About Us

GreeneStone is a private, residential addiction treatment centre in beautiful, serene Muskoka. With an established track record as the best opioid and addiction clinic in Ontario, residents come to us from across Canada.

If you or a loved one needs alcohol rehab or requires help with overcoming drug dependency, our team is waiting for you to make the first step and ask for help.

GreeneStone was founded in the summer of 2011. Previously a resort, the site was converted into an inpatient treatment facility keeping all 43 acres worth of property and resort amenities. Our addiction clinic is CARF™ (Commission on Accreditation of Rehabilitation Facilities) accredited for both its detox and treatment programs.


  • Unique: Environment is completely out of typical environment which allows one to disconnect and focus on themselves. Views of Muskoka Lakes provide Bluespace and surrounding forests provide Greenspace which is crucial to mental health and overall well-being. All rooms are private, equipped with Queen or King size beds only, tubs or Jacuzzi’s which is great for pain management. Full medical detox onsite allows an easier transition to gain stability. A smaller community creates a quieter more settled community and gives more time for patients.
  • Expert Residential Team: GreeneStone’s staff members are professionals who are passionate about helping others and dedicated to keeping up with change. Struggling with alcohol abuse, a drug dependency, PTSD or any other form of addiction makes it hard for residents to be away from their homes and their loved ones. Our trained and experienced team works together to ensure that residents are comfortable and feel safe during their stay. This includes staff from housekeeping, maintenance, kitchen, nursing, medical, clinical, admissions, and administrative departments.
  • Inpatient Care: At GreeneStone, the duration of stay for each resident is flexible and based upon individual needs. Our inpatient services include 24×7 nursing care and Nurse Practitioners. Medical Director support provided by physicians. We have a team of three clinical therapists that specialize in addictions and concurrent disorders, two trauma therapists specializing with PTSD, severe trauma, anger management, and TIR therapy. Our physical health team includes a massage therapist, a personal trainer and yoga instructor.
  • Stellar Reputation: Our reputation speaks for itself. Here is one example of a resident’s post-treatment comment: “GreeneStone Muskoka changed my life in the best possible way. I’m so grateful for the time I got to spend at GreeneStone, as it was the foundation for the life I have today. GreeneStone saved and changed my life, I will forever be grateful.”
