Occurrence
On 25 February 2026, a Boeing 757-200 operated by Cargojet as flight CJT628 was cleared for takeoff from Runway 30 at the John C. Munro Hamilton International Airport in Ontario. As the aircraft began its takeoff roll, three snowplows holding short of Runway 12/30 on Taxiway Golf were cleared to proceed via Taxiway Golf and Taxiway Charlie onto Runway 06/24, with instructions to hold short of Runway 30.
Sequence of Events
Shortly thereafter, the air traffic controller observed the snowplows entering Runway 12 between Taxiways Golf and Charlie, moving in the direction of the departing aircraft. The controller immediately instructed CJT628 to abort the takeoff. The flight crew executed a high-speed rejected takeoff and brought the aircraft to a stop near Taxiway Charlie.
Aftermath
Once the aircraft was stationary, the snowplows were observed exiting the runway between the taxiways. The aircraft later taxied back to the airport apron for an inspection and subsequently departed without further incident. The Transportation Safety Board of Canada is investigating this occurrence as a Class 3 investigation, focusing on a small number of safety issues.
