Live commercial truck delays at St. Stephen-Calais (New Brunswick ↔ Maine) · updated every 15 minutes from CBP and CBSA
Current wait: 0 min US-bound · 0 min CA-bound. Data from official CBP (US-bound) and CBSA (CA-bound) feeds, polled about every 15 minutes.
St. Stephen, New Brunswick to Calais, Maine is one of the two main commercial crossings between the Maritimes and the US, carrying seafood, forestry, and general freight into New England. The area has multiple bridge spans, with commercial trucks directed to the designated crossing linking New Brunswick Highway 1 to US-1. Volume is moderate; the main planning factors are the long distances in the region and coastal weather rather than heavy queues. It has no FAST lane, so the Woodstock-Houlton crossing is the option for carriers who want the interstate link.

Skip the booth-side scramble. Both CBP and CBSA require electronic advance notification at least one hour before a commercial truck reaches the border.
Most US-Canada commercial crossings follow the same broad pattern: weekdays are heavier than weekends, mid-week is heavier than Monday or Friday, and daytime hours are heavier than overnights. Specific peak windows vary by port, but the table below is a useful planning baseline. Always check the live wait times above before making routing decisions.
| Time window | Typical congestion |
|---|---|
| Mon–Fri 06:00–10:00 local | Elevated — morning dispatch wave |
| Tue–Thu 10:00–16:00 local | Peak — heaviest commercial volume |
| Fri 14:00–18:00 local | Elevated — weekend repositioning |
| Weekday 22:00–05:00 local | Light — fastest crossings |
| Weekends & statutory holidays | Light — minimal commercial queue |
If St. Stephen-Calais is backed up, these crossings may be faster alternatives. Live wait times for each are updated every 15 minutes.
New Brunswick Highway 1 on the St. Stephen side connects to US-1 on the Calais, Maine side. It is one of the two principal commercial crossings between the Maritimes and New England, carrying seafood, forestry, and general freight.
St. Stephen-Calais (Highway 1 to US-1) is the coastal routing toward Down East Maine; Woodstock-Houlton (Highway 95 to I-95) is the choice when you need a direct interstate link inland. Neither has a FAST lane, so compare the live wait times and your destination routing.
Commercial truck volumes at most US-Canada crossings peak mid-week (Tuesday through Thursday) during daytime business hours. Monday mornings and Friday afternoons also see elevated delays as carriers reposition for the workweek. Weekends and overnight hours are generally the lightest. Live wait times above reflect actual current conditions, which can deviate from these patterns during holidays, weather events, or inspection surges.
Wait times are published directly by the border agency responsible for each direction of travel: US Customs and Border Protection (CBP) for US-bound commercial traffic and the Canada Border Services Agency (CBSA) for Canada-bound traffic. Values represent the estimated delay between joining the back of the truck queue and reaching the primary inspection booth. BorderPro polls the official feeds every 15 minutes.
US-bound commercial trucks need an ACE eManifest submitted to CBP at least one hour before arrival. Canada-bound trucks need an ACI eManifest submitted to CBSA one hour before arrival. Drivers should also carry the appropriate PARS or PAPS lead sheet, commercial invoice, and any commodity-specific permits.
FAST lane availability changes — confirm with CBP and CBSA before relying on it for this crossing. The FAST (Free and Secure Trade) program offers expedited processing at participating commercial ports for pre-approved carriers and drivers.
US-bound shipments use CBP port code 0115. Canada-bound shipments use CBSA FPOA code 0303. These codes are required on eManifest filings and customs documentation — BorderPro fills them in automatically when you select St. Stephen-Calais on a manifest.
Wait time data comes directly from the official border agencies and reflects measured queue conditions at the time of the most recent poll. Conditions can change quickly — a single inspection hold can add 30+ minutes within a 15-minute window. Use live wait times as a planning baseline, not a guarantee, and build in buffer for inspections, paperwork holds, and weather.
