Sumas-Abbotsford border wait time history
What ten years of hourly CBSA readings show about waits into Canada at Sumas-Abbotsford, labelled as pre-2020 data.
Pre-2020 data. This is the CBSA’s published hourly series for Canada-bound travellers at Abbotsford-Huntingdon, from 2010-04-01 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 87085 readings of the passenger-vehicle wait at Sumas-Abbotsford, one roughly every hour. In 85% 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, 513 readings); Sunday 16:00 the highest (10 min, 553 readings).

Recorded readings since 2026
