Mr. Speaker, the hon. gentleman needs to understand the rules. In fact, when people cross the border inconsistently with the rules, they are arrested and questioned. They are identified, both biographically and biometrically, and their identity is checked against every Canadian and U.S. database for any immigration, criminal, or security flags. Then they are required, in fact, to prove the necessity for protection in Canada. If they cannot prove that, their admissibility is denied, and they are removed from the country.
