The name 'Lake Ontario' originates from the Wendat word 'Ontari’io', meaning 'the lake is beautiful, the lake is great', and this name has been used for over 400 years.

PM Carney posted #Canada to continue to call it Lake #Ontario. It was called Lake Ontario, a Wendat word, before Confederation in 1867, even before the province was created. It was Ontario before 1776.

Carney on Lake Ontario: “The name of Lake Ontario derives from the Wendat word « Ontari’io », which means « the lake is beautiful, the lake is great ». This name dates back more than 400 yers, well before the Canadian Confederation and the Declaration of Independence of the United States of America. We know that the US is changing...Canadian women and men also know that things must be called by their name, and this lake is called Lake Ontario – today and forever.”
