The electoral district existed over three distinct periods: Pontiac lost territory to Argenteuil—La Petite-Nation and gained territory from Hull—Aylmer and Gatineau during the 2012 electoral redistribution.

Following the 2022 Canadian federal electoral redistribution, the riding will largely be replaced by Pontiac—Kitigan Zibi.

It loses Val-des-Monts to Argenteuil—La Petite-Nation; loses that part of the City of Gatineau west of Montée Paiement to the riding of Gatineau; and gains the rest of the Plateau neighbourhood from Hull—Aylmer.

The electoral district includes: The neighbouring ridings are Abitibi—Témiscamingue, Abitibi—Baie-James—Nunavik—Eeyou, Saint-Maurice—Champlain, Laurentides—Labelle, Argenteuil—La Petite-Nation, Hull—Aylmer and Gatineau (in Quebec) and Glengarry—Prescott—Russell, Ottawa—Orléans, Ottawa West—Nepean, Carleton—Mississippi Mills, and Renfrew—Nipissing—Pembroke (in Ontario).
