Welcome

Metrolinx is building the Yonge North Subway Extension to bring TTC Line 1 subway service farther into North York and York Region. The project includes five new stations along an extension of approximately eight kilometres.

As part of this work, there will be a total of six new emergency exit buildings (EEBs) across the entire extension. At this stage, we’re focusing on the three EEBs planned for the portion of the alignment between Clark Avenue and Langstaff Road East.

Between September 10 and September 24, 2025, Metrolinx will host an open house with both virtual and in-person participation options. This will be your chance to learn more about these EEBs, ask questions, and share your feedback.

Virtual open house:

Starting September 10, 2025, you can explore the open house online at any time. You’ll be able to:

• Watch the recorded video presentation
• Review presentation materials
• Submit your questions to our project team

The online question period will close at 5 p.m. on Wednesday, September 24, 2025. Answers will be provided and will be posted to the webpage.
