The U.S. already collects exit information in a systematic fashion without physical control. After the last incident in Times Square, law enforcement was able to identify a potential suspect fairly quickly. That information was shared with U.S. Customs and Border Protection, and they were able to arrest somebody who was trying to board a plane to get out of the country. I think that's an example of how valuable that information is.
Even domestically, we've had instances of parents phoning the police or CBSA because they feared that their kids were about to take a plane to Turkey or Syria. Our ability to act and prevent such departures is very limited, unless we have very specific information about where and when the departure is to occur. With this, if the bill gets royal assent, we will have the ability to do a query and see if we have somebody scheduled to depart on a particular flight.
