Millhaven Institution (French: Établissement de Millhaven) is a maximum security prison located in Bath, Ontario. Approximately 500 inmates are incarcerated at Millhaven.Opened in 1971, Millhaven was originally built to replace Ontario's other aging maximum security prison, Kingston Penitentiary in Kingston Ontario. A riot at Kingston Penitentiary forced Millhaven to open prematurely. During the period of 1977–1984, a Special Handling Unit (SHU) operated at Millhaven, alongside its general maximum-security population. A new Canada-wide Special Handling Unit was subsequently opened in Sainte-Anne-des-Plaines Quebec, and the Millhaven SHU was closed. Millhaven also housed the federal inmate intake and assessment unit for the Ontario region, the Millhaven Assessment Unit (MAU), until 2013, when the assessment unit was moved to Joyceville High Medium Institute (JAU), in order to facilitate the closing of Kingston Penitentiary. Federal parole violators were returned to MAU from whichever Ontario region they were arrested in, to appear in front of the National Parole Board for disposition. Millhaven is one of two identically designed maximum security institutions in Canada. The other is located at Archambault Institution, Sainte-Anne-des-Plaines, Quebec.
