US Flights Cancelled at Montreal Airport Due to Construction Odour

Flights to the United States were cancelled from Montréal-Pierre Elliott Trudeau International Airport on July 29, 2026, after painting work at the facility created an odour that disrupted operations. According to CTV News, the cancellations occurred as a result of the scent emanating from construction activities within the airport.

Painting Construction Causes U.S. Flight Cancellations

The disruption centered on flights bound for the United States. CTV News reported that the airport experienced an odour stemming from painting related to ongoing construction, which led to the cancellation of these specific departures. The report indicates that the smell was significant enough to impact the operational capacity of the terminal for U.S.-bound travel.

Montréal-Pierre Elliott Trudeau International Airport serves as a primary hub for travel between Quebec and the U.S. east coast. The cancellation of these flights creates immediate logistical challenges for passengers and airlines operating out of the facility.

Operational Impact at Trudeau International

While the specific number of cancelled flights was not detailed in the initial report, the impact was isolated to U.S. destinations. The odour was attributed directly to painting materials used during construction projects currently underway at the airport. The facility has not provided further details on the specific chemicals or paint types involved in the incident.

Airport authorities typically manage construction schedules to avoid peak travel times, but the emergence of the odour during active flight windows resulted in the decision to halt certain operations. This measure ensures that air quality and passenger comfort meet safety standards before flights are cleared for departure.
