Better Transit Connections For York Region and Toronto

The Yonge North Subway Extension will transform the commute in York Region, North York and beyond by extending the TTC’s Line 1 service north from Finch Station to Vaughan, Markham and Richmond Hill. The latest plans propose five stations along an extension of roughly 8 kilometres.

When it goes into service after the Ontario Line is complete, the extension will make it faster and easier for more people to travel between York Region and downtown Toronto while cutting down on traffic congestion and pollution.

Metrolinx and Infrastructure Ontario are teaming up with municipal and regional partners to move the Yonge North Subway Extension forward quickly, in the best way possible.

Land acknowledgement

The Yonge North Subway Extension project takes place on the traditional lands of the Mississaugas; including the Mississaugas of the Credit First Nation and Mississaugas of Scugog Island First Nation. These lands are covered by treaties including Treaty 13 and the Gunshot Treaty of 1784 and within the Williams Treaties territory. We acknowledge that Metrolinx operates on these lands and has a responsibility to work with the original keepers of this territory and the many diverse Indigenous Peoples living here today.

Simpler, more connected travel

Not only will extending Line 1 service to Richmond Hill make it easier to travel between York Region and downtown Toronto, it will create convenient connections with local transit services and allow more subway riders to complete their journeys without having to transfer.

The proposed extension will connect to the Richmond Hill GO train and Highway 407 GO bus service, as well as local bus routes at every station.

Transit hubs are proposed at Steeles Avenue and within the Highway 7/Highway 407 corridor (Bridge Station).

More time back in your day

The Yonge North Subway Extension will help you spend less time traveling so that you can dedicate more time to the people and things you care about most.

For example, the extension will reduce the time it takes to travel from the Yonge Street and Langstaff Road area to downtown Toronto by as much as 22 minutes – going from 70 minutes today to 48 minutes with the extension.

As drivers get out from behind the wheel in favour of using the subway, the total distance travelled by cars during morning rush hour will be reduced by 7,700 kilometres.

Better transit, sooner

Running the extension at ground level along the existing CN railway corridor reduces the need for complex, time-consuming, and costly construction of tunnels and underground stations by using a dedicated rail corridor that already exists.

It will ensure the project can be built quickly and reduces the need for large, disruptive excavation sites for underground stations and exit buildings. This allows Metrolinx to limit property needs in the surface-level section of the alignment. Keeping as much work as possible in areas that are more out of the way will also reduce disruptions to utility services like hydro, natural gas, and water service in the surrounding areas.

Metrolinx is committed to addressing any noise and vibration due to construction and operation of the extension to ensure the project improves the quality of life in the neighbourhoods it serves. We will work with communities to ensure a comprehensive array of solutions are in place to address noise or vibration impacts and to ensure designs are sensitive and respectful so that our neighbours can continue to enjoy a high quality of life.
