 Geriatric Mental Health Services

We provide assessments, treatment and management for clients who reside in Mississauga and the southwest Etobicoke area. This includes consultation and education for clients, families and caregivers. Coordination with family physicians, family members and other health care providers and community partners is an essential component of our service.

Out-patient and Outreach
This program provides comprehensive psychiatric assessments and psychosocial intervention for seniors who live in south Toronto or Mississauga and who are at risk of requiring admission to hospital for psychiatric treatment. Individuals under 65 who are diagnosed with an early onset mental health illness may also be eligible for the program.
Out-patient and outreach services can be accessed through the out-patient clinic, or through the outreach program which is provided in the individual’s place of residence (private home, long term care home or retirement home).
The service also provides consultation and education for clients, families and other professionals involved in the care of the individual. Services are provided by geriatric psychiatrists, a nurse practitioner, nurses, social workers, and occupational therapists
