An evening flight from British Columbia to Toronto this week had to be canceled because a toddler refused to buckle their seat belt, the airline confirmed to Fox News Digital.

Porter Airlines flight 444 was expected to leave from Victoria International Airport at 10:30 p.m. and had begun taxiing when a flight attendant noticed the child.

"A young child was standing in their seat and would not secure their seatbelt," the airline shared with Fox News Digital in a statement, adding that neither the adult with the child nor the crew were able to get the child buckled.

"The aircraft could not take off in this unsafe condition, so the crew elected to return to the terminal and have the passengers disembark," the airline added.

Because the airport has a takeoff curfew of 12:30 a.m., and it took time to get the passengers in question and their luggage off the plane and do the necessary paperwork, the flight had to be canceled, and the other passengers had to stay the night.

The other passengers were rebooked on a Friday flight.

"We apologize for the effect this had on other passengers," Porter added.

A child safety seat or restraint device is required for children under two flying on the airline. It’s unclear how old the child was.
