No, as I repeated, we do not make use of the American list. The only instance when a flight in Canada may be diverted to Canadian airspace would be if it was an international flight that might come into American airspace. When it is in American airspace, it would be subject to American rules. So if there is potentially a person on the U.S. no-fly list who is going through the American airspace, the Americans may request that the flight not enter American airspace on its flight from an international destination to Canada.
