Public transit refers to shared transportation services available to the general public, including buses, subways, light rail, commuter trains, and ferries. Most Canadian transit systems are operated by municipalities or regional transit authorities, funded through a combination of fares, municipal taxes, and provincial/federal grants. Transit provides mobility for those without cars, reduces traffic congestion, and supports environmental goals by reducing emissions. Major Canadian transit systems include the TTC (Toronto), STM (Montreal), TransLink (Metro Vancouver), and OC Transpo (Ottawa). Smaller communities may offer limited bus service or paratransit for those with disabilities.
