Converting FareSavers to Stored Value
If you have leftover FareSavers, you can keep using them on the bus or convert them to Stored Value on a Compass Card. To convert FareSavers to Stored Value on a Compass Card, visit the Compass Customer Service Centre at Stadium–Chinatown SkyTrain Station.
Please note that FareSavers distributed at no cost as part of a program can only be converted to Compass Tickets.
