Cape Vincent Town Hall is located at 1964 Route 12E, Cape Vincent NY 13618.
The town of Cape Vincent is located where Lake Ontario and the St. Lawrence River meet, in the northwestern corner of Jefferson County, New York. Inland it is bounded by the towns of Clayton, to the east, and Lyme, to the south. The long shoreline is the primary natural attraction in the town. The land, which is low and rolling, rises gradually to the southeast. It is generally open, with pasture, cultivated fields and abandoned cropland, interspersed with wetlands, mixed hardwood forest and stands of conifers.
Development in the town of Cape Vincent is concentrated in the village of Cape Vincent, the hamlets of Millens Bay, Rosiere and St. Lawrence, and in a narrow strip along the shoreline where State Route 12E parallels the river. Most of this shoreline development consists of summer homes. During the summer season, summer residents double the population of the town and contribute significantly to the local economy. The Broadway Historic District and fifteen of the individual components are located in the village of Cape Vincent, and the remaining eleven individual components are located in hamlets and throughout the rural areas of the town.
The town is linked to population centers to the south by State Route 12E which turns east in the center of the village of Cape Vincent and follows the river. The village is also the point of departure for the ferry to Wolfe Island, the only remaining St. Lawrence River ferry between the United States and Canada.
