Air Canada has already resumed flights after its major strike disruption in August 2025, and operations are now largely back to normal, with some routes still being restored or adjusted seasonally.

Quick Scoop: When will Air Canada resume flights?

The core update

  • Air Canada’s large-scale suspension of flights in August 2025 due to the flight attendant strike ended when the airline reached a mediated settlement with the union.
  • The first flights restarted on the evening of August 19, 2025, with the airline warning that full, regular service would take about 7–10 days to stabilize as crews and aircraft were repositioned.
  • By early September 2025, the carrier was actively “getting planes back in the skies” with over 150 flights a day from major hubs like Toronto, Montreal, and Vancouver, including international services.
  • As of 2026, Air Canada is not in a generalized shutdown; instead, it is announcing route expansions and seasonal resumptions (for example, resuming certain winter and sun destinations later in 2026).

If you’re wondering “when will Air Canada resume flights,” in a broad sense, the answer is: they already have, and the network has been largely rebuilt since late August 2025, with ongoing tweaks by route and season.

What “resume flights” actually means now

Because “when will Air Canada resume flights” can mean different things, it helps to break it down:

  1. After the 2025 strike shutdown
    • The strike by about 10,000 flight attendants led to widespread cancellations and grounded much of Air Canada and Air Canada Rouge.
 * A government-backed process pushed both sides into mediation and effectively ordered a return to work, opening the door for flights to resume.

 * Air Canada’s official statement said the first flights would depart on August 19, 2025, with full normalization requiring “a week or more.”
  1. During the ramp‑up phase
    • The airline described restarting as a “complex undertaking,” noting that aircraft and crews were out of position after days on the ground.
 * Early departures included international and key North American routes, then expanded to domestic, U.S., and long‑haul flights over several days.

 * Most domestic and U.S. flights were expected to be operational within about 10 days, though some disruption (delays and cancellations) lingered.
  1. Route‑by‑route resumption
    • Separate from the strike issue, Air Canada continues to “resume” and adjust specific routes as part of its seasonal and strategic schedule planning, including resuming certain routes earlier in the 2026 winter season compared with 2025.
 * That means the exact answer for you depends on _which_ route or region you care about (e.g., Europe, sun destinations, South America).

What you can do right now

If you’re trying to figure out whether your specific flight or route has resumed:

  1. Check Air Canada’s travel updates page
    • Air Canada maintains a travel news and updates section that highlights service changes, notices, and sometimes route launches or resumptions.
  1. Search by route and date
    • On the booking engine, plug in your origin, destination, and approximate travel date.
    • If flights show as bookable, that’s the clearest sign that service on that route is running or scheduled to run. (Air Canada itself advises customers to rely on live status and bookings when deciding whether to go to the airport.)
  1. Watch for special press releases
    • When Air Canada resumes or adds notable routes (for example, new or returning international destinations), it typically issues a press release with the start/resume date clearly stated.

Example:
If you’re looking at a seasonal leisure route, you might see wording like “Flights resume October 24, 2026,” which indicates the first day that route comes back into operation for the next season.

Mini forum-style viewpoints

If this were playing out on a travel or Canada-focused forum, you’d likely see takes like:

“Technically, flights have already resumed after the 2025 strike. The real question is whether your route is back in the schedule yet.”

“Check the booking calendar — if you can buy a ticket, that’s more reliable than any headline. The airline’s been slowly normalizing since late August 2025.”

“Remember that ‘resume flights’ can mean a lot of things: end of strike, restart of a seasonal sun route, or re-launch of a long-haul international service.”

These perspectives reflect how travelers often experience airline “resumptions”: less as a single date, more as a rolling return of specific routes and frequencies over time.

TL;DR

  • The big strike-related shutdown ended in August 2025, with flights restarting from August 19 and normalizing over roughly 7–10 days.
  • By early September 2025, Air Canada was actively relaunching a large slate of domestic and international flights.
  • In 2026, Air Canada is operating and also announcing specific route resumptions and expansions (for example, some flights resuming in October 2026).
