Air Canada reached a tentative four-year collective agreement with the International Association of Machinists and Aerospace Workers covering 11,000 Technical Operations, Maintenance, and Operational Support employees, effective 1 April 2026 through 31 March 2030. The deal, announced 13 July 2026 in Montréal, is the sixth collective agreement the carrier secured this year, reinforcing maintenance reliability and cargo/logistics efficiency while mitigating AOG risks from labor disputes. Ratification by IAMAW membership is pending over the coming days. The contract formally recognizes TMOS skills critical to aircraft safety and operational continuity, addressing prior sector tensions that triggered strike votes at operators like WestJet. Final wage and benefit specifics remain undisclosed pending ratification.
