Air Canada reversed course on plans to resume flights on Sunday despite the government ordering more than 10,000 cabin crew to end a strike that led to hundreds of cancellations.

Air Canada has reached an agreement with the union representing more than 10,000 flight attendants and cabin crew to end a pay strike that has disrupted peak summer travel. The country’s largest carrier and the Canadian Union of Public Employees said on Tuesday that flights would be gradually restored from the evening.
