Yes, I guess I would try to clarify that. There is a specific weight certification of aircraft that are flown commercially and that is dictated by the regulations in Canada for IF—instrument flight—rules. These aircraft must have anti-collision detection technology. That would be the majority of all of the commercial traffic within major Canadian airports and many smaller Canadian airports, but aircraft flying within visual flight rules, which may be independently owned or operated, do not have that technology at present.
We will be, over the course of the next several years, working with Transport Canada and Nav Canada, as well as all of the operations in Canada, flight schools included, to try to determine whether we feel ADS-B transponder equipage should be mandated in certain classes of airspace in Canada. It's unknown yet where that specifically will be and how that will be supported within industry.
