ACCIONA shortlisted for another Canadian Tunnelling project


Infrastructure Ontario (IO) and Metrolinx have shortlisted ACCIONA as one of the teams for the tunnelling  work that will take place on the Scarborough Subway Extension Advanced Tunnel Project. 

ACCIONA was shortlisted based on the criteria identified  in the Request for Qualifications process that began in March 2020.  Criteria included design and construction experience and the financial capacity to deliver a project of this size and complexity.

The Scarborough Subway Extension is a 7.8 kilometre extension of TTC's Line 2 Bloor-Danforth Subway, from the existing Kennedy Station northeast to McCowan Road/Sheppard Avenue. The line will include three new stations at Lawrence Avenue and McCowan Road, Scarborough Centre and a terminal station at McCowan Road and Sheppard Avenue. Tunnelling is one of the first phases of work for the project. The extension will help to reduce travel times and improve access to jobs, schools and other key destinations to the City.


Project Scope Includes:

  • 7.8 kilometre extension of Line 2 (Bloor-Danforth) subway.
  • The advance tunnel project includes a single-bore tunnel of approximately 10.7 meter internal diameter.
  • Tunnelling work for the length of the alignment.
  • Three new stations: Lawrence Avenue and McCowan Road, Scarborough Centre and a terminal station at McCowan Road and Sheppard Avenue.
  • Emergency Exit Buildings, Traction Power Substations and modifications at Kennedy Station.
  • Transit connections to Line 2, Line 5 - Eglinton Crosstown LRT, GO train service (Stouffville line) and Durham Region Transit bus service.

Project Benefits

  • Improves access to transit for area residents
  • Reduces daily travel times for commuters
  • Economic and community growth along the future transit line and job creation opportunities
  • Reduction in traffic congestion, greenhouse gases and fuel consumption by providing an alternative transportation option
