Aligning the northern part of the Yonge North Subway Extension with the existing railway corridor south of Langstaff Road will create better transit connections, minimize construction impacts, and protect project timelines. It will also ensure the project can accommodate more stations within the approved funding envelope of $5.6 billion.
Running the extension at surface level along the existing railway corridor means the project will better serve the Richmond Hill Centre and Langstaff Gateway urban growth centre, which is poised for significant development. Creating stronger connections here will mean better connections to GO trains and buses and York Region Transit and Viva bus rapid transit services. A major transit hub at Bridge Station will make it easier to travel in all directions, making it convenient for riders to reach destinations across the wider region.
This approach also means we can finish the project quickly by reducing the need for complex and time-consuming construction of tunnels and underground stations. Minimizing the need for large, disruptive excavation sites for underground stations and exit buildings also allows us to limit property needs in the surface-level section of the route. Limiting construction work to areas that are more out of the way will also cut down on disruptions of hydro, natural gas, and water service as we bring you more transit.
The latest plans for the project include five stations.
The Government of Ontario will work with the City of Toronto to explore funding solutions that may come forward for Cummer Station as part of the planning process.
Community input is essential to the work we do.
Metrolinx will reach out to communities through the planning and construction process to create connections between the people we serve and the innovative work being done to bring this important project to life.
If you’d like to connect with us about our plans for the Yonge North Subway Extension, please join us at the virtual and in-person open house events that will be held throughout the course of the project.

We are still determining impacts and confirmation of properties through further environmental assessment and design work.
Metrolinx only acquires properties that are absolutely necessary for projects. Our goal is always to affect the fewest number of people by minimizing the footprint of our land requirements through careful planning and design.
We understand that residents and businesses want specific details about impacts to their properties, and we will reach out individually to property owners as soon as we can.
Community and customer impacts
The bottom of the tunnels – where trains pass over the tracks – will be at least 21 metres below the surface from Yonge Street to approximately where the existing railway corridor meets the southern boundary of Holy Cross Cemetery.
Where the route crosses below Pomona Creek, beyond where homes are located, the tunnels will still be at a depth of 14 metres.
This slightly shallower depth is because the ground level here is slightly lower than the surrounding land in the neighbourhood. From here, it will gradually rise to meet the surface rail corridor just south of Langstaff Road.
Based on what’s been experienced on other recent subway projects in the GTA, we know the sounds and vibrations from subway trains traveling in the tunnels below Royal Orchard will be very difficult to notice.
The 2019 provincial budget estimates capital costs for the Yonge North Subway Extension to be $5.6 billion. Cost estimates for the project will be refined throughout the procurement process.
Metrolinx and Infrastructure Ontario are moving the project forward under the Subway Program, which includes three other rapid transit expansions that will get the region moving — the Ontario Line, the Eglinton Crosstown West Extension, and the Scarborough Subway Extension.
The provincial government has committed almost $17 billion toward the Subway Program, as a whole.
In 2021, the federal government announced a $10.4 billion funding commitment to Ontario’s four priority subway projects, including the Yonge North Subway Extension.
York Region has pledged to contribute proportional funding to the capital construction costs of the project through a preliminary agreement with the provincial government. The final contribution from the region will be subject to further refinements to the project’s budget and scope.
