Canada-U.S. borders brace for busiest day of summer

Border wait times may be lengthy today as the Quebec construction holiday comes to a close and vacationers head back across the Canada-U.S. border.

More than 155,000 Quebecers were on vacation over the past two weeks, making today the busiest day of the year at the province’s border crossings: Stanstead, St-Armand/Philipsburg and St-Bernard-de-Lacolle.

More than 35,000 vehicles are expected to cross at the Lacolle border crossing, just south of Montreal.

The Canada Border Services Agency said it deployed extra personnel today to handle the influx of travellers.

The agency expects longer wait times later in the afternoon and into the evening. It estimates up to a two-hour wait at peak crossing time.

The CBSA is asking travellers to have their passports readily available and to consult its website for real-time wait times to plan their trip back home accordingly.
