York Region Transit

The bus rapid transit (BRT) division operates the six Viva Rapid Transit bus routes and uses the 196-bus garage near Leslie Street and 16th Avenue in Richmond Hill.[5] In 2015, TOK Transit began a seven-year contract, replacing Veolia Transportation (Transdev) as operator.[4]

The North division includes several bus routes in Newmarket, Aurora, King Township, East Gwillimbury and Georgina. TOK Transit also operates this division and is under contract until April 30, 2021.[4]

The southeast division includes routes in Markham, Richmond Hill, and Stouffville.[6] It is operated by Miller Transit who are under contract until October 2023.[4]

Transdev Canada Inc. is under contract of this division until August 1, 2021.[4]

On July 1, 2017, YRT removed fare zones allowing customers to travel within the region with only one fare.[9] Previously, the YRT/Viva service area was divided into three fare zones. Zone 3 was defined as the portion of York Region north of Ravenshoe Road, and Zones 1 and 2 were divided by Bloomington Road for northbound passengers, just south of King Road for southbound passengers. Passengers crossing a zone boundary had to pay a zone fare supplement in addition to the regular fares.

As with many other transit agencies within the GTA, YRT offers a reduced fare for passengers transferring to YRT or Viva buses from GO Transit under its "Ride to GO" program for those aged 13 and over. Passengers may transfer at a GO train station from a GO Transit route to a YRT bus route or TTC-operated bus routes in York Region (north of Steeles only) and pay the reduced fare with the GO Transit proof of payment. Since Viva is operated on a proof-of-purchase system and single Viva fares are paid or purchased at curbside fare vending machines, riders must use a Presto card when transferring between Viva and GO Transit services in order to access the Ride to GO co-fare discount.

• Though Viva Purple and Viva Green do not directly serve Unionville GO Station, GO Transit co-fares are accepted when boarding either route at Enterprise Vivastation.
• Due to the proximity of Richmond Hill Centre Terminal and Langstaff GO Station, GO Transit co-fares are accepted for transfers between GO services at Langstaff GO station and YRT services at Richmond Hill Centre.

The GO Transit co-fare has been expanded to passengers aged 13 and up with a Presto card who pay their single YRT bus fares on their stored card balance: passengers will automatically be assessed the co-fare (and any YRT or Viva fare supplements, if necessary) when transferring from GO Transit to YRT/Viva regardless of where the passenger boards the YRT bus. Similarly, passengers transferring from YRT/Viva to GO Transit will also be reimbursed the difference between the YRT fare and the co-fare upon disembarking from GO Transit (effectively, the YRT portion of the journey is paid with a co-fare).[10]

Some TTC bus routes travel into York Region and operate on behalf of YRT. This allows passengers to board a TTC bus in York Region and disembark in Toronto and vice versa. Passengers crossing the Toronto–York border at Steeles Avenue on a TTC bus are required to pay separate fares: a YRT fare is required for travel north of Steeles Avenue and a TTC fare for travel south of that street.[11]

Certain YRT routes enter Toronto city limits, but City of Toronto regulations mean that passengers may not board inbound (towards Toronto) YRT routes in Toronto or disembark on outbound (away from Toronto) YRT routes in Toronto.

Since August 26, 2019, riders have been able to use their electronic Presto cards to pay both their YRT and TTC fares on contracted TTC buses operating between York Region and Toronto.[12] While limited-use TTC Presto tickets can be used to pay a TTC fare for the subway (whether in York Region or Toronto) or TTC surface routes in the City of Toronto (south of Steeles Avenue), they cannot be used to pay a YRT fare on any YRT, Viva or contracted TTC bus routes in York Region (north of Steeles Avenue).

On December 17, 2017, the western branch of the Line 1 subway was extended into York Region. Coinciding with that opening, YRT took over the operation of four TTC-operated routes in Vaughan. Unlike the policy with contracted TTC buses north of Steeles, no extra fare is charged when boarding or disembarking at Highway 407 and Vaughan Metropolitan Centre stations in Vaughan, due to the impracticality of a payment-on-exit system.[13] However, a separate fare is required when transferring between YRT bus routes and the TTC subway at these stations, as it is at stations located in or bordering Toronto, such as Finch or Pioneer Village.

An agreement between YRT and Brampton Transit means passengers boarding Züm Queen east of Highway 50 (which largely duplicates service with Viva Orange while in York Region) will be assessed YRT fares even if they intend to disembark in Brampton. As a Brampton Transit route, Brampton Transit fare media (including those loaded onto a Presto card) may be used to board without any additional fares being assessed. However, despite the fare integration, passengers boarding with YRT passes will not be issued transfers for connecting to Brampton Transit routes in Brampton, and passengers boarding with Brampton Transit passes will not be issued transfers for connecting to YRT routes in York Region.

Brampton Transit and YRT have cooperated on routes connecting Brampton and Toronto via York Region, and for a time, certain YRT routes were jointly operated by YRT and Brampton Transit buses, where both agencies' fare media were accepted. The introduction of Züm Queen has ended operation of YRT route 77 to Bramalea City Centre. The acceptance of YRT fares on Brampton Transit routes in York Region are the last vestiges of such cooperation.

  YRT current fleet colours 2007–present

YRT's first fleet (2001–2006) was painted with a white base with blue and gold stripes. During the early years many buses still had their pre-2000 colours from the previous operators with "YRT" painted on the front and sides. The livery was changed On 2007 to a white and several tones of blue. Only the Viva fleet is all-blue, but one Orion I YRT (#2028) was painted all-blue for a colour demo.[14] During the transition to the second colour theme some buses were all white with the old "YRT" label remaining.

In 2006, YRT began installing 150 cameras on YRT (including Viva and Mobility Plus) buses. By the end of 2008, there were to be 210 more cameras added to the system's vehicles.[15] CCTV cameras are also installed in some of the Vivastations in Richmond Hill.
