A bus is a large motor vehicle designed to transport multiple passengers along fixed routes, stopping at designated locations to pick up and drop off riders. Buses are the backbone of most Canadian public transit systems, providing flexible service that can be adjusted more easily than rail. Conventional buses operate in mixed traffic, while bus rapid transit (BRT) uses dedicated lanes for faster, more reliable service. Transit agencies operate various bus types including standard 40-foot buses, articulated (bendy) buses for high-demand routes, and smaller community shuttles. Accessible low-floor buses have become standard, allowing wheelchair users and people with mobility devices to board without steps.
