Mr. Speaker, security certificates are one of the measures used to remove non-Canadians from this country when they pose a threat to national security. It is an exceptional measure.
Since 1991 some 27 security certificates have been issued. In fact, the security certificate, as a tool to protect the national security of Canadians, has been reviewed by the highest level, the Supreme Court of Canada. It has been found to be constitutional in terms of striking the right balance between national security and human rights.
