Opening hours are being extended at 39 border crossings with the United States and at several airports across the country as the Canada Border Services Agency returns to pre-pandemic hours.

The changes will take effect on March 31.

The border agency first restricted hours at land border crossings in April 2020, closing many points of entry early and stopping 24-hour service at seven crossings.

Six crossing points in Quebec and the Regway crossing in Saskatchewan will again be open 24 hours a day, seven days a week.

The three airports getting updated hours are Whetstone International Airport in Del Bonita, Alta., Piney Pinecreek Border Airport in Piney, Man., and Scobey Border Station Airport in Coronach, Sask.

The news comes days after U.S. President Joe Biden’s visit to Ottawa for meetings with Prime Minister Justin Trudeau on cross-border issues.
