A flight in Canada was canceled due to a safety precaution. The issue arose when a young child refused to put on their seat belt during preparations for takeoff. The child's parents and cabin crew attempted to buckle the child in, but were unsuccessful.

As a result, the plane was unable to take off and returned to the terminal. Further details about the incident are available from the source, including the specific airport and airline involved. The incident occurred on a Thursday, but the exact outcome and any subsequent actions taken are not specified in the available information.
