No, I'm sorry, we can't.... I'm sorry, there is no such thing as “by default”. Either the regulations have a regime that causes Transport Canada to give a green light or an emergency direction, or they're defective and the citizen will not have the certainty of being able to board the flight--unless you think there are civil servants out there who are going to be empowered to give green lights. I have never found a civil servant in my life who was able to give a green light unless they had the authority to do so.
