Psychiatric Services

Various psychiatric services, described, below, are offered at the West Island HSSC.  

Please note that all persons must go through the One-Stop Access, with a referral from a family doctor. 

Intensive Follow-up in the Community

Intensive Follow-up is for people with severe mental disorder whose condition is unstable and fragile. The follow-up is very structured and the objective is to maintain the patient in the community. This service is intended for people who need treatment, rehabilitation and support. 

Outpatient Psychiatry Clinic  

The Outpatient Psychiatry Clinic provides psychiatric assessments and consultations. It also provides treatment for the most complex cases.   

Variable Support 

Variable Support is for people with severe mental disorders whose degree of mental disorder is generally not as severe as people requiring intensive follow-ups, but which does not exclude periods of great fragility. The clientele served has rehabilitation and support needs. 


There are 31 beds at the Lakeshore General Hospital to meet the hospitalization needs of adults whose health condition requires treatment 24 hours a day, 7 days a week.
