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: LAURIER E / COPERNICUS, KING EDWARD / OSGOODE, UOTTAWA A, KING EDWARD / TEMPLETON. 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.

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. Not counted: 3 trips with qualifying later matching vehicle observations. Trips with any notice: 5. 1 partial-capture day not counted.

10 of 564 trips with a usable feed window (1.8%) had no matching position.
These counts may overlap; do not add them. A missing position confirms neither cancellation nor a no-show.

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.
The City’s road work list could not be read right now.
A route counts as near when its timetable path passes within 40 m of the City’s mapped closure; a stop counts when it is within 75 m.

Predictions against the timetable
87.8%
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 6, 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.
24 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
Wide prediction spread 17:00: the 95th percentile is 25.8 min later than the median.
17:00 has 66% of predictions within five minutes of the timetable, against 90% the rest of the day.
Only 96% of scheduled trips were seen; the rest are not counted as missed.

Bottom line
Provider predictions were usually close to schedule, but check the problem times below.
88 in 100 eligible predictions were within 5 minutes of the timetable · 66,401 predictions checkedPrediction sample size: Larger sample

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.

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.

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.

1 hourly block(s) are below 70% across at least three service days: a repeated pattern, not one bad day.
556 / 581 scheduled trips published at least one position across 6 service days (95.7%).
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.
