Many regular bus routes are divided into branch routes, which deviate slightly from the original route, or which terminate at different points along the route. A route is referred to by its route number and/or name (for example, 189 Stockyards). Routes are named after the street or area it serves. All of the TTC's regular routes, except for 99 Arrow Road, 171 Mt. Dennis and 176 Mimico GO, connect to a subway station; 99 Arrow Road and 171 Mt. Dennis serve the areas around their respective bus garages. Vaughan Metropolitan Centre, , and stations do not have any connections to regular daytime TTC bus routes.
