On January 3, 2024, a dispute within a family escalated into violence on board an Air Canada flight from Toronto to Calgary. The captain decided to make a stopover in Winnipeg to hand the troublemakers over to the police. The Airbus A321 with the registration C-GIUE initially took off routinely from Toronto's Pearson Airport. At first it looked like a quiet flight, but about 30 minutes after takeoff an argument broke out between a 16-year-old youth and his relatives who were flying with him. The exact degree of relationship was not disclosed, so it is unclear whether it was his parents or, for example, his grandparents. After initially making loud statements from the minor, fists flew. He violently attacked his relatives. They are said to have suffered injuries, which is why outpatient treatment was necessary after landing. The flight attendants and other passengers intervened and were able to bring the teenager under control. However, this did not change the fact that the captain decided, for safety reasons, that the family dispute should be resolved outside the aircraft he was commanding. He therefore decided to make an unscheduled stopover in Winnipeg. The teenager was already awaited by the police there, who took him away. His relatives also had to leave the Airbus A321. The teenager was taken to a hospital. A psychiatric examination is to be carried out there on the orders of the public prosecutor. It is completely unclear - and was not disclosed by the authorities - what caused the teenager to lose his nerve and violently attack his relatives.
