About Me
Debbie Ernest
B.A., B.S.W., M.S.W., R.S.W
I am a Registered Social Worker, Psychotherapist, and Consultant with extensive training and more than 20 years of clinical experience working in mental health and addictions hospital-based care, the post-secondary education sector, and in private practice specializing in mental health and substance use issues - spanning individual, family, and group treatments.
I received my Master of Social Work degree from the University of Toronto, a Bachelor of Social Work from Toronto Metropolitan University (formerly Ryerson University), and a Bachelor of Arts from the University of Western Ontario.

My Approach
I am a highly-skilled, experienced, compassionate, committed and ethical therapist who provides evidence-based treatment interventions and high-quality care to my clients. I take a client-centered, trauma-informed approach to identify a client’s unique needs and collaborate on a plan of care to help them reach their therapeutic goals. I believe the foundation of good and effective therapy is a strong therapeutic alliance and the facilitation of safety and trust in the therapeutic work. I am known to have a warm and empathic interpersonal style and I tend to bring my sense of humour to the work that I do.
​

My Background
In addition to my work in private practice, I have an established career history working in the mental health and addictions and postsecondary education sectors as a therapist, clinical supervisor, and educator. I worked for 18 years at the Centre for Addiction and Mental Health (CAMH) as a Social Worker and individual and group therapist servicing clients with mental health and substance use issues in a variety of in- and out-patient settings. I provided therapy to youth experiencing a first episode of psychosis and provided support and therapy to their families; opioid-dependent individuals and clients seeking addiction medicine services; women with addictions; clients impacted by trauma; clients with anxiety and depression; those with emotion regulation difficulties; clients in crisis and dealing with suicidal thoughts; and clients with complex mental illness – specializing in clients with psychosis and schizophrenia and their families. I also have experience working with clients with concurrent mental health and substance use issues. As a member of the Cognitive Behaviour Therapy (CBT) Service of the Complex Mental Illness Program, I provided individual and group-based CBT for psychosis services to clients with complex mental illnesses.
​
During the final decade of my career at CAMH, I worked as an Advanced Practice Clinical Leader – during which time I provided therapy to clients and families, offered local, regional, and international training on a variety of mental health and addictions topics, and provided clinical supervision and professional practice leadership and consultation to interprofessional staff, teams, and students at the hospital.
​
After leaving the health care sector, I worked in post-secondary education in a leadership position within the Counselling and Accessibility department of a large post-secondary college setting where I provided counselling and crisis intervention services to youth and adult college students and supervised a team of personal counsellors who provide short-term counselling to students with a range of mental health and other personal issues. I also have experience working as a Counsellor in a Toronto law school providing therapy and mental health and wellness counselling to law students within a competitive and high-pressure academic environment.
