The Toronto Transit Commission announced on July 15, 2026 that it will install a new communications‑based train control (CBTC) signalling system built by Hitachi Rail Canada. The upgrade is aimed at allowing more frequent trains and improving overall service reliability across the city’s subway network.
The TTC’s existing signalling infrastructure relies on older technology that limits how closely trains can run together. By switching to the modern CBTC system, the agency expects to increase train frequency, reducing wait times for riders. The partnership with Hitachi Rail Canada formalizes the transition from legacy equipment to a digital, data‑driven control platform.
The decision follows a signed agreement between the TTC and Hitachi Rail Canada, under which the Japanese‑owned firm will supply the automatic train signalling solution. While specific implementation timelines were not disclosed, the move reflects the TTC’s broader effort to modernise its operations and deliver a more dependable transit experience for Toronto commuters.
