Live route map
Fresh vehicle positions appear on the route below. A marker stops moving when the evidence runs out. We do not invent movement.
The line is the official route. Dots show published stops, buses seen now and stops named in current notices.

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: CAMBRIAN / SEELEY'S BAY, CAMBRIAN / GRAND CANAL, CAMBRIAN / RIVER MIST, CAMBRIAN / REGATTA, CAMBRIAN / KILBIRNIE and 7 more. These are highlighted from route-specific settled arrivals with at least 60 observations over 3 days; the pattern does not prove a cause.
Service date September 19, 2026
The current official GTFS contains no service for this route on this service date.
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 realtime prediction feed is unavailable or stale. Timetable times remain labelled as scheduled only.
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.

Would you count on route 275?
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.

Verdict
Timetable short by 7.4 min in 2 hours of the day.
Runs about 5.9 min early, 15:00, 18:00.
Unreliable 05:00, 16:00 to 18:00: a bad trip runs 32.2 min behind a normal one.
07:00 drops to 34% on time, against 70% the rest of the day.
Scenario: 7 min more running time on 18 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.

Route check
A plain-language summary of the strongest evidence we have. We say when the data cannot answer a question.
Bottom line
We need pickup-point evidence before rating this express route.
Confidence in this summary: High
Based on 4,269 arrivals over 18 weekdays, from Aug 20, 2026 to Sep 19, 2026.
Updated Sep 19, 2026, 1:32 p.m.
These are repeated patterns, not one bad day or an unverified rider report. They are measured the same way as the verdict above, over the same arrivals, but they are counted per stop rather than per hour, so the two 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.
Problem places
We do not yet have enough route-by-stop history to name a recurring problem stop. Rider reports are used as leads, not proof.
Open a time period to see each service day, scheduled trip, feed gap, observed public vehicle ID, and the exact counts behind this summary.
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 18, 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 14, 2026
Operator calendar-date records: 0 added · 3 removed
Feed fingerprint: d6d50360bb16d494 · 151dbfc4-6745-4fbd-9eef-6885ecb708f4

Feed fingerprint: 2f30d876ae731cae · 99de510d-89b0-4652-9d93-217659284cf2
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.
Inbound performance must be checked at pickup points. Early outbound running after pickups are finished is not treated like early service on a regular route.
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: August 20, 2026 to September 19, 2026
52 / 65 scheduled trips published at least one position across 5 service days (80.0%).
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.
Arrival check: the last prediction within ten minutes of arrival, counted once per trip, stop and service date. Trip 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.
The current public route group, its published schedule variants and stop patterns, current operations, and matching observed reliability where available.
1 current GTFS route record variants are grouped by operator and public route number. Stop patterns remain tied to their published variant; aggregated reliability records are not merged into an invented percentile.
