Cayuga is an unincorporated community and county seat of Haldimand County, Ontario, Canada located at the intersection of Highway 3 and Munsee Street and along the Grand River. Cayuga is about a 20-minute drive from Lake Erie and 30 minutes south of Hamilton and 115 minutes south of Toronto and consequently it has some cottages and recreational properties in the area. In the past there was some light industry. It has the local district detachment for the Ontario Provincial Police. It is also uniquely located among larger communities on both the American and Canadian sides of the border boasting television reception from Toronto, Buffalo, New York, Hamilton, Kitchener and Erie, Pennsylvania.
Cayuga was incorporated as a village in 1859 and became the county seat for Haldimand County because of its central location. It is named after the Cayuga, one of the Six Nations of the Grand River Natives who were awarded land in the area for siding with the British in the American Revolution. As the county seat, it is the location of the Court House, jail and a museum. In the late 18th century and early 19th century, public hangings were held in the courtyard and the prisoners buried on site. The Highway 3 bridge over the Grand River (Cayuga Bridge) is a very well recognized bridge over the Grand River and is commonly used as a symbol of Haldimand County and the Grand River. The same bridge was also used in a movie that commemorated Terry Fox. Sadly, this bridge will no longer be a symbol of the Grand River and Haldimand County as it was replaced in the summer of 2014 with a "modern" concrete bridge.
