This paper suggests a novel way by which “triple-E”-type Senate reform could be used as the basis for introducing the proportional representation of parties into the Canadian electoral system. The proposal involves an extension and rationalization of the existing Senate-division structure, the direct election of the Senators of each province or territory from party lists in accordance with the principle of proportional representation, and the effective folding of the reconstituted Senate into the House of Commons by allowing members of the former to sit in the latter and requiring that the members of both meet and decide questions together. These reforms would solve many of the representation problems of the existing first-past-the-post electoral system without unduly compromising its benefits. In addition, they could be accomplished via the general procedure for amending the Constitution of Canada, which has the political advantage of not requiring the unanimous consent of the provincial legislatures.
