Reviewing TTC Surface Delay Data 2025-2026

This article is a followup to a review of subway delay data published here in early June.

Four sets of data are summarized here:

  • Bus data January 2025 through April 2026
  • Streetcar data January 2025 through May 2026
  • Line 6 Finch data December 2025 through May 2026
  • Line 5 Eglinton data February through May 2026

There is no bus data for May 2026 because the TTC’s June 22, 2026 update on the City’s Open Data site did not include it.

The Open Data files include a key translating delay codes to text. However, many codes used in the logs do not appear in the key, and in those cases I have used “?” in the tables. I have asked TTC for an updated code list, but they have not replied.

Among the information shown in these delay logs:

  • “No Operator Available” is a serious problem related to TTC staffing levels.
  • Diversions account for a large number of delays, notably on the bus network, not just streetcars.
  • Collisions involving buses and streetcars are common.
  • Weather related delays including autos blocking tracks peak in winter months for buses and streetcars.
  • Streetcar delays related to switches are reported under various codes, but there is no code for derailment thereby masking the number of the most serious track-related events.
  • The number and length of delays on 6 Finch have fallen by over 50% since the opening months.
  • A common source of delay on 5 Eglinton relates to guideway intrusion.
