Infrastructure Ontario, Metrolinx Shortlist Teams for Two of Three Ontario Line Contracts

Infrastructure Ontario (IO) and Metrolinx have issued two requests for proposals (RFPs) for Ontario Line subway project procurement packages. The two provincial agencies have shortlisted teams and have invited them to bid on two contracts:

  • the Ontario Line rolling stock, systems, operations and maintenance (RSSOM) package; and

  • the Ontario Line southern civil, stations and tunnel (South) package.

The future rapid transit line is one of several plans that the Province of Ontario announced in April, 2019. It stretches 16 kilometres between the Science Centre Station on the Crosstown LRT line and Exhibition Place. It includes elevated, surface, and underground segments, including a portion which shares the GO Transit tracks through east-end Toronto.

IO and Metrolinx issued a request for qualifications (RFQ) to prospective proponents for the RSSOM and South procurement packages in June. They now have evaluated the RFQ submissions and invited the teams that possess the relevant experience and capacity to deliver each project, to submit proposals. The proposals must detail how they will deliver these projects. After evaluating the proposals received, IO and Metrolinx expect to award these contracts in 2022.

IO and Metrolinx say, “A fairness monitor will oversee the entire procurement process.”

According to an IO news release, “The Ontario Line is being delivered as three separate public-private partnership (P3) procurement contracts:”

  • Contract one: rolling stock, systems, operations and maintenance contract for the entire 15.5-kilometre line;

  • Contract two: civil [engineering], stations and tunnels for the southern segment of the line; and

  • Contract three: civil [engineering], stations and tunnels for the northern segment of the line.

Metrolinx will align the schedules for each contract “to allow for a single in-service date for the Ontario Line”.

In the release, IO claims that “creating three separate contracts of manageable size and acceptable risk will encourage competition and active participation from the market to support innovation and ensure that the right teams are in place to successfully deliver the line at the best value for taxpayers.”

The first two contracts include:


  • A design – build – finance – operate – maintain contract for the entire Ontario Line for a 30-year term.

  • Rolling stock: design, supply, operate and maintain the vehicles (trains);

  • Systems: design, build, operate and maintain all track, communications (for example: network, Wi-Fi, close-circuit television [CCTV], passenger information) and train-control systems for the Ontario Line;

  • Design, build, operate and maintain an operations, maintenance and storage facility, an operations control centre and the back-up operations control centre.

The successful proponent would

  • work collaboratively with the TTC in accordance with future operations and maintenance agreements; and
  • integrate fare equipment with the PRESTO fare-card system


  • A design – build – finance contract for the southern portion of the Ontario Line, from Exhibition Place / Ontario Place to the Don Yard portal (west of the Don River).

  • Civil: ground works to build the tunnels and stations; utility and conduit works to prepare for the RSSOM mechanical and electrical systems; guideway structures and facilities to prepare for the track structure that the RSSOM contractor will install.

  • Stations:

  • an above-ground station integrating with GO Transit’s Exhibition GO Station;
  • two underground stations integrating with the TTC’s Osgoode and Queen subway stations; and

  • four new underground stations (King / Bathurst, Queen / Spadina, Moss Park, Corktown).

  • Tunnel: a six-kilometre tunnel and all associated tunnelling works from Exhibition to the Don Yard portal (west of Don River).

IO and Metrolinx expect to issue the RFQ for the northern civil, stations and tunnel contract — the north portion of the line between Science Centre and Gerrard stations — in early 2022. The general scope includes seven stations, a three-kilometre tunnel, two portals and the associated approach structures, bridges and elevated guideways.

In addition to the three main P3 contracts, a series of early-works projects for bridge, track and other preparatory activities will help advance the delivery of the Ontario Line. Early works will occur along the joint rail corridor where the Ontario Line will operate beside GO trains. IO says, “These contracts will be procured traditionally and will begin to be issued to the market later this year.”
