Fares and tickets

You can use the STO's e-wallet on OC Transpo buses, but first you have to validate it on an STO bus, which entitles you to an electronic transfer for up to two hours. You cannot use the STO's e-wallet when starting a trip on OC Transpo. Other fare packages, such as the one-day, three-day and seven-day passes may be suitable for you for occasional trips.

IMPORTANT: If your trip starts on OC Transpo, you must pay your fare at an O-Train station vending machine, pay cash on the bus and ask the driver for a transfer, or use the Presto card mobile wallet.
