Toronto transit infrastructure

Toronto’s transit infrastructure includes an extensive network of subways, streetcars, buses, and commuter trains serving the city and surrounding areas. The Toronto Transit Commission (TTC) operates most local transit, featuring four subway lines that connect key neighborhoods and downtown. Streetcars run along main corridors, providing flexible surface transit. GO Transit connects Toronto to suburban regions via commuter trains and buses, facilitating regional travel. The system is continually evolving through upgrades and expansions to improve capacity and efficiency, aiming to support a growing population and sustainable urban mobility.
