Exeter is a Canadian community in the municipality of South Huron, in the southern portion of Huron County, Ontario, located approximately 50 kilometres north of London. The community proclaims itself the "Home of the White Squirrel", owing to the presence of the unusually-coloured mammals. Exeter's mascot, "Willis The White Wonder" (Doug Westlake) can be seen at many community events throughout the year, including Canada Day celebrations, the Exeter Rodeo, and the Santa Claus Parade. Recently Exeter has opened a new Crabby Joe's Tab & Grill restaurant.
Exeter was first founded in the winter of 1832 by the Irish settlers James and Jane Willis and also Amanda. By 1853, Exeter had grown into a community of over 300 with the help of Isaac Carling bringing immigrants from the Exeter and Devon areas of England.The original Carling homestead, a designated historical landmark still stands on Huron St.W. It was on July 1, 1873, when the villages north and south of the Ausable River (Francistown and Exeter respectively) merged to form the Village of Exeter. Exeter eventually became a town of over 4,700 people. Paintings of some of Exeter's historical citizens, by the late artist Harry Burke, may be seen at the Exeter Legion Hall.
The local newspaper is the Exeter Times-Advocate, owned by Metroland Publishing. This paper publishes once-weekly, on Wednesdays.
