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.

The union representing around 10,000 Air Canada flight attendants issued a 72-hour strike notice Wednesday. In response, the airline issued a lockout notice.

Mark Nasr, chief operations officer for Air Canada, said the airline has begun a gradual suspension of Air Canada and Air Canada Rouge operations. "All flights will be paused by Saturday early morning," he said.
