Infrastructure Ontario (IO) and Metrolinx have released a Request for Qualifications (RFQ), deadline  26/05/2023, for the Advance Tunnel Contract package for the Yonge North Subway Extension. The Yonge North Subway Extension (YNSE) will extend the TTC’s Line 1 subway service approximately 8 km from the existing terminus at Finch Station into the City of Richmond Hill. The project runs through the City of Toronto and York Region, including sections within the City of Markham, the City of Richmond Hill and the City of Vaughan. It will include an approximately 6.3-km tunnelled segment as well as an above-ground segment that will run along the existing rail corridor in the northern section of the route. 

The RFQ outlines the scope of work to design, build and finance the tunnels. This includes the following: 

• Approximately 6.3 km of tunnelling works. 
• Design and construction of launch and extraction shafts, tunnels, as well as headwalls for stations and support of excavation for emergency exit buildings. 
• Construction of CN right-of-way separation barriers to expedite safe corridor access and construction. 

The RFQ is the first step in the procurement process to select teams to deliver the YNSE advance tunnel contract for the project.
