"Across all facility types, half of all clients who received inpatient mental health treatment services on April 29, 2016, were involuntarily admitted for care: 38 percent of clients were admitted with an involuntary non-forensic (non-criminal) legal status and 15 percent were admitted with an involuntary forensic (criminal) legal status.
Involuntary admissions were highest (91 percent) for clients who received inpatient mental health treatment services in RTCs for children and lowest (19 percent) for clients who received inpatient mental health treatment services in another type of residential treatment facility."
