As of 2026, the minimum amount you can load onto a physical PRESTO card (used for transit in the Greater Toronto and Hamilton Area) varies by the method of payment. If you are loading funds through the PRESTO website or the mobile app, the minimum load has been reduced to just $0.05. This change was implemented to make it easier for riders to top up their cards without needing a significant upfront cost. However, if you are using a Self-Service Ticket Vending Machine at a GO Transit or TTC station, or if you are loading funds in person at a Shoppers Drug Mart or Customer Service Outlet, the minimum load requirement is typically $10. It is also important to note that when you first purchase a physical card, there is a $4 issuance fee for the card itself, in addition to whatever initial balance you choose to load. For the most flexibility in 2026, many riders have switched to using the digital PRESTO card on their smartphone or simply tapping their credit/debit card directly, which avoids the minimum load requirement altogether.
