What a PRESTO reader actually accepts
PRESTO is the regional fare system behind Toronto's transit network, and a PRESTO reader is a single device that recognises several different things. It reads physical PRESTO cards, digital PRESTO cards in Apple Wallet and Google Wallet, PRESTO Tickets, and ordinary Visa, Mastercard, American Express, Interac Debit and Visa Debit cards, including those cards held in a phone or watch wallet. Because one reader accepts all of them, the TTC advises taking the card you intend to use out of your wallet before tapping, so a card you did not intend to use is not charged.
The same devices are in use across the region. Contactless credit and debit payment works on the TTC, GO Transit, UP Express, Brampton Transit, Burlington Transit, Durham Region Transit, Hamilton Street Railway, MiWay, Oakville Transit and York Region Transit, which is why one card can carry you across several agencies in a day.
Which foreign cards work and which do not
Internationally issued credit cards are explicitly supported, and so are internationally issued Visa Debit and Debit Mastercard cards. The line the TTC draws is on ordinary debit: you cannot use a regular debit card issued by a bank outside Canada. If your card is a domestic debit card from your home country that is not branded Visa Debit or Debit Mastercard, treat it as unusable on a PRESTO reader and plan another payment method.
Two costs are worth knowing before you rely on a foreign card. Your issuer may add currency conversion or out-of-country processing fees to each fare, and each fare counts as a separate transaction against any daily transaction limit on your account. Tapping on and tapping off during a single trip is charged as one transaction, not two.
PRESTO card versus tapping your own card
The prices are close enough that convenience usually decides it. On the TTC an adult pays CAD 3.30 with a PRESTO card and CAD 3.30 with a tapped debit or credit card, against CAD 3.35 in exact-change cash, according to the TTC fares page. Youth pay CAD 2.35 and seniors CAD 2.25, but only on a PRESTO card. A physical PRESTO card costs CAD 4 to buy and has to be loaded with funds in advance; a digital PRESTO card in a phone wallet is free.
Cash is the option to avoid. Cash fares are exact fare only with no change given, they carry no two-hour transfer, and they do not count toward monthly fare capping. A paper transfer taken with a cash fare only covers one continuous one-way trip on TTC vehicles.
The two-hour transfer and the same-card rule
A tap on the TTC buys two hours of travel, not one ride. When you pay with a PRESTO card, a PRESTO Ticket or a debit or credit card, a two-hour transfer is applied automatically from the moment of your first tap, and any TTC bus, streetcar or subway entry within that window is free provided you tap the same card, ticket or device each time. Tap a physical card once and the same card in your phone wallet later and the system may read them as two payment methods, charging a second fare.
Ontario's One Fare programme extends this across agency boundaries. Paying with PRESTO, debit or credit lets you transfer free between the TTC and GO Transit, Brampton Transit, Durham Region Transit, MiWay and York Region Transit, with a two-hour window on the local agencies and three hours from your first tap onto GO Transit. UP Express is not part of One Fare, so a trip from the airport train to the subway is charged as two separate fares.
Monthly fare capping replaced the monthly pass
Monthly fare capping means the TTC stops charging you once you have paid 47 eligible fares in a calendar month, and the rest of that month's TTC trips are free. It applies to fares paid with a PRESTO card, a digital PRESTO card in a wallet, an Interac Debit card or a credit card, and it resets on the first day of each calendar month. Cash fares, PRESTO Tickets and paper transfers do not count toward it.
Most TTC monthly and 12-month passes were discontinued on 31 August 2026 when capping came into effect, with the Adult 12-Month Pass and Post-Secondary Student Monthly Pass the remaining exceptions. For a visitor this is mostly reassurance rather than a saving: reaching 47 fares in a month takes sustained daily commuting, so a short trip will simply pay per ride.
GO Transit charges by distance, so you have to tap off
GO Transit fares depend on how far you travel, which makes tapping off at your destination mandatory rather than optional. If you tap on and never tap off, GO charges you to the last stop on that line or route, because the system has no record of where you left. The tap-off has to use the same physical card, phone or watch you tapped on with.
UP Express works the same distance-based way between Pearson and Union Station, with adult PRESTO fares that fall as low as CAD 4.71 for a single segment against CAD 9.25 for the full airport-to-Union run. Only one-way adult fares are available on UP Express when you tap a bank card; youth, student and senior rates again require a PRESTO card.
One convenience exists only for regular riders: a default trip can be set on a card so a GO Train journey between the same two stations does not need a tap-off. It applies to trains rather than buses, and it is unavailable for a debit card held in a mobile wallet.
When your card is declined at the gate
A refusal at the reader is usually a card-side problem rather than a system fault, and there is a short sequence worth working through before you give up on the card.
- Add the same card to Apple Pay or Google Pay and tap the phone or watch instead, which GO Transit suggests as the first fix for a card that will not read.
- Check with your card issuer whether the card is enabled for transit contactless payments and whether contactless is switched on at all.
- Confirm the card is not a plain foreign debit card, which PRESTO readers do not accept regardless of the wallet you put it in.
- Pay another way for now: cash on a TTC bus or streetcar, a PRESTO Ticket from a fare vending machine, or a physical PRESTO card.
If a tap is accepted at the gate but the charge later fails, PRESTO records an unpaid fare against that card. The card cannot be used to travel again until the unpaid fare is settled, either through the PRESTO app, website or phone system, or by tapping the card on a PRESTO device to clear it, waiting five seconds and tapping again for your new trip. PRESTO also retries the charge automatically for up to 30 days.
Before your first tap
Check three things while you still have signal and time. Confirm with your bank that the card you intend to use is enabled for contactless transit and ask what foreign transaction fees apply per tap. Decide on one card or one wallet and commit to it for the whole trip, since transfers, capping and GO tap-offs all key off that single identity. And keep that card reachable, because it is your proof of payment: a fare inspector will ask you to tap the same card on a handheld device, and producing a different one reads as an unpaid fare.
What this guide does not cover
Fare payment mechanics on the TTC, GO Transit and UP Express are covered here as published on 7 September 2026, and this guide does not cover Wheel-Trans eligibility, the Fair Pass Discount Program, which is for Toronto residents on low incomes, or fares on transit systems outside the PRESTO network. Fares and programme rules change; confirm the current values on the operator's own fares page before you rely on a number here.
