Air Canada Faces 19 Flight Cancellations And 92 Delays, Disrupting Passengers Across Canada At Calgary, Montreal–Trudeau, Halifax, Toronto Pearson, And More

Air Canada reported 92 delayed flights, representing 16 percent of its scheduled operations today, alongside 19 cancellations affecting both domestic and international services. The disruptions impacted major hubs including Toronto Pearson, Montreal–Trudeau, Halifax, and Calgary, while also extending to transborder and long-haul international routes.
The affected flights included narrowbody and widebody aircraft operations, touching key corridors within Canada and connections to the United States, the Caribbean, and Europe.
Toronto and Montreal Routes See Significant Impact
Several cancellations were concentrated around Toronto Pearson International Airport (CYYZ) and Montreal–Trudeau International Airport (CYUL), two of Air Canada’s most critical hubs.
Cancelled services included:
- ACA400 from Toronto Pearson to Montreal–Trudeau
- ACA661 from Halifax to Montreal–Trudeau (cancelled on consecutive days)
- ACA668 from Montreal–Trudeau to Halifax
- ACA317 from Montreal–Trudeau to Calgary
- ACA322 from Calgary to Montreal–Trudeau
The repeated cancellation of ACA661 on both Wednesday and Thursday highlights continued operational pressure on the Halifax–Montreal corridor. Toronto–Montreal and Halifax–Montreal routes are key domestic links, and their disruption likely created ripple effects across connecting itineraries.
In addition, ACA603 from Halifax to Toronto Pearson and ACA618 from Toronto Pearson to Halifax were cancelled, further affecting traffic between Ontario and Nova Scotia.
Transborder Services Affected
Air Canada’s transborder operations also experienced cancellations. Among the affected routes were:
- ACA767 from Boston Logan to Toronto Pearson
- ACA585 from Newark Liberty to Calgary
- ACA1205 from Miami International to Montreal–Trudeau
These cancellations disrupted passenger flows between Canada and major U.S. cities, particularly Boston, Newark, and Miami. The Boston–Toronto and Miami–Montreal routes are important business and leisure corridors, and their suspension added pressure to already strained schedules.
Long-Haul and Leisure Destinations Disrupted
International long-haul services were not spared. Widebody aircraft cancellations included:
- ACA785 and ACA791 from Toronto Pearson to Los Angeles International
- ACA878 from Montreal–Trudeau to Toulouse-Blagnac
- ACA879 from Toulouse-Blagnac to Montreal–Trudeau
- ACA947 from Punta Cana to Montreal–Trudeau
The cancellation of ACA878 and ACA879 effectively disrupted both directions of the Montreal–Toulouse route, impacting transatlantic travel plans. Similarly, the Punta Cana service affected Caribbean-bound and returning passengers.
Leisure-focused routes to Cuba were also hit:
- ACA1426 from Toronto Pearson to Jardines del Rey
- ACA1420 from Montreal–Trudeau to Jardines del Rey
- ACA1400 from Toronto Pearson to Juan Gualberto Gomez International
The grounding of multiple Cuba-bound flights signals notable impact on vacation travel flows from both Toronto and Montreal.
Fleet Mix Reflects Broad Operational Strain
The cancelled flights involved a range of aircraft types, including:
- Airbus A320 and A321 narrowbody aircraft
- Boeing 737 MAX 8 (B38M)
- Boeing 777-300ER (B77W)
- Boeing 787 Dreamliner variants (B788 and B789)
The presence of widebody aircraft such as the Boeing 777 and Boeing 787 among cancelled services indicates that disruptions extended beyond short-haul rotations into long-haul intercontinental operations.
Concentration Across Major Canadian Hubs
Toronto Pearson and Montreal–Trudeau featured prominently among the cancellations, reflecting the central role these airports play in Air Canada’s network structure. Halifax and Calgary also saw multiple affected services, while international endpoints including Los Angeles, Miami, Newark, Boston, Punta Cana, Toulouse, and Cuban destinations were drawn into the disruption cycle.
With 92 delayed flights accounting for 16 percent of operations and 19 cancellations across domestic, transborder, and international routes, Air Canada’s schedule experienced measurable disruption across multiple regions.
Passengers traveling through Toronto, Montreal, Halifax, and Calgary faced the brunt of operational changes, while those on long-haul and leisure routes encountered cancellations affecting both outbound and inbound journeys.
