What happens if you don't tap out of a train station?
What happens if you don't tap out of a train station? Unless you switch to a different train without tapping and the transit fare checker scans your card. Then they'll reprimand you or take down the information on your ID. Apparently not tapping before switching trains messes with their stats and makes them upset because they don't know who to charge.
What happens if I forget to tap off TTC?
If you don't have a default set on your card and you forget to tap off at the end of your trip, you'll be charged the fare to the last stop on the train line or bus route and with your fare type and any applicable loyalty discounts applied.
How many times do you have to tap to tap out?
To perform a tap-out, you tap your co-player's arm or another convenient part of their body twice, and repeat this action as many times and as hard as you need to get their attention. (Typically, once and quite softly is enough).
