Airline cancels flight after child refuses to sit down and buckle up

Porter Airlines cancelled a flight and rebooked passengers for the following day after a child refused to sit down and buckle up. The Toronto-based airline reported that both the parent and the crew made repeated, unsuccessful attempts to secure the child in their seat. Consequently, the aircraft was returned to the terminal. This decision followed the failure to ensure the child's safety through the required seating and buckling procedures during the flight's initial phase.
