Introduction: Readjusting Federal Electoral Boundaries
Section 51(1) of the Constitution Act, 1867 requires that the number of MPs per province be recalculated after each decennial census and, consequently, that the electoral boundaries of ridings within each province be readjusted every ten years. Parliament redrew electoral boundaries directly from the 1870s to the 1950s. But since 1964, the Electoral Boundaries Readjustment Act provides that independent Federal Electoral Boundaries Commissions, one for each province, decide where and how to readjust electoral boundaries in a non-partisan manner. Each commission is chaired by a judge and consists of two other members appointed by the Speaker of the House of Commons. The commissions release an initial proposal, hold public hearings throughout the province on that proposal, and then release a preliminary report based on what they learned from anyone who commented either for or against the proposal. MPs then study the preliminary reports and make recommendations on changing either the names or boundaries of ridings, which the commissions must consider but may (and usually do) reject in their final reports. Those final reports then become the Representation Order, a piece of secondary legislation that the Governor-in-Council promulgates under the Electoral Boundaries Readjustment Act. Those Representation Orders enter into force for a dissolution of parliament seven months later.
