Addiction medicine doctors in downtown Toronto
If you're looking for a doctor for opioid or alcohol use disorder in downtown Toronto, our physicians see patients by appointment for assessment and treatment at 55 Dundas St E.
What Addiction Medicine Doctors Do
Addiction medicine is the part of medical care that treats substance use disorders, such as opioid use disorder and alcohol use disorder. For opioid use disorder, treatment usually means opioid agonist treatment (OAT): a long-acting medication, prescribed and monitored by a physician, that prevents withdrawal and reduces cravings. For alcohol use disorder, treatment can include medication to reduce cravings and help with managing withdrawal safely. Neither is a cure, and both work alongside ongoing medical care and support.
Not every family doctor provides OAT. It generally requires a physician with training and comfort in addiction medicine, which is why people often search specifically for an addiction doctor rather than a general practitioner. Finding the right prescriber matters, because starting and adjusting treatment safely needs a doctor who does this regularly.
Addiction Medicine Doctors at Our Downtown Toronto Clinic
Our physicians see patients at 55 Dundas St E in downtown Toronto for assessment and ongoing treatment. Appointments are booked in advance, so you will not be seeing a different doctor at random each time — you can build a treatment relationship with a physician who knows your history and can adjust your plan as needed. The clinic is a two-minute walk from Dundas Station on Line 1, and there is elevator access if you need it.
To book, call 647-748-1337 or email info@addictionclinictoronto.ca. Phones are answered seven days a week, 9 a.m. to 5 p.m., so you can reach someone on weekends too. If you are unsure which treatment is right for you, that is a normal question to bring to your first appointment — the doctor can talk it through with you. You can also read how booking works before you call.
What Happens at Your First Appointment
Your first visit starts with a conversation, not a lecture. The doctor will ask about your substance use history, your general health, any medications you take, and what you are hoping to change. This is a medical assessment, so it is confidential and treated the same as any other health concern — there is no judgement involved in these questions.
If OAT is a good fit, the doctor will explain how starting it works. Some options require you to be in mild withdrawal before the first dose; others do not — your doctor explains how to start safely. You will be walked through what to expect over the following days, and you can ask about timing, side effects, or anything else on your mind before deciding together on next steps.
Cost and OHIP Coverage
Physician visits for assessment and treatment are covered by OHIP, so there is no charge for seeing the doctor if you have a valid Ontario health card. If your OHIP coverage has lapsed or you do not have a card yet, mention this when you call so staff can explain what to expect.
The cost of medication is separate from the doctor visit and is usually covered in part or in full by the Ontario Drug Benefit program, private insurance, or other drug plans, depending on your situation. After your visit, your physician sends your prescription electronically to the pharmacy you choose, and pharmacy staff can tell you what your specific coverage looks like. Our guide to what OHIP covers has more detail.
What to Bring to Your Visit
Bring your OHIP card if you have one, a piece of photo ID, and a list of any medications or supplements you currently take, including anything not prescribed by a doctor. If you have had treatment for opioid or alcohol use before, notes on what was tried and how it went can help the doctor plan with you rather than starting from scratch.
You do not need to have everything figured out before you come in. It is enough to show up honest about where you are right now. Writing down a few questions ahead of time, such as how treatment might affect your daily routine or work, can help you get the most out of a short appointment.
Ongoing Care and Follow-up
Starting treatment is usually just the beginning. Follow-up appointments let the doctor check how you are responding, adjust your dose if needed, and talk through anything that has come up since your last visit, whether that is a side effect, a craving, or a change in your circumstances. These visits are also booked in advance by calling the clinic.
If you are in crisis or in immediate danger, this clinic is not an emergency service — please call 911 or ConnexOntario at 1-866-531-2600, which is available 24/7 for addiction support and can connect you to help right away. For everything else, our doctors are here to support you at a pace that works for you, one appointment at a time.
