Toronto Transit Commission Full Fleet Electrification Study 

To support the Toronto Transit Commission’s (TTC) commitment to convert its entire vehicle fleet to zero emissions, STV delivered a comprehensive suite of services to guide the development of TTC’s full fleet electrification plan. The transition plan provides a strategic roadmap for transforming bus operations, facility infrastructure, maintenance, training and procurement processes to enable long‑term adoption of clean‑energy technologies. STV deployed its proprietary Performance and Evaluation of Electric Bus Routes (PEER) simulation tool to analyze systemwide operational energy needs and assess charging and infrastructure requirements for TTC’s extensive bus network.

What challenges did STV address?

TTC required a holistic understanding of how zero‑emission technologies – battery‑electric, fuel‑cell electric and on‑route charging – would influence daily operations across one of North America’s largest and most complex transit systems. Unique complications included electrifying a diverse fleet of 250 Wheel‑Trans paratransit vehicles and 800 non‑revenue vehicles that do not follow fixed routes, requiring alternative data‑driven modeling approaches.

What solutions did STV deliver?

STV applied its PEER simulation tool to evaluate route‑level energy demands and charging strategies for the existing bus fleet. The team conducted market analysis, developed procurement schedules, outlined facility upgrades, assessed maintenance impacts and prepared workforce development strategies. For non‑fixed‑route vehicles, STV analyzed telematics, real‑time location data and historical operating patterns to guide strategic replacement planning. Funding and financing options were also developed to support TTC’s long‑term transition.

How does this project benefit the region?

The electrification plan supports cleaner air, quieter streets and improved environmental outcomes for Toronto communities. By providing TTC with a practical, data‑driven roadmap, STV is helping accelerate the region’s transition to a more sustainable transportation network and enhancing service reliability for riders.
