How to choose an addiction counselor
- Check the license with the state or provincial board that issued it; most boards publish a free online lookup.
- Make sure addiction counseling is a regular part of their work, and ask what approach they use and why.
- Ask which credential the counselor holds (for example a state addiction counselor certification, LPC or LCSW).
- Ask whether they work with a physician if medication for addiction treatment is part of your plan.
- Ask about fees, insurance and the cancellation policy before the first session. In the US, if you are uninsured or paying yourself, you can ask for a good faith estimate of expected charges.
- Check practical fit: in-person or online sessions, evening times, and how soon they have an opening.
- After a few sessions, ask yourself whether you feel heard. Changing to a different provider is common and fine.
Questions to ask an addiction counselor
- Are you accepting new clients, and how soon could I start?
- Which license do you hold, and in which state or province?
- How much of your work is addiction counseling?
- Do you offer individual sessions, groups or an intensive outpatient program?
- What do you charge per session, and do you take my insurance or provide a superbill?
- Do you offer online sessions?
- What is your cancellation policy?
- What do you keep confidential, and when would you have to share information?

What should I do if I need help right now?

The highest-ranked open Saturdays are York Addiction & Mental Health (#1), Canadian Centre for Addictions - Call Centre in Toronto, Ontario, CA (#2) and Addiction Canada (#3). Posted hours are office hours; many practices also offer evening or online sessions by appointment.
What Google rating do Markham addiction counselors have?
The median Google rating among 72 rated addiction counselors in Markham is 4.6★, with a median of 22 reviews. Progress Centre Medical has the most, 1,517 reviews, and ranks #20. We adjust ratings for review count, so a few five-star reviews cannot top the list.
How does RankedPsychologists rank addiction counselors?
Each addiction counselor gets a 0–100 RP Score from eight published factors, led by reputation (25%), specialty focus (25%), proximity (15%) and availability (10%). A practice with no Google reviews scores zero on rating, review volume and recency; other factors we cannot measure are left out. Only practices with a confirmed specialty and 3 or more reviews, or a claimed profile, are ranked.
Do addiction counselors outside Markham count in this ranking?
Yes, if they are within 80 km of the Markham city centre, our service radius for addiction counselors. Each listing shows where the practice is based and how far away it is. Proximity is 15% of the RP Score, so a nearby practice gets a small edge.
Can addiction counselors pay to rank higher on RankedPsychologists?
No. The RP Score never reads payment status, and this ranking has 0 paid placements. Up to 3 Featured practices may appear above the list, labelled Sponsored and showing their honest rank.
How are addiction counselors in Markham ranked?
Each practice gets an RP Score from 0 to 100 from 8 published factors, including its Google rating, how clearly it focuses on addiction counseling and how close it is. Sponsored placements are shown separately and never change rank. The score does not measure treatment outcomes.
What is the difference between outpatient addiction counseling and rehab?
Outpatient counseling means regular sessions while you live at home and keep working; intensive outpatient programs meet several times a week. Residential rehab and medical detox happen in a facility. Withdrawal from alcohol and some drugs can be medically dangerous, so speak to a doctor before stopping if you drink or use heavily every day.
Can I see an addiction counselor online?
Often, yes. Licensing generally follows where you are during the session, so the provider needs to be licensed or authorized there. In the US, psychologists in PSYPACT member states can offer telepsychology to clients in other member states; counselors and social workers have their own rules. In Canada, ask whether the provider is registered in your province.
What if I need help right now?
Do not wait for a consultation. Call or text 988 (US and Canada) if you are in crisis or thinking about suicide, at any time. In an emergency, call 911.
