4 of 468 trips with a usable feed window (0.9%) had no matching position.
These counts may overlap; do not add them. A missing position confirms neither cancellation nor a no-show.

Predictions against the timetable
70.6%
of eligible provider predictions were within five minutes of the timetable.
Share of predictions within five minutes of the timetable. Only eligible hours are shown; an absent hour does not mean zero.
These are provider predictions, not independently measured arrivals. Missing evidence is not counted as on-time service.
Calculated: Nov 4, 2026
2 partial-capture days not counted.
20 hourly cohorts meet the thresholds of 30 predictions and 5 service days. Hourly thresholds are assessed separately from the route-wide aggregate.
Improvement or decline requires comparable periods. This single result cannot establish a trend.
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.
1% of back-to-back buses on this route arrived bunched together: 489 of 97,598 pairs checked at stops in the last 28 days. When buses bunch, the wait after them is usually longer.
0% of pairs (402) had a long gap: more than 1.75 times the planned wait between them.

Median provider predictions are 3 to 3.6 min later than the timetable in 6 hours of the day.
Predictions near the start are about 3.5 min later than the timetable, with a similar difference near the end. This does not establish the cause.
Next investigation: test terminal recovery and the preceding trip against operational records. Predictions alone do not establish the cause.

Route check
A short summary of what we know. We say so when we cannot answer a question.
Bottom line
Provider predictions often differed from the timetable; actual arrivals were not independently measured.
71 in 100 eligible predictions were within 5 minutes of the timetable · 146,779 predictions checkedPrediction sample size: Larger sample
Based on 146,779 eligible provider predictions over 27 measured days, from Oct 6, 2026 to Nov 3, 2026.
Updated Nov 4, 2026, 8:32 a.m.
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.

Still collecting: before has 76,487 arrivals over 14 days; after has 27,129 arrivals over 5 days. No improvement or decline is claimed yet.
Checksums let anyone verify which retained timetable produced the counts. A changed count does not identify a cause, cancellation, operator decision, or passenger impact.
We compare the last eligible provider prediction for each scheduled arrival with the official schedule. These are not independently measured arrivals. A result needs at least 200 eligible predictions. Within 5 minutes is the rider-facing target used here.
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.
Provisional results, published evidence
Each hour compares the last eligible provider prediction for a scheduled arrival with the timetable. “Within 5 minutes” describes that prediction difference, not a measured arrival or proof that a bus ran.

8 hourly block(s) are below 70% across at least three service days: a repeated pattern, not one bad day.
464 / 468 scheduled trips published at least one position across 1 service days (99.1%).
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.
Dated service
The timetable, notices and what the live feed says are shown apart. Seeing a bus on the map does not prove you can board it.
November 3, 2026 · 71 trips in the retained timetable · retained notices; capture coverage unverified
