The Office québécois de la langue française (OQLF) is the Quebec government agency responsible for ensuring compliance with the Charter of the French Language (Bill 101) and promoting French usage. The OQLF oversees francization of businesses, commercial signage compliance, and use of French in public communications. Inspectors investigate complaints about language law violations, sometimes prompting media coverage that earned the agency the nickname 'language police.' The OQLF also provides terminology resources and supports French usage in technology and business. Bill 96 (2022) expanded the OQLF's powers. Municipal compliance with language laws falls within OQLF oversight.
