The Full Record
The Naming History of Lake Ontario, and the American Habit of Renaming the Map
HOMES — Huron, Ontario, Michigan, Erie, Superior — is the standard English-language mnemonic for the five Great Lakes. Its origin is not securely documented; it circulates through classroom practice rather than through any traceable first publication. The lake names themselves are a mixture of Indigenous, French and English coinages, and several of them were unsettled for the better part of a century after Europeans first charted the basin. Lake Ontario is the clearest case.
What Lake Ontario has been called
Samuel de Champlain’s 1632 map of New France labels the lake Lac de St. Louis; the cartographer Nicolas Sanson used the same name as late as 1656. In 1660 the Jesuit historian Francis Creuxius (François Du Creux) recorded Lacus Ontarius, the earliest widely cited appearance of the modern name. The Relation des Jésuites for 1662–63 gives “Lac Ontario ou des Iroquois,” with the variant Ondiara set in smaller type. A French military engineer’s map of 1712 names it Lac Frontenac, after Louis de Buade, Comte de Frontenac, governor general of New France. The Mohawk name Katarokwi was in parallel use and appears in French colonial sources as Cataraqui. The form “Ontario” had become the standard label on French maps by the early eighteenth century.
The etymology
Ontario derives from the Wendat (Huron) Ontarí’io. It is most often translated as “great lake,” though other renderings, including “beautiful lake” and “lake of shining waters,” appear in the literature. The province of Ontario, created in 1867, takes its name from the lake rather than the reverse.
Renaming in the United States: a partial ledger
New Amsterdam was surrendered to an English force on September 8, 1664 and renamed New York for the Duke of York. A Dutch squadron retook the city in 1673 and renamed it New Orange; the Treaty of Westminster returned it to English control and to the name New York in 1674. Hot Springs, New Mexico, adopted the name Truth or Consequences on March 31, 1950, after the radio programme of that name offered to broadcast its tenth-anniversary episode from the first town to do so; residents have voted to retain the name since. Cape Canaveral, Florida, was renamed Cape Kennedy following an announcement by President Lyndon Johnson on November 28, 1963; after opposition within Florida, the state legislature moved to restore the original, and the United States Board on Geographic Names recognised the return to Cape Canaveral on October 9, 1973. The NASA installation on Merritt Island retains the name John F. Kennedy Space Center.
Mount McKinley, so called after a prospector’s 1896 proposal and made official in 1917, was renamed Denali by Secretarial Order in 2015 after a campaign begun by the State of Alaska in 1975. Executive Order 14172, “Restoring Names That Honor American Greatness,” signed January 20, 2025, directed the restoration of the name Mount McKinley and the renaming of the Gulf of Mexico as the Gulf of America; the Secretary of the Interior issued the implementing directives on February 7 and February 14, 2025. Denali National Park and Preserve retains its name.
