Firefighters were called in to evacuate the plane. Canadian media reported close to 10 passengers had been shifted to the hospital.

What is de-icing?

De-icing is the process of removal of snow, ice or frost from a surface. Anti-icing agents are used, mostly chemicals to de-ice surfaces and also delay the reformation of ice for certain periods.



De-icing of an aircraft is crucial. Ice can contaminate or disturb the airflow degrading the ability of the wings to lift, this can also cause a crash. If large pieces of ice seperate when the aircraft is in motion they can be ingested by the engine or hit the propellers and cause failure.
