The 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, Ontario. As the aircraft commenced 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 and hold short of Runway 30.
Moments later, 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 issued an immediate instruction to CJT628 to abort takeoff. The flight crew executed a high-speed rejected takeoff and successfully brought the aircraft to a stop near Taxiway Charlie.
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 departed without further incident. The TSB is investigating.

Class of investigation
This is a class 3 investigation. These investigations analyze a small number of safety issues, and may result in recommendations. Class 3 investigations are generally completed within 450 days. For more information, see the Policy on Occurrence Classification.
TSB investigation process
There are 3 phases to a TSB investigation
- Field phase: a team of investigators examines the occurrence site and wreckage, interviews witnesses and collects pertinent information.
- Examination and analysis phase: the TSB reviews pertinent records, tests components of the wreckage in the lab, determines the sequence of events and identifies safety deficiencies. When safety deficiencies are suspected or confirmed, the TSB advises the appropriate authority without waiting until publication of the final report.
- Report phase: a confidential draft report is approved by the Board and sent to persons and corporations who are directly concerned by the report. They then have the opportunity to dispute or correct information they believe to be incorrect. The Board considers all representations before approving the final report, which is subsequently released to the public.

The TSB is an independent agency that investigates air, marine, pipeline, and rail transportation occurrences. Its sole aim is the advancement of transportation safety. It is not the function of the Board to assign fault or determine civil or criminal liability.
