Indigenous Etymology: The name Ontario originates from the Huron-Wendat or Iroquoian (Haudenosaunee) word Oniatarí:io, meaning "Lake of Shining Waters" or "Great Lake". It is an indigenous hydronym that predates both the Canadian province and the United States by centuries.

Legal Treaty Status: Governed by the 1909 Boundary Waters Treaty and the binational International Joint Commission (IJC). Neither national executive has unilateral authority under international law to rename or rezone shared boundary waters.
