subway arrives at union

Yonge North Subway Extension

Extending Line 1 subway service nearly 8 km north from Finch Station to Richmond Hill.

Early upgrades at Finch Station

Work is underway on early upgrades to get Finch Station ready for major construction on the Yonge North Subway Extension. These ‘early works’ will connect the approximately eight-kilometre subway extension to existing TTC Line 1 service.

Much of the work will happen along Hendon Avenue as upgrades are made to the electrical infrastructure that will bring power to the new subway extension.

A map of traffic changes in the area around Finch Station and details about what to expect during construction can be found in the community notice issued by Metrolinx.

Metrolinx will collaborate closely with the City of Toronto and the TTC to keep customers and road users up-to-date on the work taking place and to keep people moving.

Street-level work

Heavy-duty cables that will travel from an existing traction power substation – a building where electricity is converted to a form suitable for providing power to the subway – on Hendon Avenue to Finch Station, will be secured inside a protective casing and installed underground.

A new fire department connection will also be installed near the intersection of Yonge Street and Hendon.

Tail tracks

The 'tail tracks' that support existing Line 1 service provide temporary parking space for subway trains while they’re not taking riders to and from their destinations. The changes Metrolinx is making to the tail track area involve extending the waterless sprinkler system from the existing service tracks through the tail tracks, along with new cables and other equipment that will link the future subway extension into the existing communications and support systems.

Electrical rooms

Minor renovations will be made to these areas to accommodate the additional power cables that will travel underground from the traction power substation.
