Starting April 6 the TTC portion of your fare will increase by 10 cents
PRESTO customers who transfer between the TTC and GO Transit or UP Express will get a discount on their fare when they use their PRESTO card.
Save even more with PRESTO when you combine your GO or UP Express trip with TTC; adults can save $1.50, students and seniors can save $0.55.
This discount will be available exclusively to PRESTO customers who pay as they go with their card balance. It is not available to customers who use a PRESTO monthly pass, cash, paper tickets, tokens or a TTC Monthly Pass on a PRESTO card.”
