The Ontario Line - Procurement


Metrolinx is committed to delivering the Ontario Line through a Public-Private Partnership (P3) that is cost-effective, efficient and accountable. P3s are an innovative way of financing and procuring large, public infrastructure projects. P3s make the best use of private sector resources and expertise and transfer project risks to the private sector, which is accountable for providing on-time, on-budget project delivery.

The Ontario Line is being delivered as three separate P3 procurement contracts: one rolling stock, systems, operations and maintenance contract for the nearly 16 kilometre line and two separate civil, stations and tunnel contracts - one for the southern segment and one for the northern segment of the line. The schedules for each contract will be aligned to allow for a single in-service date for the Ontario Line.

On June 2, 2020, Metrolinx and Infrastructure Ontario (IO) issued the first two Requests for Qualifications (RFQ) for the Ontario Line project. This is the first step in selecting the teams who will be responsible for construction. On December 14, 2020 IO and Metrolinx issued the Request for Proposals for the Southern Civil, Stations and Tunnel contract and Rolling Stock, Systems, Operations and Maintenance contract to the RFQ shortlisted teams.

The Northern Civil, Stations and Tunnels Request for Qualification is anticipated to be issued in 2022.

  1. The Rolling Stock, Systems, Operations and Maintenance (RSSOM) package is a 30-year-term contract to design-build-finance-operate-maintain the entire Ontario Line. This contractor will work collaboratively with the TTC and integrate fare equipment with the PRESTO system. The TTC will be responsible for day-to-day operations as they related to customer-facing activities such as fare enforcement and network transit control.
    • Rolling Stock: design, supply, operation and maintenance of the trains
    • Systems: design, build, operation and maintenance of all track, communications and train control systems
    • Operations and Maintenance: design, build, operation and maintenance of the operations, maintenance and storage facility (where the trains are stored); the operations control centre (where staff control train operations and are connected to TTC and GO Transit systems); and the backup operations control centre
  2. The Southern Civil, Stations and Tunnel package is a design-build-finance contract for the southern segment of the Ontario Line, from Exhibition/Ontario Place to the Don Yard portal (west of the Don River).
    • Civil: ground works required 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 to be installed by the RSSOM contractor.
    • Stations: one above-ground station to be integrated with the existing GO Transit Exhibition Station; two underground stations to be integrated with the existing TTC Osgoode and Queen subway stations; four new underground stations (King/Bathurst, Queen/Spadina, Moss Park, Corktown).
    • Tunnel: a six-kilometre tunnel and all associated tunneling work from Exhibition to Don Yard portal (west of Don River).
  3. The Northern Civil, Stations and Tunnel contract scope will be defined in the Requests for Qualification when it is issued. The anticipated 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, there will also be a series of early works projects for bridge, track and other preparatory activities to help advance the delivery of the Ontario Line. Early works will mostly occur along the joint rail corridor where the Ontario Line will operate next to existing GO Transit rail services, including at Exhibition Station.
