Scheduled trips with cancellation notices

—

No retained notice returned; this does not prove zero cancellations.

Trips needing investigation

0 of 35 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.

35 with position · 0 to investigate · 10 excluded · 45 scheduled trips

Current feed. No explicit notice for this route in the current feed; this does not guarantee service. Observed: Nov 4, 2026, 2:42 p.m..

Coverage, exclusions and sources

0 of 5 endpoint departures scheduled in the next four hours carried an explicit cancellation at the last check.

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

Published position coverage: 35 / 45 (77.8%). 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, 1:37 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.

What about time of day?

7 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.

Buses arriving bunched

Last 28 days, October 7, 2026 to November 3, 2026: 21 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.

Values and interpretation

No bunched buses were measured on this route in the last 28 days (2,411 pairs checked at stops).

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

When this route is usually busy

From the load level STO’s buses report, over the last eight weeks. A time is marked usually busy when at least half of the trips with a reading reached standing room or fuller.

Based on 56 computed days.

Source: the occupancy status in STO’s public real-time vehicle feed, which STO sets from each bus’s load sensor (seats available under 60% full, standing room under 90%, full above 90%).
Each trip counts once per time of day, at the highest load it reported.
Reports of an empty bus are left out, because older records could not tell an empty bus from one with no sensor.
A time of day needs at least 12 trips on at least 4 different days before anything is shown. Holidays are counted with their day of the week.

What this route needs

Median provider predictions are 5.9 min later than the timetable in 3 hours of the day.

Predictions near the start are about 8.4 min later than the timetable, with a similar difference near the end. This does not establish the cause.

18:00 has 36% of predictions within five minutes of the timetable, against 61% the rest of the day.

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

Bottom line

Provider predictions were often far from the timetable in this dated sample.

60 in 100 eligible predictions were within 5 minutes of the timetable · 5,008 predictions checked

Prediction sample size: Larger sample

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.

18–19: 65 in 100 eligible predictions differed from the timetable by more than 5 minutes (203 predictions over 7 days).
16–17: 55 in 100 eligible predictions differed from the timetable by more than 5 minutes (619 predictions over 9 days).
17–18: 54 in 100 eligible predictions differed from the timetable by more than 5 minutes (682 predictions over 9 days).
15–16: 40 in 100 eligible predictions differed from the timetable by more than 5 minutes (81 predictions over 7 days).

What riders want to know

Is any trip cancelled right now?: 0 of 5Checks trips starting at route endpoints in the next 4 hours. This is not a historical cancellation rate.
Possible no-shows after checking feed gaps?: 0 of 35 checked trips need a closer look0 of 35 trips with enough public-feed evidence had no matching position over 7 days. 10 of 45 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?: At the 95th percentile, the predicted difference was 15.5 min (positive means later; negative means earlier)60 in 100 eligible provider predictions were within 5 minutes of the timetable; actual arrivals were not measured here.
What wait did provider predictions imply?: No route-level result meets the evidence threshold yet. This does not mean gaps did not happen.

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: Regular all-stop route

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.

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

How did predictions compare with the timetable?

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.

Scheduled bus, but not observed in realtime

35 / 45 scheduled trips published at least one position across 5 service days (77.8%).

16:001 / 10 trips without a position90.0%
17:001 / 10 trips without a position90.0%

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.
