The Centre for Addiction and Mental Health (CAMH, pronounced KAM-aytch, French: Centre de toxicomanie et de santé mentale) is a psychiatric teaching hospital located in Toronto and ten community locations throughout the province of Ontario, Canada. It reports being the largest research facility in Canada for mental health and addictions. The hospital was formed in 1998 from the amalgamation of four separate institutions – the Queen Street Mental Health Centre, the Clarke Institute of Psychiatry, the Addiction Research Foundation, and the Donwood Institute. It is Canada's largest mental health teaching hospital, and the only stand-alone psychiatric emergency department in Ontario. CAMH has 90 distinct clinical services across inpatient, outpatient, day treatment, and partial hospitalization models. CAMH has been the site of major advancements in psychiatric research, including the discovery of the Dopamine receptor D2. Source: Wikipedia (en)
