Verdict
What this route needs
Timetable short by 3.3 min in 1 hours of the day.
Fix: 3 min more running time on 5 trips. No extra buses.
This changes running time only. It does not move departure times, rewrite headways, or check that a driver’s shift still fits, and a scheduler has to.

Route check
How route 66 is doing
A plain-language summary of the strongest evidence we have. We say when the data cannot answer a question.
Bottom line
Service is unreliable often enough to affect riders.
70 in 100 arrivals were within 5 minutes of schedule · 2,742 arrivals checkedConfidence in this summary: High
Based on 2,742 arrivals over 18 weekdays, from Aug 9, 2026 to Sep 8, 2026.
Updated Sep 8, 2026, 2:32 a.m.
Where and when does it keep going wrong?
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.
- 5 p.m.–6 p.m.: 61 in 100 arrivals were more than 5 minutes early or late (95 arrivals over 4 days).
- 9 a.m.–10 a.m.: 49 in 100 arrivals were more than 5 minutes early or late (118 arrivals over 3 days).
- 4 p.m.–5 p.m.: 39 in 100 arrivals were more than 5 minutes early or late (78 arrivals over 4 days).
- 2 p.m.–3 p.m.: 32 in 100 arrivals were more than 5 minutes early or late (145 arrivals over 4 days).

What riders want to know
- Is any trip cancelled right now?
- 0 of 3
- Possible no-shows after checking feed gaps?
- 17 of 70 checked trips need a closer look
- How late does this route get?
- The slowest 5 in 100 were more than about 23.7 min late
- Do buses bunch or leave long gaps?
- No route-level result meets the evidence threshold yet. This does not mean gaps did not happen.
Checks trips starting at route endpoints in the next 4 hours. This is not a historical cancellation rate.
17 of 70 trips with enough public-feed evidence had no matching position over 7 days. 6 of 76 scheduled trips were excluded because the feed record was incomplete. These are cases to investigate, not confirmed no-shows.
70 in 100 arrivals were within 5 minutes of schedule.
Schedule change check
Fall schedule: before and after
This compares the official schedule that ended with the one that started August 30. Schedule changes are facts about what was planned; they do not prove that a trip ran.
Current published schedule began September 4, 2026
What the official notice says about this route
The City’s public summary did not name this route. The feed comparison below can still show a changed timetable, but it cannot tell us why it changed.
Read the official August 30 service-change notice →One comparable weekday from each published schedule
We use 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.

Did service improve after the change?
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 1,428 arrivals over 9 days; after has 26 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.
How this route is judged: Regular all-stop route
We compare observed arrivals with the official schedule. A result needs at least 200 arrivals. Within 5 minutes is the rider-facing target used here.
What this data cannot prove
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.
See the definitions, thresholds and evidence order
- Official current feed: explicit cancellations, skipped stops and active notices.
- Matched observations: vehicle positions and settled predictions tied to the official schedule.
- Official timetable: what was planned, kept separate from what was observed.
- Rider and operator reports: leads about routes, times and places to investigate, not numeric proof by themselves.
Would you count on route 66?
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.

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: D.R.D.C., CARLING / GRANDVIEW, CARLING / GRANDVIEW, CARLING / DAVIDSON'S SIDE, CARLING / DAVIDSON'S SIDE and 4 more. These are highlighted from route-specific settled arrivals with at least 60 observations over 3 days; the pattern does not prove a cause.

Provisional results, published evidence
When is this route reliable?
Every hour below is backed by this route’s settled arrivals. “On time” means no more than five minutes early or late, so a bus that leaves very early counts as a failure for the waiting rider.

Scheduled bus, but not observed in realtime
53 / 76 scheduled trips published at least one position across 4 service days (69.7%).
- 14:005 / 8 trips without a position37.5%

- 08:002 / 8 trips without a position75.0%
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.

Limits to keep in mind
- Schedule variants can apply on different dates. A grouped route is not a claim that every pattern operates today.
- Accessibility fields report only what the operator publishes; an unknown value is not confirmation of access.
