# Wentworth County, Ontario

Wentworth County, area 269,057 acres (1,089 km$^2$), is a historic county in the Canadian province of Ontario.
It was created in 1816 as part of the Gore District (1816-1849) in what was then Upper Canada and later Canada West (1841-1867). It was named in honour of Sir John Wentworth, the last royal governor of colonial New Hampshire, lieutenant-governor of Nova Scotia (1792 to 1808) and an intimate friend of William Jarvis, the first provincial secretary of Upper Canada. The county originally consisted of seven townships that formerly belonged to Haldimand, Lincoln and York Counties.
Between 1850 and 1854, Wentworth County and Halton County were briefly joined for government purposes as the United Counties of Wentworth and Halton although for administrative purposes, they remained distinct.
In 1973, Wentworth County was replaced by the Regional Municipality of Hamilton–Wentworth. In 2001, the Regional Municipality and its six constituent municipalities were amalgamated as the "megacity" of Hamilton.
