Stanstead is a town in the Memphrémagog Regional County Municipality in the Estrie region of Quebec, located on the Canada-United States border across from Derby Line, Vermont.The Town of Stanstead was created in 1995 by the merger of the former towns of Stanstead Plain, Rock Island and Beebe (formerly Beebe Plain). It is not to be confused with the township of Stanstead, which is nearby although not directly adjacent (the municipality of Ogden lies in between).
