0 of 40 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.

Current feed. No explicit notice for this route in the current feed; this does not guarantee service. Observed: Nov 5, 2026, 1:56 a.m..
10 scheduled trips were excluded from the position check for feed or identity gaps.
Published position coverage: 40 / 50 (80%). 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 5, 2026, 1:08 a.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.
Predictions against the timetable
61.2%
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 5, 2026
6 partial-capture days not counted.
8 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 8, 2026 to November 4, 2026: 20 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 12, 2026.
No bunched buses were measured on this route in the last 28 days (2,087 pairs checked at stops).
0% of pairs (0) had a long gap: more than 1.75 times the planned wait between them.

Verdict
Median provider predictions are 4.2 to 4.4 min later than the timetable in 4 hours of the day.
Predictions near the start are about 6.8 min later than the timetable; the difference grows by another 6.9 min along the route.
Provider predictions are about 1.4 min earlier than the timetable, 09:00.
17:00 has 45% of predictions within five minutes of the timetable, against 74% the rest of the day.
Scenario: 4 min more running time on 20 trips. The schedule-block model adds no buses; fleet and workforce feasibility are unverified.
Assumptions: published departure times, trip blocks and service pattern stay fixed while running time changes. A scheduler must test headways, transfers, recovery, fleet circulation, operator shifts, labour rules and cost before use.

Route check
A short summary of what we know. We say so when we cannot answer a question.
Bottom line
Provider predictions were often far from the timetable in this dated sample.
61 in 100 eligible predictions were within 5 minutes of the timetable · 6,255 predictions checkedPrediction sample size: Larger sample
Based on 6,255 eligible provider predictions over 17 measured days, from Oct 6, 2026 to Nov 3, 2026.
Updated Nov 5, 2026, 1:32 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.
No current official notice matches this route.

Schedule change check
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 November 3, 2026
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.

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.
Still collecting: before has 3,218 arrivals over 10 days; after has 506 arrivals over 2 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.

4 hourly block(s) are below 70% across at least three service days: a repeated pattern, not one bad day.
40 / 50 scheduled trips published at least one position across 5 service days (80.0%).
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.
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 4, 2026 · 10 trips in the retained timetable · retained notices; capture coverage unverified
In short: 9 with a matched position · 0 with no matching position (to investigate) · 1 with an unknown outcome.
