2.Show the back of your PRESTO card to the driver.

Fare payment is required

You must pay your fare using another payment method. In this case, ask the driver for a transfer (your proof of payment in case an inspector asks to see it). If you think the red light could be due to a technical problem, please go to one of our service points.

If you are paying as you go with your PRESTO card (e-wallet), it is not possible to start your trip on an STO bus. However, you can use the PRESTO to transfer to an STO bus from an OC Transpo bus during the validity period of the transfer.
