Opioid addiction treatment steps for starting OAT in Ontario

If you or a loved one needs help now, clear opioid addiction treatment steps reduce delays and lower risk. This article gives a concise four-step starter path to begin opioid agonist therapy (OAT) in Ontario, then names specific mistakes people make before committing to a clinic or medication and how to verify each item immediately.

Quick starter path: first four opioid addiction treatment steps to begin OAT today

Use this starter path when you want same-day access or a rapid appointment. Road To Recovery offers same-day intake where new OAT patients are triaged by a nurse and then seen by a physician the same day they start, which can shorten delays to treatment. Begin with these four steps.

Step 1: Contact a clinic or use the online intake portal

Open the clinic intake portal or call to request an urgent OAT intake. If a clinic advertises same-day begins, confirm you will be seen first by a nurse for triage and then by a physician that day. Use the clinic portal on the Road To Recovery website to start intake and upload basic information before you arrive, which speeds triage and reduces time in clinic.

Step 2: Nurse triage checklist

At triage a nurse will take a brief medical history, record current medications and assess withdrawal risk. Expect questions about recent opioid use, other substances, medical conditions, and pregnancy status when relevant. Triage helps the team pick a safe first medication and plan monitoring. Be honest about recent use so the team can avoid induction approaches that risk precipitated withdrawal.

Step 3: Physician assessment and medication plan

The physician will review your history, set a medication-assisted treatment plan, explain options and risks, and arrange follow-up. Opioid agonist therapy is a medical treatment for opioid use disorder that aims to reduce harms and allow engagement in therapy and other supports, so expect a focus on safety and continuity of care. For an official overview of OAT as a treatment approach see Health Canada guidance on opioid use disorder and treatment.

Step 4: What happens after you start

After a first dose you will be monitored for a period set by the clinic. The team will schedule follow-up visits, supervised dosing if required, and any urine screening or lab tests the clinician deems necessary. Medication choice, dose adjustments and take-home rules are decided over time with your care team. Bring any questions about work, driving and side effects to follow-up visits so adjustments can be made safely.

What to bring and what to expect at a same-day intake

Arrive prepared to speed your assessment and avoid repeat visits. Bring the following items and expect a few standard clinical checks.

• Personal identification and your provincial health card if available.
• A list of current prescriptions, over-the-counter drugs, and any prior OAT history.
• Contact information for an emergency contact or next of kin.
• Any relevant medical records or recent hospital discharge notes if you have them.
• A payment method if the clinic requires fees for services not covered by provincial care.

Do not bring

• Illicit substances into the clinic, which can complicate assessment and safety monitoring.
• Large quantities of cash or valuables that are unnecessary for medical visits.

Questions to ask at intake

• Will I be seen by a nurse and physician today for OAT initiation?
• Which medications do you offer and how will you decide what is right for me?
• How will my privacy be protected and who will see my records?
• What follow-up and counselling supports are available or referred?

Medication options and decision checks: Methadone, Suboxone, Sublocade and Kadian

Common medications used in OAT include methadone, buprenorphine-naloxone (Suboxone), monthly buprenorphine injection (Sublocade), and sustained-release oral morphine (Kadian). Before accepting any medication, run these decision checks with your clinician and pharmacist.

Methadone: what to check

• Ask about cardiac screening if you have heart disease or take medications that affect heart rhythm.
• Confirm supervised dosing rules and how take-home doses are earned or issued.
• Discuss work and driving safety since methadone can cause drowsiness when treatment starts or the dose changes.

Suboxone (buprenorphine-naloxone): what to check

• Confirm how induction is scheduled to avoid precipitated withdrawal, and whether microinduction is available if you cannot tolerate a traditional start.
• Ask about interactions with other medicines you take and about plans for dose adjustments.

Sublocade monthly injection: what to check

• Verify eligibility and whether you need a period of stability on sublingual buprenorphine before switching to monthly injection.
• Ask about injection-site reactions, clinic visit requirements, and what happens if you miss a scheduled dose.

Kadian sustained-release morphine: what to check

• Confirm why Kadian is being recommended, check for allergy or opioid tolerance issues, and ask about supervised versus take-home dosing.
• Discuss potential side effects and how follow-up care will monitor safety.

Health Canada describes OAT as medical treatment that reduces harms and supports engagement in therapy and other life areas, so shared decision making with your clinician is important. For more information see Health Canada guidance on opioid use disorder and treatment.

Clinic selection: common mistakes to avoid and how to verify them

Choosing a clinic is a high-stakes decision. Below are specific mistakes people make and exact verification steps to avoid them.

1. Assuming “fast start” without confirming team flow

   Do not accept a generic promise of rapid starts. Call and ask whether new OAT patients are triaged by a nurse and then seen by a physician the same day. If a clinic cannot confirm that flow, ask about the next available appointment and urgent alternatives.

2. Not checking confidentiality and information sharing

   Ask the clinic to explain their privacy policy and who can access your records. Confirm whether records will be shared with other health services, employers or child protection authorities without your consent unless legally required.

3. Missing psychiatry and mental health linkage

   Verify that the clinic can arrange psychiatry or mental health referrals locally or virtually. Road To Recovery coordinates referrals with partners and can explain typical referral waits and interim supports. Ask how long waits usually are and whether the clinic provides short-term counselling while you wait.

4. Overlooking supervised dosing and take-home rules

   Different clinics use different supervised dosing policies. Ask how supervised dosing works, how and when take-home privileges are awarded, and what to expect on missed-dose days.

5. Ignoring special needs for parents and children

   If you are a parent, ask whether the clinic offers support for child protection concerns and how they coordinate with child protection services if needed. Knowing this in advance helps you plan visits and required documentation.

6. Failing to confirm medication options on site

   Before you accept an intake, confirm the clinic actually provides the medication you prefer. Some clinics offer a wide range of options, others offer only select medications.

7. Not verifying practical supports

   Ask about walk-in services, pharmacy arrangements for dosing, transportation support, and whether the clinic offers a medical walk-in for related primary care needs.

Sample questions to ask before booking

• Do you offer same-day nurse triage and physician assessment for new OAT patients?
• Which OAT medications do you offer and how do you decide which is right for a patient?
• How do you coordinate psychiatry referrals and what virtual options do you use?
• What is your privacy policy and who has access to my records?

Urgent access alternatives: RAAM clinics and walk-in options

Rapid access addiction medicine clinics, or RAAM clinics, are low-barrier services that offer same-day or walk-in care for people with high-risk substance use or opioid use disorder. Use RAAM when you need immediate assessment and cannot wait for a scheduled intake. Health Canada describes RAAM as an accessible option that complements scheduled OAT services. If a scheduled intake is delayed, ask your local health services about RAAM or equivalent walk-in clinics in your area and keep those numbers handy as a backup.

Psychiatry, mental health and family supports during treatment

Integrated mental health care improves outcomes for many patients. Verify whether your clinic coordinates psychiatry referrals locally or virtually, and ask how wait lists are managed. Family members can play a supportive role while respecting patient confidentiality. For guidance on family involvement, resources and how to offer help safely, see the clinic family support page.

How virtual psychiatry referrals work

Virtual referrals typically require a clinician to submit information to a psychiatry partner who will arrange an appointment by phone or video. Ask whether the clinic will help with referral paperwork, whether virtual options are available to reduce travel and how urgent needs are triaged.

What family members should know and ask

• Ask how family members can be involved in care while respecting patient confidentiality.
• Request resources or referrals the clinic provides to families, including education on overdose prevention and naloxone use.

Practical decision criteria, common objections and next steps

Common objections include privacy worries, fear of stigma, concerns about medication side effects, and employment or driving implications. Use these decision criteria to resolve them before you start.

• If privacy is a concern, request the clinic privacy policy in writing and ask who can legally be given access to your records.
• If you fear stigma, ask about the clinic environment, whether staff are trained in addiction care, and what supports are available for nonjudgmental counselling.
• If you worry about side effects or work safety, ask the prescriber about expected effects, recommended time off if needed, and whether medical notes for an employer are provided.

Next steps: complete the online intake on the clinic website, call the clinic to confirm same-day triage and physician availability if you need urgent care, and keep a RAAM or walk-in clinic number handy as a backup.

Frequently asked questions

How do I start opioid addiction treatment steps in Ontario the same day?

Begin by using a clinic online intake or calling to request an urgent OAT appointment. Confirm that the clinic will triage you with a nurse and then offer physician assessment the same day, and bring ID and medication lists. If same-day intake is not available, ask about RAAM or walk-in alternatives. See Health Canada for an overview of OAT as a treatment option.

What should I bring to a methadone or Suboxone intake appointment?

Bring photo ID, a list of current and recent medications, a health card if available, an emergency contact, and any relevant medical records. Be prepared for a brief medical history, possible urine screening, and informed consent discussions.

How do I know which opioid agonist therapy medication is right for me?

Medication choice depends on your opioid use history, medical conditions, pregnancy status, previous responses to OAT, and practical needs like work or travel. Discuss these factors openly with the clinician so decisions are made safely and collaboratively.

What is a RAAM clinic and when should I use one instead of a scheduled OAT intake?

RAAM clinics provide rapid, low-barrier assessment and can start OAT or arrange urgent supports when you cannot wait for a scheduled intake. Use RAAM for same-day needs, high-risk use, or when local access is limited. Health Canada describes RAAM as a complementary model to scheduled care.

Will my opioid addiction treatment be confidential and who will have access to my records?

Clinics are bound by privacy laws and clinical confidentiality, but there are legally required exceptions. Ask the clinic for their privacy policy and for a clear explanation of who will see your records and under what circumstances information may be shared.
