Millhaven institution is a maximum security prison in Canada. Opened in 1971, Millhaven was originally built to replace Ontario's other maximum security prison, Kingston Penitentiary. A riot at Kingston Penitentiary forced Millhaven to open early. Millhaven houses the federal inmate intake and assessment unit for the Ontario region. (Millhaven Assessment Unit or MAU). Federal parole violators are returned to MAU (from whatever Ontario region they were arrested) to appear in front of the National Parole Board for disposition.
Millhaven consists of three main living units, a segregation unit and a hospital wing. There are approximately 120 men per unit. The units have two levels. Cells are double sided and have hydraulically locking metal doors housing two inmates in each cell. The cells are designated by alphanumeric code (example; A1, B3).
" Cells " at MillhavenMain living units are designated by Alpha codes:
A Unit = Federal Intake and Assessment Unit - Ontario region (MAU) (ranges B, C, & D)
E Unit = Federal Intake and Assessment Unit - Ontario region (MAU) (and institutional workers) (ranges F, G, & H)
I Unit = Administrative Segregation/Special Needs
J Unit = maximum security unit (MSU) (cells K, L & M)
N Area = Main intersection and security control hub
MAU (Millhaven Assessment Unit) houses inmates recently sentenced to federal time, in the Ontario region. They are assessed and placed in other prisons according to security needs. MAU is classified as integrated (housing convicts serving time on all types of charges).
MSU (J unit) houses habitually violent offenders, and is non-integrated (no sex offenders, informants or incompatibles). Many inmates with life sentences are also housed in MSU. It is considered a "gladiator school", and convicts who serve time there are revered in the criminal subculture.
On September 30, 2013 Kingston penitentiary was closed. Many maximum security inmates that were housed there were transferred to Millhaven. A new 96 bed facility was constructed within the Millhaven compound, to house inmates from the Kingston Pen closure.
