Individual airlines are responsible for the cleanliness of their aircraft. Travellers with questions related to methods of cleaning airplanes are advised to reach out to specific airlines to better understand the precautions that have been put in place.
It is important to note that under the federal Quarantine Act, airlines are encouraged to advise PHAC if they have ill passengers on board before arrival in Canada. This allows PHAC to put in place appropriate measures for ill passengers before the aircraft arrives.
