No, you do not tap off when exiting a Toronto streetcar or bus. The TTC (Toronto Transit Commission) operates on a "flat-fare" system within the city limits. In 2026, you simply tap your PRESTO card, credit card, or mobile wallet once on the reader when you board the streetcar. This single tap grants you a two-hour transfer window, during which you can enter subways or board other buses/streetcars for free without being charged again (as long as you tap each time you enter a new vehicle). If you were to tap off when exiting, the system might mistakenly record a new journey or charge you twice if your two-hour window has expired. The only transit system in the Greater Toronto Area that requires you to "tap off" is the GO Transit (trains and buses) and UP Express, as those fares are distance-based. For the red-and-white TTC streetcars, it's strictly "tap on and you're gone."
