On August 5, 2026, construction firms Webuild and FCC signed a contract worth $4.32 billion to build twin underground tunnels and two new stations in Toronto. The work will link the planned Ontario Line with the Toronto Transit Commission's existing Line 2 subway, creating a direct connection between the two rapid‑transit corridors.

The agreement calls for the creation of two parallel tunnels that will run beneath the city, as well as the construction of two stations where the Ontario Line will intersect with Line 2. The contract represents the first major construction award for the Ontario Line, a high‑capacity transit project intended to expand rapid‑transit service across the city.

Webuild and FCC, both experienced in large‑scale infrastructure, will be responsible for delivering the underground structures and station facilities. The $4.32 billion value reflects the complexity of tunnelling in a dense urban environment and the need to integrate new stations with the existing subway network.

The Ontario Line, still in the planning and design phases, aims to provide a north‑south rapid‑transit spine that complements existing TTC lines. By securing the tunnel and station contract, the project moves from planning toward physical construction, marking a key milestone in the overall schedule.

Toronto officials have highlighted the importance of the connection to Line 2, noting that it will improve network resilience and offer riders additional route options. The contract also signals confidence from the provincial and municipal governments in the project's financing and delivery model.

Construction is expected to begin later this year, with the tunnels and stations slated for completion in line with the broader Ontario Line timeline. The partnership between Webuild and FCC will be closely monitored as the first major construction phase of a transit project that promises to reshape commuting patterns across Toronto.
