Air Canada said operational disruption had begun before either side issued a formal strike or lockout notice in September 2024. The airline was positioning aircraft, restricting some cargo and cancelling selected holiday products because a safe shutdown of a global network could not be completed at the instant a labour stoppage began.
A legal deadline approached
After a federal cooling-off period, Air Canada or the Air Line Pilots Association could issue 72 hours’ notice beginning at 12:01 a.m. Eastern on September 15. A strike or lockout could therefore start as early as September 18.
Negotiations covering more than 5,200 Air Canada and Air Canada Rouge pilots continued.
The airline planned a three-day wind-down
Air Canada and Rouge operated close to 670 flights and carried more than 110,000 passengers on an average day. Management said progressive cancellations would allow aircraft and crews to return to suitable bases rather than strand them around the world.
A complete shutdown could take three days and restart could take seven to ten.
Cargo felt the earliest effect
The carrier began limiting acceptance of live animals, perishables and other time-sensitive shipments whose normal journeys extended into the possible stoppage. Accepting cargo that could not reach its destination would create welfare, spoilage and supply-chain risks.
Those restrictions justified saying disruption had begun even while passenger flights still operated.
Some holiday packages were adjusted
Air Canada Vacations cancelled or changed selected plans, and some aircraft positioning began before September 15. These preparatory actions were smaller than a network shutdown but affected real customers.
Travellers needed flight-specific confirmation rather than assuming every booking was cancelled.
A goodwill policy offered flexibility
Customers booked between September 15 and 23 could change travel without the normal fee or retain credit under the airline’s policy. If Air Canada cancelled a flight, passengers were eligible for a refund.
Alternative-airline capacity was expected to be limited during a system-wide interruption.
Air Canada Express was different
Regional flights operated by third-party carriers Jazz and PAL Airlines were expected to continue. However, they carried only about one fifth of Air Canada’s customers, and many passengers connected to mainline flights that could still be cancelled.
A regional segment operating did not guarantee completion of an itinerary.
Pay and working conditions drove the dispute
The pilots sought to narrow compensation differences with major United States airlines and update scheduling provisions after lengthy negotiations. Air Canada described the wage demands as excessive and urged arbitration, while the union emphasized bargaining for a competitive contract.
Each side’s characterization was advocacy, not a neutral account.
The public faced regulatory limits
Canadian passenger rules generally classify labour disruption outside the carrier’s control for compensation purposes, though refund, rebooking and information duties still apply. Rights can also depend on the cause and sequence of a specific cancellation.
Passengers should keep notices and receipts rather than rely on general summaries.
A last-minute agreement prevented the shutdown
On September 15, Air Canada and ALPA announced a tentative four-year collective agreement, subject to pilot ratification and board approval. Normal operations continued, and customers who had moved eligible flights could seek to restore their original booking if space remained.
The disruption warning was not a false alarm: advance planning had already changed cargo and travel products. But the final outcome also mattered. Negotiation prevented the progressively larger cancellations that both sides had spent the week preparing to manage.
