Sweetgrass-Coutts border wait time history
What ten years of hourly CBSA readings show about waits into Canada at Sweetgrass-Coutts, labelled as pre-2020 data.
Pre-2020 data. This is the CBSA’s published hourly series for Canada-bound travellers at Coutts, from 2010-03-31 to 2020-03-31. It shows a pattern by weekday and hour, not today’s waits: traffic, staffing and lanes have changed since 2020.
What the ten years show
The series has 92129 readings of the passenger-vehicle wait at Sweetgrass-Coutts, one roughly every hour. In 98% of the 168 weekday-hour slots the median reading was 0 minutes, so the median alone hides the busy periods; the 90th percentile (one reading in ten was this long or longer) shows them. Over April 2010 to March 2020, Sunday 00:00 had the lowest median passenger-vehicle wait (0 min, 538 readings); Friday 14:00 the highest (5 min, 538 readings).

Recorded readings since 2026
Since October 2026 we also record the live CBP and CBSA figures every 30 minutes. Our own weekday-by-hour chart replaces the pre-2020 pattern here once at least 28 days exist; until then the live panel on the Sweetgrass-Coutts wait page is the current figure.
