Mr. Speaker, I would like to present the following petition which has signatures from all across this nation. Whereas the majority of Canadians support the current legal definition of marriage as the voluntary union of a single male and a single female and whereas it is the duty of Parliament to ensure that marriage as it has always been known and legally affirmed in Canada be preserved and protected, therefore, the undersigned petition Parliament to use all possible legislative and administrative measures involving invoking section 33 of the charter, the notwithstanding clause, if necessary, to preserve and protect the current definition of marriage as between one man and one woman.
In the House of Commons on April 30th, 2003. See this statement in context.
