Again, thank you for the question.
I mentioned that in the late 1980s, we deregulated our air sector through initiatives such as the privatization of Air Canada. In the mid-1990s, we further deregulated the air sector in the creation of airport authorities, actions that resulted in the creation of Nav Canada.
I want to be clear that final responsibility for the safety of Canada's air sector remains with the minister, in that it's largely achieved through the regulatory oversight that my colleagues in civil aviation undertake. Responsibility for safety remains with the minister. However, the implementation of it is done through entities such as Nav Canada and the airport authorities.
