context_page_description: The Toronto Transit Commission uses buses and other vehicles for public transportation. The TTC has more than 172 bus routes in operation, and served over 487 million riders each year in 2011. Most bus routes serve the suburban areas of the city, and are tightly integrated with the subway system, with free transfers between the two systems, and most suburban subway stations equipped with bus terminals located within the fare paid area. Several routes run into Downtown Toronto, where buses are less used and the area is instead served by the TTC's streetcar system.
  Many TTC bus routes are divided into branch routes, which deviate slightly from the original route, or which terminate at different points along the route. As well, there are express routes which have limited stops. The system is available 24 hours a day, 7 days a week, but overnight service is limited compared to regular routes. Some bus routes extend beyond the city limits into Mississauga and York Region, as those municipalities contract out bus routes to the TTC outside of Toronto. Despite almost completely being in Mississauga, Pearson International Airport is within the TTC's fare-paid zone.

  The Toronto Transit Commission owned over 2,000 buses in 2010, holding the third largest overall bus fleet in North America, behind the New York City Transit Authority (6,263) and the Los Angeles County Metropolitan Transportation Authority (2,911). Of these, 693 are hybrid electric vehicles, the second largest such fleet in North America. Since 2011, all buses are fully accessible (lift-equipped or low-floor) and equipped with bicycle racks. In 2009, the TTC began its first bus rapid transit service in the city, the York University Busway. The service was replaced after the Line 1 Yonge–University subway extension to Vaughan opened in December 2017, though one route still uses the busway.
