Project Overview
Through a joint venture, Ferrovial Construction and VINCI Construction Grands Projets, are delivering the Ontario Line Southern Civil, Stations and Tunnel work for Metrolinx and Infrastructure Ontario as part of a design-build-finance contract. The Ontario Line South project is part of Toronto’s transformative new 15.6-kilometre rapid transit line connecting Exhibition Place to the Eglinton Crosstown LRT at Don Mills Road. The Ontario Line south section includes civil works, six kilometers of tunnel and seven new or integrated stations designed to ease congestion, improve commute times, and boost urban mobility. With innovative approaches to working in urban environments and heritage preservation integrated in design, the Ontario Line project is helping to deliver a new subway through the heart of downtown Toronto.
Benefiting the Community
The Ontario Line will provide faster, more frequent and reliable rapid transit, allowing over 227,500 people to live within a 10‑minute walk of a station. It will reduce daily commute times, relieve crowding on Line 1, and give Toronto residents access to up to 57,000 additional jobs within 45 minutes. The line is expected to reduce traffic congestion by eliminating approximately 28,000 car trips per day, lower greenhouse gas emissions, and support economic growth and job creation along the corridor, with an estimated 388,000 daily trips once completed.
Project Scope
The scope of the Ontario Line South Civil design-build-finance package includes:
- Tunnelling: Six-kilometers tunnel from Exhibition to Don Yard Portal.
- Stations: Seven total – including one above-ground (Exhibition), two underground integrated with TTC subway (Osgoode and Queen), and four new underground stations (King/Bathurst, Queen/Spadina, Moss Park, Corktown).
- Civil: Groundworks required to build the tunnels and stations; utility and conduit works to prepare for the Rolling Stock, Systems, Operations and Maintenance (RSSOM) mechanical and electrical systems; guideway structures and facilities to prepare for the track structure to be installed by the RSSOM contractor.
Designed to Innovate
The Ontario Line South project is unique due to its integration with existing transit systems, advanced tunnelling methods, and construction in highly constrained urban environments:
- Integration with two major transit systems (GO Transit and TTC subway).
- Use of advanced tunnelling technologies including TBMs and roadheaders to complete excavation in challenging downtown environments.
- Civil construction across densely populated urban areas with significant heritage and utility constraints.
