Saltford is a small unincorporated community in Ontario, Canada located at the intersection of Highway 21 and Saltford Road, on the east bank of the Maitland River in the township of Ashfield-Colborne-Wawanosh just east of Goderich. In early 1866, local entrepreneur Samuel Platt discovered the presence of brine while drilling for oil in the community. He subsequently developed a salt extraction business, using an evaporation process.
