Scheduled service and available evidence

Did the scheduled service run?

Evidence period: Oct 28, 2026 – Nov 3, 2026

Scheduled trips with cancellation notices

Trips in the published timetable marked cancelled without qualifying later matching vehicle observations in our archive. This does not prove the trip did not operate. Not counted: 1 trips with qualifying later matching vehicle observations. Trips with any notice: 1.

Trips needing investigation

0 of 70 trips with a usable feed window (0%) had no matching position.

These counts may overlap; do not add them. A missing position confirms neither cancellation nor a no-show.

70 with position · 0 to investigate · 0 excluded · 70 scheduled trips

Current feed. No explicit notice for this route in the current feed; this does not guarantee service. Observed: Nov 4, 2026, 10:24 p.m..

Coverage, exclusions and sources

0 scheduled trips were excluded from the position check for feed or identity gaps.

Published position coverage: 70 / 70 (100%). This is not a delivered-service rate. 7 service days in this source.

Timetables retained before the service day: 7 / 7 requested days · 0 missing days.

Historical calculation: Nov 4, 2026, 9:10 p.m.

Method: explicit provider notices, archived trip windows and retained timetables. Predictions and positions alone do not prove that a bus ran or was missed.

This service purpose needs a different method. A general percentage could give a misleading picture.

Predictions in the source: 6,399
Weekdays with evidence: 18
Evidence window: Oct 6, 2026 – Nov 3, 2026

These are provider predictions, not independently measured arrivals. Missing evidence is not counted as on-time service.

What about time of day?

Buses arriving bunched

Last 28 days, October 7, 2026 to November 3, 2026: 26 days counted.

2 days left out because the live feed was only partly recorded or its trip numbers did not match the timetable: October 8, 2026, October 15, 2026.

Values and interpretation

1% of back-to-back buses on this route arrived bunched together: 20 of 2,881 pairs checked at stops in the last 28 days. When buses bunch, the wait after them is usually longer.

0% of pairs (10) had a long gap: more than 1.75 times the planned wait between them.

Buses arriving bunched
Time of day	Pairs checked	Bunched	Long gap
Morning rush (6 to 9 a.m.)	1,513	0% (0)	1% (10)
Afternoon rush (3 to 6 p.m.)	1,093	2% (20)	0% (0)

Verdict

What this route needs

Median provider predictions are 6.2 min later than the timetable in 1 hours of the day.

Predictions near the start are about 7.4 min later than the timetable, with a similar difference near the end. This does not establish the cause.

Provider predictions are about 2.4 min earlier than the timetable, 09:00, 15:00 to 19:00.

Wide prediction spread 09:00: the 95th percentile is 23.7 min later than the median.

07:00 has 42% of predictions within five minutes of the timetable, against 70% the rest of the day.

Matched public positions cover 100% of scheduled trips. This is a lower bound on operated service, not an audited delivery result.

Next investigation: test terminal recovery and the preceding trip against operational records. Predictions alone do not establish the cause.

Route check

How route 275 has been running

A short summary of what we know. We say so when we cannot answer a question.

Bottom line

We need to know where this express route picks people up before we can rate it.

Prediction sample size: Larger sample

Based on 6,399 eligible provider predictions over 18 measured days, from Oct 6, 2026 to Nov 3, 2026.

Updated Nov 4, 2026, 9:32 p.m.

Where and when did predictions differ repeatedly?

These are repeated prediction-to-timetable differences, not independently measured service failures. They use the same eligible predictions as the result above, but group by stop rather than hour, so the lists need not match line for line.

Problem times are not ranked because this service needs a purpose-specific test.

No current official notice matches this route.

Prediction differences by stop

We do not yet have enough route-by-stop history to name a recurring problem stop. Rider reports are used as leads, not proof.

Check every trip and date

Open a time period to see each service day, scheduled trip, feed gap, observed public vehicle ID, and the exact counts behind this summary.

What riders want to know

Is any trip cancelled right now?: No live cancellation answerOC Transpo’s live trip-update feed did not answer this check. That is a feed gap. It does not mean zero cancellations, and it is not proof of a cancellation. Open the evidence to see the schedule, retained explicit cancellation notices, and every labelled data gap.
Possible no-shows after checking feed gaps?: 0 of 70 checked trips need a closer look0 of 70 trips with enough public-feed evidence had no matching position over 7 days. 0 of 70 scheduled trips were excluded because the feed record was incomplete. These are cases to investigate, not confirmed no-shows.
How did provider predictions differ from the timetable?: Not enough evidence yet
What wait did provider predictions imply?: No route-level result meets the evidence threshold yet. This does not mean gaps did not happen.

Schedule change check

Published schedule: before and after

This compares the current retained official schedule with the prior retained version. Schedule changes are facts about what was planned; they do not prove that a trip ran.

Current published schedule began October 30, 2026

Selected service day from each published schedule

We check the first Monday after the new schedule began and the Monday one week earlier. Every figure comes from the retained official GTFS versions named below.

At least one selected date uses added or removed calendar-date service. Treat this as holiday or special-service context, not ordinary weekday growth.

Did service improve after the change?

We will compare settled arrivals for the 14 days before and after the change. We publish the comparison only after both sides have at least 7 service days and 200 arrivals.

Ordinary on-time scoring does not fit this route’s service purpose. The schedule counts remain visible, but the result waits for the purpose-specific evidence described below.

Checksums let anyone verify which retained timetable produced the counts. A changed count does not identify a cause, cancellation, operator decision, or passenger impact.

How this route is judged: Express / commuter route

Inbound performance must be checked at pickup points. Early outbound running after pickups are finished is not treated like early service on a regular route.

What this data cannot prove

The public feed does not provide dependable passenger counts or passed-up-rider events. A missing position does not by itself prove a cancellation, no-show, short turn or cause.

See the definitions, thresholds and evidence order

Official current feed: explicit cancellations, skipped stops and active notices.
Matched observations: vehicle positions and settled predictions tied to the official schedule.
Official timetable: what was planned, kept separate from what was observed.
Rider and operator reports: leads about routes, times and places to investigate, not numeric proof by themselves.

Provisional results, published evidence

Data behind this result

An ordinary on-time grade is not appropriate for this service without checking its purpose. The route check above explains the pickup, community-service or event evidence needed. You can still inspect the recorded trips and data gaps below.

Evidence window: October 6, 2026 to November 3, 2026

Eligible predictions checked: 6,399
Weekdays with data: 18

Scheduled bus, but not observed in realtime

70 / 70 scheduled trips published at least one position across 5 service days (100.0%).

05:000 / 10 trips without a position100.0%
06:000 / 15 trips without a position100.0%
07:000 / 5 trips without a position100.0%
08:000 / 5 trips without a position100.0%
14:000 / 5 trips without a position100.0%
15:000 / 10 trips without a position100.0%

This is not a confirmed no-show. A missing position can mean a cancelled or missed bus, but it can also mean an unassigned trip ID or an operator-feed gap. Otranspo publishes the gap because it matters to riders while keeping the conclusion honest.

Prediction check: the last eligible provider prediction no earlier than ten minutes before the scheduled arrival, counted once per trip, stop and scheduled Toronto calendar date. It is compared with the timetable, not an independently measured arrival. Trip-position check: the timetable kept before each service day, matched to recorded positions. Exact IDs are preferred; an OC timetable suffix is matched only to one trip on the same route and date with an overlapping time window. Missing timetables, ambiguous matches and feed gaps stay labelled; they are not confirmed no-shows. Sources and limitations.
