Air Canada began canceling flights Thursday ahead of a possible strike by its 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.

Jobs Minister Patty Hajdu is urging Air Canada and the union representing its flight attendants to get back to the negotiating table, suggesting she's not ready to intervene in a dispute that has upended hundreds of flights.

As Air Canada cancels flights in anticipation of a possible strike, experts say this could result in millions of dollars of delayed claims.
