Air Canada flights will resume on Saturday evening, as a strike by its 10,000 cabin crew came to an end. The Canadian Industrial Relations Board (CIRB) told the airline's staff to return to work and said that an expired collective agreement would be extended until a new one was agreed.

The Canadian Union of Public Employees contends that the government’s decision on Saturday to end the strike by taking it to binding arbitration is itself illegal and violates its members’ constitutional right to strike. It filed an application for an injunction to block the back to work order with the Federal Court of Canada over the weekend.

The Canada Industrial Relations Board has declared a strike by 10,000 Air Canada flight attendants illegal and ordered them back on the job after they ignored an earlier order to return to work and submit to arbitration.
