How do you build a new subway station while keeping one of Toronto's busiest transit hubs moving? 

Join us for a guided tour of Exhibition Station, where regional GO service, local transit, and the future Ontario Line will connect to create one of Toronto's most important transportation hubs. 

Explore the transformation underway as we build a new Ontario Line station and support tunnel construction that will help connect communities across the city. From elevated viewpoints overlooking the site to a close-up look at active construction, you'll discover how today's work is shaping tomorrow's transit network. 

What to expect 

This guided walk will explore: 

• How Exhibition Station is being transformed into a key connection point between GO Transit, TTC streetcar services, and the future Ontario Line. 
• The tunnelling operations underway near Exhibition Station and how crews are building the tunnels that will carry Ontario Line trains beneath the city. 
• Elevated views of the construction site from the pedestrian bridge to gain a unique perspective on the scale and complexity of the work underway. 
• Along the way, our team will share project details, construction updates, and future station renderings to help bring the vision for Exhibition Station to life. 

Before the tour, participants are encouraged to attend the community open house to learn about the latest construction updates.
