Transit insights
Fleet status
See published fleet inventory, reliability and current vehicle observations with their source limits.
A dated fleet inventory and maintenance report sit beside current public vehicle observations. They answer different questions.
Fleet composition, not the number available for today’s service.
OC Transpo Transit Committee update · slide 22 ↗Current vehicle observations, not fleet availability or repair status. Latest feed observation: Oct 3, 2026, 3:33 a.m.
Open observed vehicles ↗Retained public GTFS-RT positions
What did public vehicle feeds show?
Look back at retained position samples for one service date. These are feed observations, not a count of physical buses or completed trips.
Retained position evidence is temporarily unavailable.
Which feed IDs were seen?
One selected service date and operator. These public identifiers are observed in retained positions; they are not a physical vehicle roster.
The observed ID list is temporarily unavailable.
Method: retained public position feed IDs grouped by Toronto service date (04:00–03:59). The peak is the largest sampled minute, not an in-service or fleet peak. Feed IDs can change or be reused. The expected polling schedule is unavailable. A minute without retained positions could be an empty feed, a failed request, or a collection gap.

Search the live public-feed records by route or feed ID. Feed IDs have not been verified against physical fleet numbers.
Open observed vehicles ↗The September 2027 figures are projections, not observed inventory. The update does not publish a current in-service or repair count on these slides.
Official feeds, calculated measures, civic data, and rider observations stay visibly separate. Missing evidence is unavailable, never zero.
