In a recent article, I detailed the headway reliability of night buses on several routes. In a comment, a reader asked if I could relate that data to “on time” performance.

There are a few problems with that concept, not least that the TTC’s own standard is so lax. The charts presented here are an attempt to show the degree to which departure times on two routes are scattered (307 Bathurst) or more closely bunched in a more-or-less reliable group (335 Jane).

Depending on reader feedback, I will include these charts, or possibly a modified version of them, in future articles about night services.

Updated June 20, 2025: The charts for 307 Bathurst Night Bus have been modified to show the advertised times of buses to show the degree to which service is “on time” or not.

A separate set of charts has been added to show the evolution of departure times northbound over the route from Front to Steeles.
