Assertive Community Treatment (ACT) Chatham


If you are experiencing a mental health emergency please contact Community Crisis Services at (519) 973-4435 or go to your nearest Emergency Department.


Assertive Community Treatment (ACT) is a community-based model of care for individuals who have severe and persistent mental illness. It reaches out to people assertively where and when they need help directly in their home, at the ACT office and in the community. It ensures a response for people who are in crisis, no matter what day of the week.


Two ACT teams serve the Windsor-Essex community and support up to 200 individuals, one ACT team serves Chatham-Kent and Walpole Island and can support up to 88 individuals. Each client is assigned a primary care provider responsible for managing their care and services are delivered as frequently and as long as the client requires them. ACT brings a multidisciplinary team of healthcare professionals together to provide highly integrated and individualized services for their clients, including nurses, social workers, occupational therapists, therapeutic recreation specialists, vocational therapists and psychiatrists.


Referrals to the teams are made directly to ACT and are reviewed by an access committee to determine if criteria are met. ACT gives people a single point of access: one door to comprehensive treatment, rehabilitation and support. It is designed for individuals who have complex and long-term psychiatric illnesses such as schizophrenia and bi-polar disorder. ACT clients have severe symptoms not effectively managed by other available treatments, or they have not been engaged in those treatments. ACT clients require support in meeting basic needs, performing activities of daily living and managing other illnesses, such as diabetes or high blood pressure. Model of service is ACT Provincial standards.
