Obviously, Transport Canada has oversight on this issue.
As I said before, the ability to have a well-trained controller providing air traffic separation and control into an airport reduces the risk overall. It increases the efficiency of the operation, as well as reducing the carbon footprint.
Needless to say, our crews don't operate if it's not deemed safe, but other procedures and delays and so on impact the operation. Ideally, having controllers at our airports is obviously the right answer and the best risk management possible.
