Markers move between GPS fixes using measured progress along the published route. They pause after one measured reporting interval, on a measured standstill, or when evidence becomes stale.
Repeated problem stops: EAGLESON / HAZELDEAN. These are highlighted from route-specific provider predictions compared with the timetable, with at least 60 eligible predictions over 3 days. They do not establish actual arrivals or a cause.
The line is the official route. Dots show published stops, buses seen now and stops named in current notices.
Buses we can see right now appear on the route below. A marker stops when we stop hearing from that bus. We never make up movement.
Service date October 8, 2026
Span and median gap are computed from today’s official GTFS stop_times. They are timetable measures, not observed headways or a frequency guarantee.
These are trip starts. For the time at your stop, open that stop’s departure board.
No upcoming trip start is published in the next four hours.
The current healthy operator position feed contains no vehicle matched to this route.
No matching active notice appears in the current healthy operator feed.
No safely matched planned change is recorded for this route.
These are Otranspo register records, separate from operator alerts. A record is attached only when its route label identifies one operator; ambiguous OC Transpo/STO number matches are withheld.

No sign-in needed. A vote from a device that is not signed in counts a little less than one from an account, and a person who rates many routes counts a little less on each, so no one voice outweighs the rest.

1 of 16 trips with a usable feed window (6.3%) 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: Oct 8, 2026, 3:13 a.m..
4 scheduled trips were excluded from the position check for feed or identity gaps.
Published position coverage: 15 / 20 (75%). 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: Oct 8, 2026, 1:48 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.
1 partial-capture day not counted.
No counted cancellations on this route in the last four weeks. Notices we could not check would be listed below.
Did not come (no bus seen, no notice), last 7 days: 1 of 16 trips we could check.
Last 28 days, September 10, 2026 to October 7, 2026: 4 days counted.
Too few buses were measured to judge bunching: 0 pairs checked, 30 needed.
How this is measured →Not enough trips yet to measure speed between timepoints (20 trips needed for each segment).
How this is measured →Road work and event road closures the City of Ottawa has published, measured as near this route’s path. Near is not proof that the bus is detoured: check the operator’s own alerts for that.

Predictions against the timetable
No comparable percentage published
This service purpose needs a different method. A general percentage could give a misleading picture.
These are provider predictions, not independently measured arrivals. Missing evidence is not counted as on-time service.
Calculated: Oct 8, 2026
1 partial-capture day not counted.
Explore the dated evidence Source of this resultThe 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.
Verdict
Median provider predictions are 5.3 to 8.5 min later than the timetable in 4 hours of the day.
Scenario: 5 to 9 min more running time on 44 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.
| What | When | Measured | Scenario or next investigation |
|---|---|---|---|
| ProblemPredictions later than timetable | 07:00 to 09:00 · 15:00 to 17:00 | 5.3 min late · 8.5 min late | More running time |
Route check
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 7,495 eligible provider predictions over 20 measured days, from Sep 8, 2026 to Oct 6, 2026.
Updated Oct 8, 2026, 2:32 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.
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.

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 September 25, 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.
Service date checked: September 21, 2026
Operator calendar-date records: 0 added · 2 removed
Feed fingerprint: 2f30d876ae731cae · 99de510d-89b0-4652-9d93-217659284cf2

Feed fingerprint: f3f08b9bf8699356 · edd82b80-107c-4eac-9121-2bff2579fdf8
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.
Ordinary on-time scoring does not fit this route’s service purpose. The schedule counts remain visible, but the result waits for the purpose-specific evidence described below.
Checksums let anyone verify which retained timetable produced the counts. A changed count does not identify a cause, cancellation, operator decision, or passenger impact.
No grade is shown until a purpose-specific completion and pickup measure is available.
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
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: September 8, 2026 to October 6, 2026
15 / 16 scheduled trips published at least one position across 4 service days (93.8%).
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.
