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: STATION LORRAIN, de l'ARÉNA/LOMBARD. 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.

Span and median gap are computed from today’s official GTFS stop_times. They are timetable measures, not observed headways or a frequency guarantee.

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.

3 of 206 trips with a usable feed window (1.5%) had no matching position.
These counts may overlap; do not add them. A missing position confirms neither cancellation nor a no-show.

Predictions against the timetable
88.6%
of eligible provider predictions were within five minutes of the timetable.
These are provider predictions, not independently measured arrivals. Missing evidence is not counted as on-time service.
Calculated: Oct 9, 2026
2 partial-capture days not counted.
Explore the dated evidence Source of this resultShare of predictions within five minutes of the timetable. Only eligible hours are shown; an absent hour does not mean zero.
20 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.
Verdict
Provider predictions are about 2 min earlier than the timetable, 01:00.
Only 99% of scheduled trips were seen; the rest are not counted as missed.

Bottom line
Provider predictions were usually close to schedule in this dated sample.
89 in 100 eligible predictions were within 5 minutes of the timetable · 71,002 predictions checkedPrediction sample size: Larger sample
Based on 71,002 eligible provider predictions over 28 measured days, from Sep 9, 2026 to Oct 8, 2026.

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 repeated prediction-difference period has cleared the evidence threshold yet.
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 October 7, 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 32,991 arrivals over 13 days; after has 2,710 arrivals over 1 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.

No repeated pattern below 70% is yet established across at least three service days.
176 / 177 scheduled trips published at least one position across 5 service days (99.4%).
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.
