Located in south-central Ontario, Canada. Orangeville, the County seat, is located about 120 km north-west of Toronto. Dufferin County has an area of 1,442 km2 (557 square miles) and a population of 40,997 (1994). There are three towns: Mono, Orangeville and Shelburne, and five rural townships: Amaranth, East Garafraxa, East Luther Grand Valley, Melancthon, and Mulmur. Over half of the County's population lives in Orangeville. Named after Lord Dufferin, who was Governor-General of Canada from 1872 to 1878, the county was formed in 1881 from parts of the Counties of Grey, Simcoe, and Wellington. The original County consisted of the Towns of Orangeville and Shelburne and five townships: Mono, Mulmur, Melancthon, Amaranth, and East Garafraxa. (The Township of East Luther was transferred from Wellington County in 1883.) Because of geography and economy (the upper Grand River watershed), Dufferin and Wellington Counties remain strongly tied in many ways. Organizations with names prefixed with "Upper Grand" and "Grand Valley" are found in both counties.

Wellington County became a corporation sole on December 30, 1853 and held its first council meeting on January 23, 1854. The municipality was named after Arthur Wellesley, the first Duke of Wellington. Parts of Wellington were ceded during the 1880s to the County of Dufferin, which was then emerging as a settled area of Ontario. Although this occurred over 100 years ago, the two counties are still closely tied, and even today Wellington and Dufferin share a number of organizations and institutions. Located to the west of Toronto, north of Hamilton and east of Kitchener/Waterloo, Wellington County is part of Canada's Technology Triangle. Major communities in the county include the City of Guelph, the towns of Fergus, Elora, Arthur, Harriston, Palmerston and Mount Forest and the smaller communities of Rockwood, Erin, Alma and Clifford, among others. Wellington County contains rich farmland and diverse scenic beauty. Much of it is drained by the Eramosa, Grand, Speed and Irvine Rivers in the south, and the Saugeen River in the north. It is predominantly a rural, agricultural area with the City of Guelph as its main urban centre. Guelph is located in the south part of the County. The population of the County including the City of Guelph is 170,000. The rural population is 69,348 living on a land mass of some 245,671 hectares of which just under 20% is forested.
