I'll start that, Kevin, and then you may want to pick up on it.
Mr. Chair, the question is very topical.
NavCan has launched consultations and studies looking at adjusting the level of service for a range of aerodromes. The process by which the minister comes to a view as to the safety of it is a process that is carried out completely by the safety experts in the civil aviation directorate at Transport Canada.
NavCan has to submit studies fully assessing the implications of any proposed level of service change, and there's a very careful review in the civil aviation directorate. If there's an issue with respect to aviation safety, they will deny the proposed level of service change.
While in legislation it says the minister, as I said, it's a technical safety assessment carried out by civil aviation officials.
