The settlement began in 1829 after a dam was built on the Grand River to supply water for the Welland Canal. It was incorporated as a village in 1860 and as a town in 1900. The economy was shaped by milling, port activity, and later service industries. Today, it remains an unincorporated community within Haldimand County.
