A ward boundary, route inventory, destination list, population count or employment count supplies civic context. None of those values alone measures passenger demand, household trip effects, transfers or daily attendance.

Ottawa wards are municipal wards. They are not Gatineau electoral districts, and results from the two boundary systems are not interchangeable.

Verdict

What would fix transit here

Worked out from the routes that serve this ward. Each item names the route, when it happens, and what would change it.

43 of 49 show a repeated lateness pattern consistent with insufficient scheduled running time. A scheduler should test a running-time scenario; labour, fleet, recovery and transfer impacts are not established here.

Worst here: route 7, late by the timetable 08:00 to 23:00, 4.1 min late.

Best here: route 33, observed-position lower bound, 100%.

47 of 49 routes here had something measurable to report.

What we know about train service here

Open the train observation report

Trains are not in the public data feed

OC Transpo publishes live positions for its buses, and this site measures them: millions of bus arrivals every month, which is where every bus figure on this site comes from. The same public feed carries no train positions, so this site has never recorded a single train arrival. Nothing here can tell you where a train is, or whether Lines 1, 2 and 4 run on time.

This is a gap in what is published, not a gap in the trains. If train positions were published the way bus positions already are, riders would get the same record for rail that they have for every bus route on this site.

Recent shared train observations

These are rider sightings approved by a moderator. They show a reported time and place. They are not official train positions, a complete train count, or proof of a cause.

No approved rider observation matches this place or line in the last 31 days. That does not mean no train ran or no problem occurred.

Official timetable

OC Transpo does not publish O-Train positions or arrival predictions in the public feed Otranspo receives. Schedules, official alerts, and rider observations are shown separately so one source cannot impersonate another.

How SOMERSET is doing

Two different failures hide inside one on-time percentage, and they have opposite fixes. These separate them. Each figure is a share of the route-hours this site measured well enough to speak for, and the count it is out of is shown beside it.

Measured over 732 route-hours. 7 more were observed too thinly to count, and are excluded rather than assumed good.

Scheduling

Whether the timetable describes the trip that is actually made. A route late by the same amount every day is not unreliable, it is mis-scheduled, and every operator is driving a schedule nobody can keep.

Who can fix it: A service planner
What it costs: Cost unavailable until fleet, labour, recovery and transfer effects are tested.

Timetable matches the trip

65%

Hours where the middle arrival is within three minutes late and one minute early of the timetable.

Route-hours where the timetable is short

254of 732

Hours where the middle arrival is three minutes late or worse. Each is a candidate for a running-time rewrite.

Route-hours running early

2of 732

Hours where buses typically leave early. Riders who arrive on time can still watch one go.

Running time a short hour needs

3.9min

For a typical short hour, the minutes a planner would add.

Operations

Whether a bad trip is close to a normal one. A route on time on average but wildly variable has a timetable that is right and something else that is not. Padding the schedule here makes every rider’s trip longer while the bad trips stay bad.

Who can fix it: Operations, and often the road itself
What it costs: Cost unavailable until the operational cause and remedy are established.

A bad trip is close to a normal one

98.2%

Hours where the worst trips run less than twenty minutes behind the normal one.

Route-hours that are unpredictable

13of 732

Hours where they run twenty minutes or more behind it. Adding running time does not fix these.

How far behind a bad trip runs

22.8min

For a typical unpredictable hour, how far behind a bad trip runs.

Vehicle visibility to investigate

The current summary uses seven days. For every route, you can also open yesterday, the last 7 days, or the last 30 days and inspect the day, scheduled trip, excluded feed gaps, and every observed public vehicle ID. An absence does not prove a vehicle fault or operator decision.

What is being shown

A ward-level inventory of scheduled transit, public washrooms, drinking-water locations, and observed OC Transpo bus arrivals at stops inside the ward.

How it was produced

Current imported records are assigned by point-in-polygon to the sourced ward boundary. Reliability uses one settled arrival per trip, stop, and service date in the latest 28 completed service days. On time is within ±5 minutes, with publication thresholds of 20 observed weekdays and 500 arrivals.

Imported: August 4, 2026 at 10:43 a.m.
Computed or assembled: September 23, 2026 at 12:17 p.m.
Sample: 237,393 settled arrivals across 21 observed weekdays support the reliability result.
Method or data version: ward-counts-v1 + ward-stop-settled-arrivals-purpose-aware-v3

Limits to keep in mind

Counts describe the published inventory inside the boundary, not service quality or access from every address.
Reliability covers observed OC Transpo bus arrivals at geographically assigned stops. Rail and arrivals without settled evidence are not represented.
An unavailable count remains unavailable. It is not changed to zero.
