The road to recovery is just
one step away

The Queen Street Treatment Clinic provides a Methadone Maintenance program to help people overcome their addiction to opiates. Although we are dedicated to encouraging abstinence from all mood altering drugs, a risk reduction model is at the core of our program.

Our highly trained staff and licensed Doctors specialize in Addiction Medicine, Psychiatry, HIV and Hepatitis C Treatment.

We encourage and support clients by offering a combination of counseling and Methadone treatment. Counseling is not mandatory, but when combined the outcome is far more effective.

We look forward to working with you during your recovery process and will gladly provide you with the resources that you may need to accomplish your goals of sobriety.



The Canadian Addiction Treatment Centres and affiliated brands are committed to eliminating barriers at all of our clinics and pharmacies for employees, patients and visitors with disabilities and improving accessibility in a manner that respects their dignity, independence and integration.
