Air Canada is close to a potential shutdown unless the airline and its flight attendants can reach a last-minute deal in their labour dispute.

Flight attendants are poised to walk off the job at 1 a.m. Eastern, leaving thousands of travellers scrambling to deal with the disruption. Neetu Garcha has more.
