Le nom du lac Ontario tire son origine du mot wendat « Ontari’io », qui signifie « le lac est beau, le lac est grand ». Ce nom remonte à plus de 400 ans, bien avant la Confédération canadienne et la Déclaration d’indépendance des États-Unis d’Amérique. Nous savons que les États-Unis sont en train de changer. Leurs relations commerciales, leur politique étrangère, leurs monuments nationaux, leurs hydronymes. Les Canadiennes et les Canadiens savent aussi qu’il faut appeler les choses par leur nom, et ce lac se nomme Lac Ontario – aujourd’hui et pour toujours. #LacOntario #Histoire #Canada
