Accredited for Excellence in Client Care ​

Our treatment centres are accredited with CARF: the gold standard of excellence in inpatient (sometimes called “rehab” or “residential”) addiction treatment. 

This industry-leading designation is proof that we adhere to the highest bar of operational and clinical quality. We hold ourselves accountable to referents and clients in ensuring the best possible results for people in our care. 

Help your clients choose the right treatment option.

As an Interventionist, helping clients and their loved ones choose the right treatment program, while helping them understand their roles in the process, can be a difficult task. There are many factors to consider in best meeting their needs, and your needs as a partner in their journey.

As Canada’s largest accredited treatment provider for substance use disorder and addictive behaviours, Canadian Addiction Treatment Centres (CATC) strives to be an effective partner for Interventionists. We support you and your clients every step of the way, from pre-admission and medical detox through to aftercare, while keeping the flow of information coming to you clearly and consistently so that you’re never left in the dark on their progress. We also work with you to make the admission process as quick and efficient as possible.

Best-in-Class Treatment

Our compassionate and highly-skilled teams at our 3 CARF-accredited inpatient addiction treatment centres provide you with a streamlined and reliable point of contact, working hand-in-hand with you and your clients to create personalized treatment plans that meet their every need. During their stay at any one of our beautiful, home-like centres, clients participate in individual counselling, psychoeducational groups, process groups, recovery coaching and various wellness programs.

Throughout their stay, we keep you actively engaged, so you can continue your work, knowing you’re getting full insight into their progress.

GreeneStone Centre for Recovery

Helping people recover from addiction for decades

We work hard to build and sustain Interventionists’ trust by going above and beyond to help their clients work towards their recovery goals. Our commitment to providing exceptional quality care is evidenced by our CARF-accredited status: the industry-leading gold standard for inpatient addiction treatment. CATC has been helping people recover from substance use disorder since the mid 1990s.

We operate 3 accredited inpatient addiction treatment and detox centres in Ontario, over 70 rapid access outpatient clinics, and a fully online intensive outpatient program—all staffed by an interconnected clinical team that works together to provide end-to-end case management and continuity of care. We use evidence-based medical modalities to provide personalized treatment plans for your clients, taking them through a comprehensive evidence-based program delivered by an interdisciplinary care team of nurses, therapists, counsellors and physicians.

One client at a time

Your top priority is our top priority: supporting your clients’ work towards their recovery goals

No more phone tag or unanswered emails. A member of our team will be your dedicated point of contact, providing regular and reliable updates on your clients’ progress.

We work with you to create a continuity of care plan that supports your clients’ efforts, bolstered by our peer alumni support and virtual aftercare programs.

We work with you and your clients to plan and roll out a full recovery plan, including any additional community or health services they may need during or after treatment.

From admission to discharge, we work with you to build a customized treatment plan to support the best possible outcomes for your client.

We work with you to streamline each intake as much as possible, so as to make the most of each window of opportunity to begin treatment.

Waiting weeks, or even months, to start an inpatient addiction treatment program is never in a client’s best interest. Get them the help they need, more easily.
