Inpatient Treatment Units

Trillium Health Partners is committed to delivering the highest quality of care in a safe therapeutic environment through its Inpatient Units at both our Credit Valley Hospital and Mississauga Hospital sites.  

The inpatient program is focused on the stabilization of symptoms and supports the recovery of the acutely ill client. The units are staffed by an inter-professional team that may include: psychiatrists, general practitioners, nurses, social workers, occupational therapists, peer support workers, and pharmacists. Our inter-professional team will offer you and your family an individualized treatment plan. This treatment plan will reflect each individual’s unique treatment needs. Group therapy is a part of the treatment plan offered Monday to Friday. 

At the Mississauga Hospital, we have a total of 46 Adult Inpatient beds. There are three units: Mental Health GB, Mental Health 1B, and Mental Health ICU. 

At the Credit Valley Hospital, we have a total of 19 Adult Inpatient beds on our 2D Mental Health Adult Inpatient Unit.
