The changes to the federal electoral district boundaries take effect for the 45th Canadian federal election, which will be the first general election called after April 22, 2024.[4][5] If the election had been called before the new electoral boundaries were established, that election would have occurred using the existing electoral district boundaries, which had been in effect since the 2015 federal election was called on August 4, 2015.[6][7]
Under the Electoral Boundaries Readjustment Act, to redistribute the electoral boundaries within each province, ten independent electoral boundary commissions will be established, one for each province. The commissions are composed of three members, one appointed by the chief justice of each province, and two members appointed by the speaker of the House of Commons.[9][10]Nunavut, the Northwest Territories and Yukon do not require commissions as each territory is allotted only a single member in the House of Commons, resulting in the entirety of each territory being a single electoral district.[1][11]
