Woodstock was the former home of the Oxford Regional Centre. Opened in 1906 as the Hospital for Epileptics, it was later renamed the Ontario Hospital in 1919. Originally on the west side of Highway 59, the hospital then expanded on the east side in the 1950s and transformed into a house for mentally disabled individuals. At its peak, the centre employed 1,500 people. It closed in 1996, and since then all buildings have been demolished except for part of the powerhouse, now the Brickhouse Brewpub - part of the Upper Thames Brewing Company, and the mess hall which has been converted into a community centre for Sally Creek. As well a carved insert with the words "Ontario Hospital" remains in the stone wall on the west side of Highway 59 north of Fairway Road. A polished black granite memorial to the institution sits at Dr. J. J. Williams Park on Lakeview Drive east of Highway 59.
