Franco-Ontarian
There are more than 600,000 francophones residing in Ontario. According to the 2016 Canadian census, there were 550,600 people living in Ontario who declared French their first official language spoken, 490,715 people who declared French their mother tongue, and 277,045 Ontarians who declared French as the language they speak most often at home. Over 1.4 million Ontarians reported themselves as bilingual, and 1.3 million Ontarians reported partial or full French ethnic origins. French-speaking Ontarians constitute the largest French-speaking community in Canada outside Quebec, as well as the largest minority language group within Ontario, and French is the fourth most common ethnic background in the province after English, Scottish and Irish.
Languages of the United States
French, the fourth-most-common language (when all varieties of Chinese are combined and separate yet related languages such as Haitian Creole are counted as French), is spoken mainly by the Louisiana Creole, native French, Cajun, Haitian, and French-Canadian populations. It is widely spoken in Maine, New Hampshire, Vermont, and in Louisiana, with notable Francophone enclaves in St. Clair County, Michigan, many rural areas of the Upper Peninsula of Michigan and the northern San Francisco Bay area. 
Three varieties of French developed within what is now the United States in colonial times: Louisiana French, Missouri French, and New England French (essentially a variant of Canadian French). French is the second language in the states of Louisiana (where the French dialect of Cajun predominates) and Maine. The largest French-speaking communities in the United States reside in Northeast Maine; Hollywood and Miami, Florida; New York City; certain areas of rural Louisiana; and small minorities in Vermont and New Hampshire. Many of the New England communities are connected to the dialect found across the border in Quebec or New Brunswick. More than 13 million Americans possess primary French heritage, but only 2 million speak French or a French Creole language at home.
