Thank you for the question.
With regard to Castlegar, it used to be an air traffic control tower. Now it's an airport advisory service. It is on Nav Canada's list to stop providing service there. This is where flight service specialists work. They provide a weather advisory and advise pilots and airport users on what's going on at a specific time.
Air traffic control is a different service. We provide actual separation to all airplanes. We make the decision for the pilot, more or less, allowing them to worry about flying the airplane and not what's going on around them.
With regard to how difficult it is to fly into places such as Castlegar, Whitehorse and mountainous areas, without the services provided by flight services and air traffic control, it makes it extremely difficult. I believe that Mr. Giguere, a very experienced pilot, can answer this all for himself, but it absolutely makes...safety is paramount.
