The Airbus A320 was carrying 133 passengers and five crew. Police and the airport said 25 people were taken to hospital with non life-threatening injuries.
However, an Air Canada update said 23 passengers and crew were hospitalized, and by Sunday afternoon all but one of the admitted have been released.
"We at Air Canada are greatly relieved that no one was critically injured. We will also fully cooperate with the Transportation Safety Board as it begins an investigation to determine the cause," Klaus Goersch, the airline's Executive Vice President and Chief Operating Officer, said in a statement.
