of this project, new installation and upgrades were made to fare systems, utility, storm drainage, LED parking lot lighting, landscaping, and CCTV and PA systems.

Work on the north and south platform included two pre-cast pedestrian tunnels, four elevators, four stairs, snow melting systems, and continuous canopies with integrated heated shelters. Improvements were made to parking lots north and south of the rail corridor and the Kiss & Ride drop-off areas for improved traffic flow.

These upgrades, including provisions for the addition of a fourth track, will support two-way, all-day service for GO Transit patrons on non-shared, dedicated tracks.
