Bus rapid transit In response to escalating congestion on the region's roads, York Region's transit plan included a provision for a bus rapid transit system along the Yonge Street and Highway 7 arterial corridors. This service, known as Viva, was launched in September 2005. Fares Fares for riding YRT can be paid by cash, Presto cards, credit card, the mobile YRT Pay app or Transit pay app. , YRT fares are as follows (the same applies for the YRT's BRT service, Viva): Other fares: Three separate methods of payments are used by transit routes serving York Region: "Pay as you board" on conventional YRT and TTC-operated bus routes heading southbound towards Toronto "Pay as you leave" on TTC bus routes heading northbound into and within York Region (north of Steeles Avenue) "Proof of payment" basis on all Viva routes (customers may board or disembark at any door) York Region's rapid transit bus service, Viva operates on a "pre-paid proof-of-payment (POP)" system, meaning passengers in possession of POP can board these buses at any door. Unlike conventional YRT buses, Viva buses are not equipped with onboard fareboxes, which means passengers are required to purchase single-ride tickets from curbside fare vending machines, tap a Presto card on the fare readers located beside the fare vending machines, or activate their mobile ticket or pass at the platforms prior to boarding. A single-ride ticket has the date and expiry time printed on it at the time of purchase and so it does not need to be validated. Paper POP tickets and transfers are not issued to Presto card holders or YRT Pay app users since both Presto and the app act as POP. Time-based fares and transfers allow for unlimited travel within York Region
