Mr. Miller, the Canadian law on this point is very clear.
We do not have a wall that is a physical barrier to the border. When someone steps across that border in an irregular fashion, they do not get a free ticket to Canada. They are arrested. They are apprehended by the RCMP. They are fingerprinted. All of their biographical and biometric information is taken. In terms of screening, that is done against the databases we have in Canada, and also databases elsewhere around the world. Is there any immigration flag? Is there any criminal flag? Is there any terrorist issue that can be raised?
