Federal electoral district names updated across multiple provinces, including three Ontario ridings

An Act to change the names of certain electoral districts, 2026

Plain-language summary · AI-assisted · not legal advice

Parliament has renamed a number of federal electoral districts across Canada, with three Ontario ridings affected: "Brantford—Brant South—Six Nations" becomes "Brantford—Brant South," "New Tecumseth—Gwillimbury" becomes "York—South Simcoe," and "York Centre" becomes "North York." Additional name changes apply to ridings in Newfoundland and Labrador, Nova Scotia, New Brunswick, Saskatchewan, British Columbia, and Quebec. These are administrative renaming changes only — the geographic boundaries of the districts are not altered by this act. Organizations, government bodies, and businesses that reference federal electoral district names in forms, databases, correspondence, or compliance records should update those references to reflect the new names.

Who this affects: government agencies and registries using electoral district names · businesses and organizations that reference ridings in compliance or administrative records · election administrators and returning officers · political parties and candidates in renamed ridings
