Transfers
Transfers are an integral component of the TTC's fare system. A transfer is a proof of payment issued when a fare is paid; the transfers allows riders to switch between most routes without paying additional fares. Transfers are valid where routes intersect and for one-way trips. On most routes, they are not good for stopovers. Pass holders are not entitled to transfers.
Subway and RT stations may have surface terminals for connecting surface routes. The stations and terminal form a fare-paid zone, and transfers are not required to switch between routes that enter the zone. Where terminals are not present, as is typical in the downtown core, transfers are required to switch between the subway and surface routes.
