For over half a century, Canadians have been travelling over U.S. airspace without having to suffer a violation of their rights to control their private information, without being forced to send their personal information to U.S. authorities and to ask for permission from the American government if they want to travel to Mexico, Cuba, or South America.
In that time, in over 50 years, the security record of Canadians travelling over U.S. airspace, to my mind, has been about as close to 100% as you're going to get.
Is there any factual basis to justify this legislation?
