The Office of Francophone Affairs (French: Office des affaires francophones) in the Canadian province of Ontario is responsible for the provision of government services to Franco-Ontarian citizens and communities.
Under the province's French Language Services Act, the provincial government provides French language services if a community or region's francophone population exceeds 5,000 or 10 percent of the community's total population. There are 25 areas of the province so designated. The office also has a role in the governance of Ontario's francophone public television network, TFO, as well as francophone school boards and other government offices, and acts as a liaison office between the government and other francophone cultural agencies and social services.
The Minister responsible for Francophone Affairs in the Executive Council of Ontario (or provincial cabinet) is Marie-France Lalonde. Past ministers included Bernard Grandmaître, Charles Beer, Gilles Pouliot, Noble Villeneuve and John Baird.
