The 1977 ''Charter of the French Language'' established French as the official language of Quebec. Although more than 85 percent of French-speaking Canadians live in Quebec, there are substantial Francophone populations in New Brunswick, Alberta, and Manitoba; Ontario has the largest French-speaking population outside Quebec. New Brunswick, the only officially bilingual province, has a French-speaking Acadian minority constituting 33 percent of the population. There are also clusters of Acadians in southwestern Nova Scotia, on Cape Breton Island, and through central and western Prince Edward Island.
