Mansonville is a village in the Potton township of the Eastern Townships of Quebec, Canada, in Memphrémagog Regional County Municipality of the Estrie region, across the Canada–United States border from North Troy, Vermont. Now Mansonville is the business centre and the seat of Municipalite du canton de Potton. Formerly a sleepy community, Mansonville has experienced some growth and prosperity because of its proximity to Owl's Head ski resort.
