Palmerston is an unincorporated community located at the south end of the town of Minto in northern part of Wellington County in southern Ontario, Canada.HistoryPalmerston was a key division point for the Grand Trunk and later the Canadian National Railway in Southwestern Ontario with 65 subdivisions; Owen Sound, Kincardine, Durham, Fergus, Guelph Junction and Stratford. In its original concept the railroad was to run from Guelph to Southampton, Ontario and would not have gone through Palmerston. Listowel needed to be linked to the railroad and it was decided to bend the route toward Listowel. It was also decided that a yard with maintenance shops would be needed. The mainline under Canadian National ownership became part of the Fergus, Owen Sound and Southampton Subdivisions. Passenger service ceased in 1971. The subdivisions were abandoned starting with Fergus to Palmerston August 1983, Harriston Jct. to Port Elgin and Southampton in 1988, Guelph to Fergus 1988 and Palmerston to Harriston 1995. And all rail service terminated in 1996 with CN abandoning the line from Stratford to Harriston.When the railroad decided to build a junction and maintenance sheds between Guelph, Harriston and Listowel, this also included a station. One of the active supporters of the railroad was John McDermott, Reeve of Wallace and, because of this support, the railways decided to let McDermot name the station. He named it Palmerston in 1870 in honour of Henry John Temple, the future third Viscount Palmerston. As soon as the railroad decided where it would build, people started buying property around the area for businesses and homes.
