TORONTO (AP) — The union for Air Canada’s 10,000 flight attendants said early Tuesday that it has reached a tentative agreement to end a strike.

Air Canada and the union resumed talks late Monday for the first time since the strike began over the weekend. The strike is affecting about 130,000 travelers a day at the peak of the summer travel season.

The union said the agreement will guarantee members pay for work performed while planes are on the ground, resolving one of the major issues that drove the strike.

“Unpaid work is over. We have reclaimed our voice and our power,” the union said in a statement. “When our rights were taken away, we stood strong, we fought back — and we secured a tentative agreement that our members can vote on.”

It followed the union’s declaration that the flight attendants wouldn’t return to work even though the strike was declared illegal.

Earlier, Air Canada said rolling cancellations would now extend through Tuesday afternoon after the union defied a second return-to-work order.

The Canada Industrial Relations Board had declared the strike illegal Monday and ordered the flight attendants back on the job. But the union said it would defy the directive. Union leaders also ignored a weekend order to submit to binding arbitration and end the strike by Sunday afternoon.

The board is an independent administrative tribunal that interprets and applies Canada’s labor laws. The government ordered the board to intervene.

Labor leaders objected to the Canadian government’s repeated use of a law that cuts off workers’ right to strike and forces them into arbitration, a step the government took in recent years with workers at ports, railways and elsewhere.

Air Canada operates around 700 flights per day. The airline estimated Monday that 500,000 customers would be affected by flight cancellations.

Aviation analytics firm Cirium said that as of Monday afternoon, Air Canada had called off at least 1,219 domestic flights and 1,339 international flights since last Thursday, when the carrier began gradually suspending its operations ahead of the strike and lockout.

Flight attendants walked off the job early Saturday, after turning down the airline’s request to enter into government-directed arbitration, which allows a third-party mediator to decide the terms of a new contract.

Air Canada and CUPE have been in contract talks for about eight months but remain far apart on the issue of pay and the unpaid work that flight attendants do when planes aren’t in the air.

The airline’s latest offer included a 38% increase in total compensation, including benefits and pensions, over four years, that it said “would have made our flight attendants the best compensated in Canada.”

But the union pushed back, saying the proposed 8% raise in the first year didn’t go far enough because of inflation.

Passengers whose flights are impacted will be eligible to request a full refund on the airline’s website or mobile app, according to Air Canada.

TORONTO (AP) — Air Canada suspended plans to restart operations Sunday after the union representing 10,000 flight attendants said it will defy a return to work order. The strike was already affecting about 130,000 travelers per day during the peak summer travel season.

The Canada Industrial Relations Board ordered airline staff back to work by 2 p.m. Sunday after the government intervened and Air Canada said it planned to resume flights Sunday evening.

Canada’s largest airline now says it will resume flights Monday evening. Air Canada said in a statement that the union “illegally directed its flight attendant members to defy a direction from the Canadian Industrial Relations Board.”

“Our members are not going back to work,” Canadian Union of Public Employees national president Mark Hancock said outside Toronto’s Pearson International Airport. “We are saying no.”

Hancock ripped up a copy of the back-to-work order outside the airport’s departures terminal where union members were picketing Sunday morning. He said they won’t return Tuesday either.

Flight attendants chanted “Don’t blame me, blame AC” outside Pearson.

“Like many Canadians, the Minister is monitoring this situation closely. The Canada Industrial Relations Board is an independent tribunal,” Jennifer Kozelj, a spokeswoman for Federal Jobs Minister Patty Hajdu said in a emailed statement.

Hancock said the “whole process has been unfair” and said the union will challenge what it called an unconstitutional order.

Less than 12 hours after workers walked off the job, Hajdu ordered the 10,000 flight attendants back to work, saying now is not the time to take risks with the economy and noting the unprecedented tariffs the U.S. has imposed on Canada. Hajdu referred the work stoppage to the Canada Industrial Relations Board.

The airline said the CIRB has extended the term of the existing collective agreement until a new one is determined by the arbitrator.

The shutdown of Canada’s largest airline early Saturday was impacting about 130,000 people a day. Air Canada operates around 700 flights per day.

Tourist Mel Durston from southern England was trying to make the most of sightseeing in Canada. But she said she doesn’t have a way to continue her journey.

“We wanted to go see the Rockies, but we might not get there because of this,” Durston said. “We might have to head straight back.”

James Hart and Zahara Virani were visiting Toronto from Calgary, Alberta for what they thought would be a fun weekend. But they ended up paying $2,600 Canadian ($1,880) to fly with another airline on a later day after their Air Canada flight got canceled.

“It’s a little frustrating and stressful, but at the same time, I don’t blame the flight attendants at all,” Virani said. “What they’re asking for is not unreasonable whatsoever.”

Flight attendants walked off the job around 1 a.m. EDT on Saturday. Around the same time, Air Canada said it would begin locking flight attendants out of airports.

The bitter contract fight escalated Friday as the union turned down Air Canada’s prior request to enter into government-directed arbitration, which allows a third-party mediator to decide the terms of a new contract.

Last year, the government forced the country’s two major railroads into arbitration with their labor union during a work stoppage. The union for the rail workers is suing, arguing the government is removing a union’s leverage in negotiations.

Hajdu maintained that her Liberal government is not anti-union, saying it is clear the two sides are at an impasse.

Passengers whose flights are impacted will be eligible to request a full refund on the airline’s website or mobile app, according to Air Canada.

The airline said it would also offer alternative travel options through other Canadian and foreign airlines when possible. Still, it warned that it could not guarantee immediate rebooking because flights on other airlines are already full “due to the summer travel peak.”

Air Canada and CUPE have been in contract talks for about eight months, but they have yet to reach a tentative deal. Both sides have said they remain far apart on the issue of pay and the unpaid work flight attendants do when planes aren’t in the air.

The airline’s latest offer included a 38% increase in total compensation, including benefits and pensions, over four years, that it said “would have made our flight attendants the best compensated in Canada.”

But the union pushed back, saying the proposed 8% raise in the first year didn’t go far enough because of inflation.

TORONTO (AP) — Canada’s government forced Air Canada and its striking flight attendants back to work and into arbitration Saturday after a work stoppage stranded more than 100,000 travelers around the world during the peak summer travel season.

Federal Jobs Minister Patty Hajdu said now is not the time to take risks with the economy, noting the unprecedented tariffs the U.S. has imposed on Canada. The intervention means the 10,000 flight attendants will return to work soon.

The government’s action came less than 12 hours after workers walked off the job.

“The talks broke down. It is clear that the parties are not any closer to resolving some of the key issues that remain and they will need help with the arbitrator,” Hajdu said.

Hajdu said the full resumption of services could take days, noting it is up to the Canada Industrial Relations Board.

The shutdown of Canada’s largest airline early Saturday is impacting about 130,000 people a day, and some 25,000 Canadians may be stranded. Air Canada operates around 700 flights per day.

Hajdu ordered the Canada Industrial Relations Board to extend the term of the existing collective agreement until a new one is determined by the arbitrator.

“Canadians rely on air travel every day, and its importance cannot be understated,” she said.

Wesley Lesosky, president of the Air Canada Component of CUPE union, complained in a statement that Hajdu only waited a few hours to intervene and said the government has violated their constitutional right to strike.

“The Liberal government is rewarding Air Canada’s refusal to negotiate fairly by giving them exactly what they wanted,” he said.

Union spokesman Hugh Pouliot didn’t immediately know what day workers would return to work. “We’re on the picket lines until further notice,” he said.

The bitter contract fight between the airline and the union representing 10,000 of its flight attendants escalated Friday as the union turned down the airline’s request to enter into government-directed arbitration, which would eliminate its right to strike and allow a third-party mediator to decide the terms of a new contract.

Keelin Pringnitz, from Ottawa, was returning with her family from a European vacation when they became stranded at London’s Heathrow Airport after flights were canceled. She said there was an option for the travelers in line to go the United States, but they were told there wouldn’t be any further assistance once they landed in the U.S.

“It didn’t go over well with the line. Nobody really seemed interested, everybody seemed a little bit amused almost at the suggestion, or exasperated, because it is a bit ridiculous to offer to take stranded passengers to a different country to strand them there,” she said.

Montreal resident Alex Laroche, 21, and his girlfriend had been saving since Christmas for their European vacation. Now their $8,000 trip with nonrefundable lodging is in doubt. They had a Saturday night flight to Nice, France, booked.

Air Canada Chief Operating Officer Mark Nasr has said it could take up to a week to fully restart operations.

Flight attendants walked off the job around 1 a.m. EDT on Saturday. Around the same time, Air Canada said it would begin locking flight attendants out of airports.

Ian Lee, associate professor, Carleton University’s Sprott School of Business, earlier noted the government repeatedly intervenes in transportation strikes.

“They will intervene to bring the strike to an end. Why? Because it has happened 45 times from 1950 until now,” Lee said. “It is all because of the incredible dependency of Canadians.”

Canada is the second-largest country in the world and flying is often the only viable option.

“We’re so huge a country and it’s so disruptive when there is a strike of any kind in transportation,” Lee said.

The government forced the country’s two major railroads into arbitration with their labor union last year during a work stoppage. The union for the rail workers is suing, arguing the government is removing a union’s leverage in negotiations.

The Business Council of Canada had urged the government to impose binding arbitration in this case, too. And the Canadian Chamber of Commerce welcomed the intervention.

“With valuable cargo grounded and passengers stranded, the government made the right decision to refer the two sides to binding arbitration, said Matthew Holmes, the executive vice president for the Chamber of Commerce. “Every hour counts given Air Canada says it will need up to a week for its network to be fully operationalized again, meaning that close to a million Canadians and international visitors could be impacted.”

Hajdu said her Liberal government is not anti-union, saying it is clear the two sides are at an impasse.

Passengers whose travel is impacted will be eligible to request a full refund on the airline’s website or mobile app, according to Air Canada.

The airline said it would also offer alternative travel options through other Canadian and foreign airlines when possible. But it warned that it could not guarantee immediate rebooking because flights on other airlines are already full “due to the summer travel peak.”

Laroche said he considered booking new flights with a different carrier, but he said most of them are nearly full and cost more than double the $3,000 they paid for their original tickets.

Laroche said he was initially upset over the union’s decision to go on strike, but that he had a change of heart after reading about the key issues at the center of the contract negotiations, including the issue of wages.

“Their wage is barely livable,” Laroche said.

Air Canada and the Canadian Union of Public Employees have been in contract talks for about eight months, but they have yet to reach a tentative deal.

Both sides say they remain far apart on the issue of pay and the unpaid work flight attendants do when planes aren’t in the air.

“We are heartbroken for our passengers. Nobody wants to see Canadians stranded or anxious about their travel plans but we cannot work for free,” Natasha Stea, an Air Canada flight attendant and local union president, said before the government intervention was announced.

The attendants are about 70% women. Stea said Air Canada pilots, who are male dominated, received a significant raise last year and questioned whether they are getting fair treatment.

The airline’s latest offer included a 38% increase in total compensation, including benefits and pensions over four years, that it said “would have made our flight attendants the best compensated in Canada.”

But the union pushed back, saying the proposed 8% raise in the first year didn’t go far enough because of inflation.
