# GO Transit fares

GO Transit is the inter-regional transportation authority of the Golden Horseshoe, which includes the Greater Toronto and Hamilton Area. It is Canada's oldest regional transit system, first serving passengers in 1967. (Non-relaible information.

## Fare zones

The service area of GO Transit is divided into a number of fare zones, each of which belonging to a number of fare corridors. Fares on GO Transit are based on the distance between originating and destination fare zones. Tickets between two fare zones are valid for travel between the two fare zones stated on the ticket, as well as between any two fare zones that lie between them on the same fare corridor. Tickets are not generally issued between two fare zones on different corridors, with the following notable exceptions:
* Due to all-day GO train service and the interlining of the Lakeshore West line and the Lakeshore East line, tickets may be issued for trips starting in a fare zone on one line and ending in a fare zone on the other. Similarly, due to the number of GO bus connections between stations on the Lakeshore West line and the Milton line (including Square One Bus Terminal, but excluding Lisgar GO station), tickets may be issued for trips starting in a fare zone in Mississauga or Milton outside of the Lakeshore West line and fare zones on either of the Lakeshore lines.
* Tickets are generally issued for trips between a fare zone inside Toronto and a fare zone outside the City of Toronto, even if they lie in different fare corridors; such tickets are valid between the fare zone outside the City of Toronto to any fare zone inside the City of Toronto for which the ticket value is equal or less. (For example, a ticket from Square One Bus Terminal to Scarborough Centre Bus Terminal would also be valid for trips to Kennedy GO Station, as the trips are of equal value, even though all three locations are on different fare corridors.) Note that Milliken GO Station, despite being physically located within the City of Toronto, is considered to be in a fare zone outside of the City of Toronto for historical reasons.
As all GO Transit tickets are only valid for continuous trips of no more than two and a half hours, multiple tickets may be needed for longer trips.

## Fare classes

GO Transit offers three passenger fare classes: adult, senior and student. Senior fares are available for passengers over the age of 65. As of March 9, 2019, passengers under the age of 12 can ride free on all GO Transit trains and buses.
Student fares are only available for those with acceptable student identification:
* For high school students, school-issued student identification is needed. Note that these do not necessarily need to be identification issued by a school within GO Transit's service area.
* Full-time students of post-secondary institutions anywhere in Canada (not necessarily within GO Transit's service area) for which student identification is reissued each year may use their school-issued student identification for proof of student fare qualification.
* Students at Durham College, University of Ontario Institute of Technology, and Trent University's Oshawa Campus require their school-issued student identification for proof of student fare qualification.
* Students at Centennial College, Humber College, Michener Institute, Mohawk College, Niagara University, Sheridan College, and Trent University's Peterborough campus require a sticker to be affixed to their school-issued student identification for proof of student fare qualification.
* Students at McMaster University holding a Hamilton Street Railway U-Pass require their school-issued student identification for proof of student fare qualification.
* All other post-secondary students require the GO Transit student ID. It is valid for full-time students from October of one year to October of the next year, as long as the student retains full-time status. GO Transit student ID application forms may be obtained from the registrar's office of their institutions. These must be processed at GO Transit's offices at Union Station before they may be used as proof of student fare qualification. Students at Seneca College, Toronto Metropolitan University, York University, University of Waterloo, and the University of Guelph may also obtain GO Transit student identification online, while students at the University of Toronto's St. George, Mississauga, and Scarborough campuses may obtain their GO Transit student identification on campus.

## Fare types

Up until July 31, 2012, GO Transit offered five types of fares:
* Single-ride tickets are for one single journey between two fare zones. These expire four hours after purchase, and are not refundable.
* Two-ride tickets are for two single journeys between two fare zones. These do not expire, but are not refundable.
* Day passes are for unlimited journeys between two fare zones from 3AM one day to 3AM the next. These are not refundable.
* Ten-ride tickets are for 10 single journeys between two fare zones. These do not expire, and unused portions may be refunded 30 days after purchase.
* Monthly passes are for unlimited journeys between two fare zones for one calendar month. They are available for purchase 10 days before the month to 14 days into the month, and must be signed by its user for it to be valid. These may be refundable.
GO Transit stopped selling two-ride and ten-ride tickets on June 1, 2012 and stopped accepting two-ride and ten-ride tickets on July 31, 2012, in favour of using Presto Cards exclusively; paper monthly passes have been discontinued since 1 January 2013; day passes remain available for purchase. Passengers may convert any unused rides on their tickets to equivalent value on a Presto Card before the end of 2012.
There is no distinction between bus and train service.
Fares between two fare zones for a particular type of ticket and passenger category are based on multiples of the standard (adult single-ride) fare as follows:
Fare multiples for ticket users :
| | Adult | Senior | Student |
| Single-Ride | 1 | 0.5 | – |
| Day Pass | 2 | 1 | – |
| Monthly Pass | 34 | 20 | 28 |
Fares are rounded to the nearest $0.05 for single-ride fares and day passes and $1.00 for monthly passes, after fare multiples are applied. The minimum adult single-ride fare (for travel on GO Transit within one fare zone) is always $4.50; other fares depend on the fare zones travelled.

### Presto cards and contactless credit cards

Presto cards and contactless credit cards are accepted on GO Transit. Passengers must tap their cards against the reader upon embarking and disembarking the train or bus. Upon embarking, the minimum fare ($3.70) is always deducted from Presto cards, with fare adjustments performed as the passenger disembarks. With credit cards, charges are processed at the end of the day as a single charge combining all the day's trips.
The following credit cards are accepted: VISA, MasterCard and American Express.
Failure to tap the card upon disembarking ("missed tap-off") will cause the maximum fare to be deducted, under the assumption that the passenger travelled to the point furthest away from the origin point. (For example, passengers failing to tap off when boarding at Union Station will be assessed the fare travelling from Union Station to Kitchener GO Station, the point furthest away on any GO train route serving Union Station.) Passengers regularly travel by GO train may also set a "default trip" between two GO train stations, allowing them to avoid tapping their cards upon disembarking; passengers doing so will have the appropriate fare deducted upon embarking at either endpoint. The default trip is not available on contactless credit cards.
Adult and student passengers using the Presto card receive a further fare discount, depending on the number of trips that have been made per month between two fare zones.
Fare multiples for Presto Card users :
| | Adult | Student | Senior |
| First 30 trips | 0.8885 | 0.816 | 0.4735 |
| Trips 31–35 | 0.8885 | 0.05 | 0.4735 |
| Trips 36–40 | 0.1225 | 0.05 | 0.4735 |
| Each trip thereafter | Free | Free | Free |
If there are rides between different sets of fare zones, the discounts after the 30th trip (students) and 35th trip (adults) will be based on the total value of rides taken so far; the fare discounts are structured so that adult and student passengers pay less over the course of a month compared to paying for a paper monthly pass ahead of time; the discrepancy is to encourage passengers to adopt the Presto card over the paper monthly pass.

### E-tickets

E-tickets can be purchased at tickets.gotransit.com. They must be activated on a smartphone to be valid (they cannot be printed). Single-ride and return tickets cost the same as a paper ticket.

#### Weekend Passes and Weekday Group Passes

Other than single-ride and return tickets, the GO Transit e-ticketing website also offers One-Day Weekend Passes and Weekday Group Passes, which are valid for unlimited travel to any location on the GO Transit network within the validity period of the ticket, regardless of the origin and destination entered when purchasing the ticket. One-Day Weekend Passes are valid for one day on a Saturday, Sunday or statutory holiday for one person. Weekday Group passes are valid for one day from Monday to Friday, excluding statutory holidays, for a group of 2-5 people, depending on the type of pass purchased. These passes are available online only and must be activated on a smartphone to be valid (they cannot be printed). They are not valid on the Union Pearson Express. The prices are as follows:
Weekend Pass and Weekday Group Pass prices :
| Type | Price |
| One-Day Weekend Pass | $10 |
| Weekday Group Pass for 2 | $30 |
| Weekday Group Pass for 3 | $40 |
| Weekday Group Pass for 4 | $50 |
| Weekday Group Pass for 5 | $60 |

### Fare integration

GO Transit offers fare integration services with local transit providers, as well as with Via Rail.

#### Via Rail integration

Via Rail offers interline tickets with GO Transit, where passengers may travel on GO Transit trains and connect with Via Rail trains at any GO station also offering Via Rail services (Aldershot GO Station, Brampton GO Station, Georgetown GO Station, Guelph Central GO Station, Guildwood GO Station, Kitchener GO Station, Niagara Falls railway station (Ontario), Oakville GO Station, Oshawa GO Station, St. Catharines railway station, and Union Station) or vice versa on one ticket; the Via Rail ticket acts as a GO transit proof of payment on the GO transit leg. Via Rail interline tickets are not valid for GO buses when trains are not running.
Via Rail also offered the GO-Via Pak, which allowed holders of GO Transit monthly passes or 10-ride tickets (between applicable fare zones) to ride between Union Station and five GO Stations (Aldershot, Brampton, Georgetown, Oakville, Oshawa) on Via Rail trains which stopped at those stations. The GO-Via Pak was priced at the difference between 10 adult single fares and the equivalent 10 adult economy fares on Via Rail. The GO-Via Pak could not be used with the Presto Card. The GO-VIA Pak was no longer sold after December 15, 2012 and was not accepted as of January 1, 2013.

#### Local transit integration

Fare integration services may exist between GO Transit and local transit providers, where customers may ride GO buses within local service areas using appropriate local proof-of-payment (tickets and/or passes) at no additional cost; GO Transit will also issue a transfer for further travel on local transit providers upon request. Passengers paying by cash or travelling outside the local service area must pay GO transit fares. Passengers using Presto Card will be assessed GO transit fares, although plans are in place for local fares to be assessed instead of GO transit fares whenever they are lower.
* Durham Region Transit – Though in the past, all GO bus routes serving Durham Region were integrated with DRT, since the launch of DRT Pulse only the routes not covered by DRT Pulse are integrated. This includes Route 71, 81, 88, 90, and 91, the latter two only between Newcastle and Downtown Oshawa.
* York Region Transit (YRT) – No routes currently are integrated with YRT, though GO Transit had operated routes both on behalf of YRT and as a complement to YRT service in the past, before its eventual replacement with YRT routes. The last such route to have been integrated was Route 69 Sutton, which was replaced by YRT Route 50 Queensville.

#### GO Transit co-fares

As of February 26, 2024, most local transit systems that connect with GO Transit offer free admission so long as the customer swipes their Presto card on the connecting vehicle. In some cases (where applicable), passengers may also present their GO Transit proof-of-payment (a day pass or single-ride ticket) to the local transit operator.
Passengers using the Presto card or contactless credit card (where accepted) will automatically be assessed the co-fare where appropriate, depending on the status of the local transit operator's integration with the Presto Card or contactless credit card. If the local transit operator does not currently accept the Presto Card or contactless credit card, the co-fare is not applicable with these payment methods.
| Transit agency | Presto card | Co-fare | Notes |
| Barrie Transit | No | Free | Valid to/from Barrie South GO Station or Allandale Waterfront GO Station. Despite Barrie Transit having not adopted the Presto Card on its buses, the co-fare is also accepted for Presto Card holders. |
| Brampton Transit (includes Züm) | Yes | Free | Valid to/from any GO train station in Brampton (Brampton, Bramalea, Mount Pleasant), Lisgar GO Station and Malton GO Station in Mississauga, and Brampton Bus Terminal. Also valid for GO buses connecting to/from Brampton Transit services when using the Presto Card or contactless credit card. Co-fares are only accepted for single-ride and day pass tickets when connecting from GO Transit to BT services. |
| Burlington Transit | Yes | Free | Valid to/from any GO train station in Burlington (Aldershot, Appleby, or Burlington). Also valid for GO buses connecting to/from Burlington Transit services when using the Presto Card or contactless credit card. |
| Durham Region Transit (DRT) | Yes | Free | Valid to/from any GO Station in Durham Region (Ajax, Oshawa, Pickering, or Whitby) or Rouge Hill GO Station in Toronto. Also valid for GO buses connecting to/from DRT services when using the Presto Card or contactless credit card. Co-fares are only accepted for single-ride tickets when connecting from GO Transit to DRT services. A full DRT fare is required when connecting to GO Transit from DRT on a GO Transit single-ride ticket. Due to fare integration, DRT co-fares are not accepted on GO buses, and may not be used to connect between GO trains and GO buses; GO Transit fares will be assessed. |
| Grand River Transit (including iXpress and GRT MobilityPLUS) | No | Free | Valid to/from Kitchener GO Station. Only valid Kitchener GO train service times. |
| Guelph Transit | No | Free | Valid to/from Guelph Central GO Station and University of Guelph. Co-fares are only accepted for single-ride tickets when connecting from GO Transit to Guelph Transit services. A full Guelph Transit fare is required when connected to GO Transit from Guelph Transit on a GO Transit single-ride ticket. |
| Hamilton Street Railway (HSR) | Yes | Free | Co-fares only available using Presto card or contactless credit card. |
| Milton Transit | No | Free | Valid at Lisgar and Milton GO Stations. |
| MiWay (Mississauga Transit) | Yes | Free | Co-fares only offered for Presto card and contactless credit card holders. |
| Oakville Transit | Yes | Free | Valid to/from any GO train station in Oakville (Bronte and Oakville), as well as Clarkson GO Station in Mississauga. Also valid for GO buses connecting to/from Oakville Transit services when using the Presto Card or contactless credit card. |
| Toronto Transit Commission | Yes | Free | From January 7, 2018, until March 31, 2020, Presto card holders who transferred between GO Transit and Toronto Transit Commission (TTC) services were able to save up to $1.50 on their fares as part of a co-fare discount agreement. The discount was not offered for customers who use cash, paper tickets, tokens, or a monthly Metropass on Presto. The program was discontinued on April 1, 2020, after the Ontario government decided not to renew the contract to extend the discounted double fare program, meaning that customers will be charged the full fare when transferring between TTC and GO Transit services within the City of Toronto. On February 26, 2024, free transfers between GO and TTC became available. |
| Region of Peel TransHelp | No | ? | |
| York Region Transit (YRT) (includes Viva and Toronto Transit Commission bus routes serving York Region, north of Steeles Avenue) | Yes | Free | Valid to/from any GO train station in York Region (Aurora, Centennial, East Gwillimbury, King City, Langstaff, Old Elm, Maple, Markham, Mount Joy, Newmarket, Richmond Hill, Rutherford, Stouffville, and Unionville), Milliken and York University GO Stations in Toronto, or Richmond Hill Centre Terminal. Co-fares are only accepted for single-ride tickets when connecting from GO Transit to YRT services or TTC buses in York Region operating north of Steeles Avenue. Riders must use a Presto card or contactless credit card in order to receive their co-fare discount when transferring between Viva bus services and GO Transit since it is not possible to purchase discounted fares or tickets from curbside YRT/Viva single-ride ticket vending machines. A full YRT fare is required when connecting to GO Transit from YRT on a GO Transit single-ride ticket. Enterprise Vivastation is considered part of Unionville GO Station for the purposes of transferring between GO Transit services and Viva Purple and Viva Green. Though TTC routes serving or terminating at Steeles Avenue may briefly enter York Region upon switching from outbound to inbound service, these are not services operated by the TTC on behalf of YRT; and thus co-fares are not offered. There are presently no TTC routes that serve both York Region and serve either of the GO Stations in Toronto where the YRT co-fare is offered. The TTC Times Two program is not valid when connecting to a TTC bus in York Region, even if connecting to a destination in Toronto. |
