It's the final day before a potential work stoppage could ground all Air Canada and Air Canada Rouge flights. More than 10,000 flight attendants are poised to walk off the job around 1 a.m.

Air Canada says it is beginning a "phased wind down" of most of its operations after thousands of flight attendants voted to strike.

TORONTO — Air Canada started canceling flights on Thursday ahead of a possible work stoppage by flight attendants that could impact hundreds of thousands of travelers. A complete shutdown of the country’s largest airline threatens to impact about 130,000 people a day.
