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. Trips with any notice: 10.

Trips needing investigation

3 of 18 trips with a usable feed window (16.7%) had no matching position.

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

15 with position · 3 to investigate · 7 excluded · 25 scheduled trips

Current feed. No explicit notice for this route in the current feed; this does not guarantee service. Observed: Nov 4, 2026, 2:57 p.m..

Coverage, exclusions and sources

0 of 3 endpoint departures scheduled in the next four hours carried an explicit cancellation at the last check.

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

Published position coverage: 15 / 25 (60%). 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, 1:38 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.

Predictions against the timetable

No comparable percentage published

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

Predictions in the source: 2,315
Weekdays with evidence: 13
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.

6 partial-capture days not counted.

What about time of day?

The general hourly comparison is not suitable for this service purpose. Source records remain available.

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

8% of back-to-back buses on this route arrived bunched together: 33 of 432 pairs checked at stops in the last 28 days. When buses bunch, the wait after them is usually longer.

58% of pairs (251) had a long gap: more than 1.75 times the planned wait between them.

A cause is shown only when STO’s own alert for that trip gives one.

Did not come (no bus seen, no notice), last 7 days: none of the trips we could check.

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.

Route check

How route 550 has been running

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

Bottom line

We need to confirm how this service is meant to work before rating it.

Prediction sample size: Larger sample

Based on 2,315 eligible provider predictions over 13 measured days, from Oct 6, 2026 to Nov 3, 2026.

Updated Nov 4, 2026, 2:32 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?: 0 of 3Checks trips starting at route endpoints in the next 4 hours. This is not a historical cancellation rate.
Possible no-shows after checking feed gaps?: 3 of 18 checked trips need a closer look3 of 18 trips with enough public-feed evidence had no matching position over 7 days. 7 of 25 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.

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: School route

No grade is shown until a purpose-specific completion and pickup measure is available.

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: 2,315
Weekdays with data: 13

Scheduled bus, but not observed in realtime

15 / 25 scheduled trips published at least one position across 5 service days (60.0%).

06:004 / 10 trips without a position60.0%
15:006 / 15 trips without a position60.0%

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.
