One of the serious issues the world is struggling with is those who travel internationally for the purpose of endangering international air travel, or to get to another part of the world where they intend to engage in terror-related activities. At the moment, we have no systematic way to determine when a person has left the country. We collect that information on foreign nationals. We collect that information on permanent residents, but not on those who are Canadian citizens. So there's a big hole in our data collection system.
It's very useful for police and security services to be able to identify when people have left the country. If there is a suspicion about the activity that individuals may be engaged in, the police authorities and the security authorities will at least have that extra piece of information that says they are no longer in Canada. There's a lot more to the process of dealing with travellers who would either endanger air transportation or try to get to a part of the world where they intend to engage in terrorist activity, but knowing where they are is a critical piece of information.
There's another element too. When a person is attempting to board an aircraft, you have those precious few minutes or hours between the time the manifest is complete and the plane is about to take off. For police and security authorities, if they have sufficient grounds to believe that this is a dangerous traveller who could put that aircraft in danger, or who would be heading to a part of the world to engage in terrorist activity, presuming they have the information that says they are a risk, having the information that they're about to get on an airplane is very useful.
If they have the legal authority, they can take the appropriate action to prevent that person from getting on the airplane. But first of all, they have to know: are they trying to get on an airplane? At the moment, we don't have that information. With Bill C-21, we will know if an individual is trying to get on an airplane, and then, with the other legal authorities in place, police or security officers would be able to take the appropriate action.
