Scheduled trips with cancellation notices

—

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

Trips needing investigation

0 of 47 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.

47 with position · 0 to investigate · 13 excluded · 60 scheduled trips

Current feed. No explicit notice for this route in the current feed; this does not guarantee service. Observed: Nov 4, 2026, 1:46 p.m..

Coverage, exclusions and sources

0 of 6 endpoint departures scheduled in the next four hours carried an explicit cancellation at the last check.

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

Published position coverage: 47 / 60 (78.3%). 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, 12:48 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.

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 (4,175 pairs checked at stops).

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

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 3.3 to 4.3 min later than the timetable in 3 hours of the day.

Predictions near the start are about 4 min later than the timetable; the difference grows by another 6.7 min along the route.

16:00 has 49% of predictions within five minutes of the timetable, against 86% the rest of the day.

Scenario: 3 to 4 min more running time on 24 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.

How route 40 has been running

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.

70 in 100 eligible predictions were within 5 minutes of the timetable · 8,637 predictions checked

Prediction sample size: Larger sample

Based on 8,637 eligible provider predictions over 17 measured days, from Oct 6, 2026 to Nov 3, 2026.

Updated Nov 4, 2026, 1:32 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.

16–17: 52 in 100 eligible predictions differed from the timetable by more than 5 minutes (639 predictions over 10 days).
17–18: 45 in 100 eligible predictions differed from the timetable by more than 5 minutes (957 predictions over 9 days).

Possible no-shows after checking feed gaps?: 0 of 47 checked trips need a closer look0 of 47 trips with enough public-feed evidence had no matching position over 7 days. 13 of 60 scheduled trips were excluded because the feed record was incomplete.

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.

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

Within 5 minutes of schedule: 69.6%

2 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

47 / 60 scheduled trips published at least one position across 5 service days (78.3%).

08:001 / 5 trips without a position80.0%
15:002 / 10 trips without a position80.0%
16:001 / 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.
