In 2019, the Government of Alberta rescinded Pétain's name from the Alberta side of the border. On June 29, 2022, the Government of British Columbia also rescinded the name, rendering the mountain officially nameless. As of July 2022, neither of the provinces in which the mountain sits have decided on a new name.
