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.
History of French
During the 17th and 18th centuries, the French language established itself permanently in the Americas. There is an academic debate about how fluent in French the colonists of New France were. While less than 15% of colonists (25% of the women – chiefly "filles du roi" – and 5% of the men) were from the region of Paris and presumably spoke French, most of the rest came from north-western and western regions of France where regular French was not the primary native language. It is not clearly known how many among those colonists understood French as a second language, and how many among them – who, in overwhelming majority, natively spoke an oïl language – could understand, and be understood by, those who speak French thanks to interlinguistic similarity. In any case, a linguistic unification of all the groups coming from France happened (either in France, on the ships, or in Canada) such that, according to many sources, the then "Canadiens" were all speaking French (King's French) natively by the end of the 17th century, well before the unification was complete in France. Canada's reputation was to speak as good French as Paris did. Today, French is the language of about 10 million people (not counting French-based creoles, which are also spoken by about 10 million people) in the Americas.
