At the April 26, 2018 Metrolinx Board Meeting, two of the public agenda items dealt with changes in fares and in the fare collection system:
Presto Mobile is a new smartphone app that is intended to become a single point of access to Metrolinx services including fare payment and trip planning.
On the fare integration front, Metrolinx is contemplating the effects of funding announced in the 2018 provincial budget to subsidize lower fares for short GO Transit trips, and for cross-border fares between Toronto and the 905-area municipalities.
For the sake of discussion, this article assumes that the provisions in the budget will actually be implemented regardless of which party forms the government after the election in June.
Updated May 7, 2018 at 9:50 am: Metrolinx has confirmed that the double discount for GO+TTC fares would still apply to the new $3 fare within Toronto.
