Air Canada will suspend all service to the United States after April 26, following an agreement between the U.S. and Canadian governments to extend border restrictions by 30 days. If there are no further restrictions, Air Canada plans to resume service to the United States on May 22. Air Canada already has been operating less than 10 percent of its regular schedule, but it had maintained limited service to 11 U.S. destinations, mostly for repatriation services.
