In the process, there is no authority for Transport Canada to tell the carrier they're clear to go. There is only a provision that allows Transport Canada to issue an emergency direction. What you've described does not exist in law. Transport Canada, as far as I can see from what you've described, does not have a green-light mechanism; it only has a red light. All Transport Canada is going to do is put up their hands and say I'm sorry, we can't make up our minds.
