Vehicles observed now
Current vehicle positions cannot be confirmed. No zero is shown.
Active official notices
The operator notice feed is unavailable or stale, so no all-clear is claimed.
Planned changes
The planned-change register is unavailable. No planned change is confirmed or ruled out.
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.

Reliability evidence by published route cohort
This public route groups more than one official schedule record. Percentiles and observed weekday sets cannot be safely merged from published aggregates, so each matching evidence cohort remains separate.
Observed evidence cohort 53
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.
Evidence window: July 28, 2026 to August 27, 2026
- 77.3%
- Within ±5 min
- 67,577
- Settled arrivals
- 22
- Observed weekdays
- 11.8 min late
- 95th percentile
Patterns by hour (0)
Not enough arrivals yet to split this route by hour.
No repeated pattern below 70% is yet established across at least three service days.
Scheduled bus, but not observed in realtime
Schedule-to-position comparison is not available for this route yet.
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.
Method: last prediction within ten minutes of each arrival; one arrival per trip, stop and service date. Trip coverage: GTFS schedule compared with any GTFS-RT position carrying the same trip and local service date. Sources and limitations.

What is being shown
The current public route group, its published schedule variants and stop patterns, current operations, and matching observed reliability where available.
How it was produced
2 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.
Evidence dates
- Collected or observed
- Computed or assembled
- Sample
- 67,577 settled arrivals across 1 matching reliability records.
- Coverage
- 6 published stop patterns containing 187 stop calls are available on this page.
- Method or data version
- last-prediction-within-ten-minutes-v1; 6a5cf745-35f3-4cac-aa4d-35b6661335fe; 93bdaf6ee5d5ca7fd25a8c81319668a8489f2d9c86433718618d79c61c38bba2

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.
