 Presto users who wished to take advantage of the project were required to board at the front door of the vehicle in order to obtain the special paper time-based transfer after tapping their cards on the fare reader there, or else they would have been charged another fare every time they re-tapped on the same route.The pilot program was discontinued on September 3, 2017, the same day the new Flexity Outlook streetcars were deployed on the 512 route, as drivers of the new streetcars are situated inside a fully enclosed cab and are not responsible for handling fare collection or providing paper transfers.The TTC reintroduced a 2-hour time-based transfer on August 26, 2018, but this time system-wide rather than for just the 512 route.
