Ontario County is a county in the U.S. state of New York. As of the 2010 census, the population was 107,931. The county seat is Canandaigua.
Ontario County is part of the Rochester, NY Metropolitan Statistical Area.
In 2006, Progressive Farmer rated Ontario County as the "Best Place to Live" in the U.S., for its "great schools, low crime, excellent health care" and its proximity to Rochester.
This area was long controlled by the Seneca people, one of the Five Nations of the Iroquois Confederacy, or Haudenosaunee. They were forced to cede most of their land to the United States after the American Revolutionary War.
When the English established counties in New York Province in 1683, they designated Albany County as including all the northern part of New York State, the present State of Vermont, and, in theory, extending westward to the Pacific Ocean. On July 3, 1766 Cumberland County was organized, and on March 16, 1770 Gloucester County was founded, both containing territory now included in the state of Vermont. The English claims were their assertion; the Five and then Six Nations of the Iroquois occupied and controlled most of the territory in central and western New York until after the Revolutionary War.
