Assertive Community Treatment (ACT) Programs

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



Hôtel-Dieu Grace Healthcare’s (HDGH) Assertive Community Treatment (ACT) program is a community-based, recovery model of care for individuals who have severe and persistent mental illness. ACT assertively reaches out to clients where and when they need help – directly in your home and in your community.

A total of three ACT teams provide care throughout Windsor-Essex (2) and Chatham-Kent (1) Counties.

ACT brings an inter-professional team of healthcare workers together, including psychiatrists, social workers, nurses, occupational therapists, therapeutic recreation and vocational rehab therapists, to provide you with highly integrated and individualized services. ACT gives you a single point of access – one door to comprehensive treatment, rehabilitation, and support, at any time or day of the week.


ACT works with you as an active participant in your care with the goal of promoting independence and stability, having better control of mental health symptoms, decreasing the likelihood of hospitalization, and achieving an overall improved quality of life.


If you are interested in ACT, you are encouraged to discuss it with your current treatment team or physician. Eligibility for receiving ACT services is determined through collaboration with you, ACT staff, the referral source, and other mental healthcare providers.


ACT services at HDGH are funded by the Ministry of Health and Long-Term Care. Services are provided at no cost to you upon presentation of a valid OHIP card.

Families’ and Friends’ Role in Promoting Safety


Family members and friends play an important role in patient safety.  Encouraging
attendance of appointments, taking medications and asking to be involved in
understanding and facilitating treatment plans is recommended among family
members and friends.  If family members and friends have serious concerns
about a loved one’s safety and well-being please utilize emergency (911) or
crisis hotline (519-973-4435) services or locations (nearest emergency room or
crisis centre) as needed.  You are always allowed to provide us with
information however we may not be able to relay information/feedback to you
directly.  For any important messages the hospital contact information is
provided on this website under the Contacts link.

Thank you for your role in promoting safety.
