Air Canada Flight AC774 Veers Off Taxiway at Montreal Trudeau Airport: TSB Launches Investigation

Background & Timeline

Air Canada Flight AC774 departed Los Angeles International Airport (LAX) and arrived at Montreal-Pierre Elliott Trudeau International Airport (YUL) shortly before 4:00 PM on July 9, 2026. According to flight tracking data from FlightRadar24, the Boeing 737 Max 8 landed on Runway 6 Left and proceeded onto Taxiway B1. The aircraft then overshot a 150-degree right turn onto Taxiway B — which runs parallel to the runway — ending up on the grass.

Passenger Experience

Passenger Barbara Edelston Peterson described the ordeal to CBC, stating the aircraft was "going very fast" upon landing. She reported a "big smoke smell" followed by the sensation of "tumbling on the grass." Smoke, dirt, and grass obscured her window view, and passengers feared the aircraft might catch fire. Passengers remained onboard for approximately three hours before being transported to the terminal via buses. Peterson praised the crew's professionalism, calling them a "class act."

Investigation & Response

The TSB confirmed it has deployed investigators to gather information and assess the accident. Air Canada stated it is conducting its own detailed investigation and will collaborate with authorities to determine causation. Nav Canada, the civil air navigation service provider, implemented traffic management measures including a temporary ground stop and flow restrictions to safely manage arrivals and departures.

The aircraft was scheduled to continue to San Francisco that evening and return to Montreal the following morning — both flights were cancelled. The plane was towed to a hangar for full inspection.

Historical Context

Runway excursions — where an aircraft leaves the paved surface — are classified by the International Civil Aviation Organization (ICAO) as a leading safety concern. Data from the Flight Safety Foundation indicates that adverse weather, particularly wet runways, is a contributing factor in approximately 40% of such incidents. While modern aircraft like the Boeing 737 Max are equipped with advanced braking systems, weather conditions remain a significant variable.

Were there any injuries during the incident?

No. All 156 passengers and 6 crew members were safely evacuated with no reported injuries.

What caused the plane to veer off the taxiway?

The exact cause is under investigation by the TSB and Air Canada. Heavy rain at the time of landing is considered a contributing factor, but no official determination has been made.

How long was the runway closed?

Runway 6L/24R was closed for approximately 6 hours, reopening around 9:45 PM on July 9, 2026.

Were other flights affected?

Yes. Domestic flights experienced delays of about 30 minutes, while U.S.-bound flights saw delays of 45 minutes to an hour. No flight cancellations were directly attributed to the incident.

What type of aircraft was involved?

A Boeing 737 Max 8, registered as Air Canada Flight AC774.
