A naturopathic doctor (ND) in Ontario is a regulated health professional who combines conventional diagnostics, such as bloodwork and physical exams, with evidence-informed natural therapies like nutrition, botanical medicine, and lifestyle counselling. The goal is to understand the root cause of a health concern and support the body’s own healing, while working alongside your family doctor and any specialists.
This guide covers what NDs are trained to do, how they are regulated, what a first visit looks like, and what conditions a registered ND in Ontario commonly addresses.
Naturopathic doctors are regulated in Ontario
In Ontario, naturopathic doctors are regulated by the College of Naturopaths of Ontario (CONO) under the Naturopathy Act, 2007. Only registrants of CONO are legally permitted to use the protected titles “naturopathic doctor” or “ND.”
To register, an ND must:
- Complete a four-year, full-time, post-graduate program at a naturopathic medical school accredited by the Council on Naturopathic Medical Education (CNME).
- Pass the Ontario Biomedical Examination (a 150-question written exam covering body systems, physiology, and disease states; replaced NPLEX I in Ontario as of November 2020).
- Pass the Ontario Clinical Sciences Examination (a 200-question case-based exam testing clinical readiness; replaced NPLEX II in Ontario as of April 2019).
- Pass the Ontario Clinical (Practical) Examinations in naturopathic manipulation, acupuncture, and physical examination and instrumentation.
- Pass the online Ontario Jurisprudence Examination on the laws and standards governing practice in Ontario.
- Maintain continuing education and professional liability insurance each year.
This regulation means that an ND in Ontario is held to defined standards of practice, record-keeping, informed consent, and scope, the same way other regulated health professionals are.
Scope of practice: what an ND does
An ND’s day-to-day work looks more like primary care than people often expect. A registered ND in Ontario can:
- Take a thorough health history covering medical history, lifestyle, sleep, stress, nutrition, menstrual and reproductive health, and family history.
- Perform physical exams relevant to the concern (vitals, thyroid palpation, abdominal exam, etc.).
- Order and interpret lab work, including bloodwork, thyroid panels, hormone testing, iron studies, vitamin D, and select functional tests. See the lab test glossary for examples.
- Use clinical nutrition and dietary therapy based on the individual’s labs, symptoms, and goals.
- Prescribe botanical medicine and supplements where appropriate, with attention to interactions with prescription medications.
- Provide lifestyle counselling on sleep, stress, movement, and behaviour change.
- Use additional therapies such as acupuncture (with the appropriate CONO authorization).
- Refer to other providers (family doctor, mental health support, pelvic floor physiotherapy) when something is outside their scope.
NDs in Ontario do not perform surgery, do not prescribe most pharmaceutical drugs, and do not replace your family doctor. The intent is to work alongside your existing care.
What a first visit looks like
A first visit with Dr. Mariah, ND is typically 60 to 75 minutes. It is a detailed conversation about your health history, current concerns, and goals, and usually ends with an initial plan and any lab requisitions. For a full walk-through, see what to expect at your first naturopath visit.
A typical first visit covers:
- Your reason for booking and the timeline of the concern.
- Full health history, including past diagnoses, medications, supplements, surgeries, and family history.
- Lifestyle review: sleep, stress, energy, digestion, menstrual cycle, nutrition, movement.
- Review of any recent labs or imaging you bring with you.
- Initial assessment and a starting plan, which may include further testing, dietary changes, supplements, or referrals.
Follow-up visits are shorter, usually 30 to 45 minutes, and focus on lab results, plan adjustments, and tracking progress. Most patients can expect three to five follow-ups to see meaningful improvement with their primary concern, though this varies with complexity.
Conditions a registered ND commonly addresses
NDs in Ontario see a broad range of concerns, but each ND has their own areas of clinical focus. Dr. Mariah, ND focuses on:
- Hormone health, including PMOS (formerly PCOS), irregular cycles, painful periods, PMS, and perimenopause.
- Fertility support before, during, and between conception cycles.
- Thyroid concerns, including Hashimoto’s and subclinical hypothyroidism.
- Digestive and gut health, including bloating, IBS-type symptoms, and food sensitivities.
- Fatigue and low energy, including iron deficiency, sleep issues, and HPA-axis patterns.

How an ND works with your family doctor
A registered ND is not a replacement for primary care. The most useful framing is that your MD and ND answer different questions:
- Your family doctor (MD) rules out red-flag conditions, manages prescriptions, refers to specialists, and coordinates care covered by OHIP.
- Your ND focuses on root cause, daily inputs (nutrition, sleep, stress), targeted lab work, and supportive therapies that are typically out of scope or out of time for a 10-minute MD visit.
When something falls outside an ND’s scope, a good ND refers. When labs reveal something requiring conventional management, a good ND loops in your MD. For a fuller breakdown of how the two roles divide, see naturopath vs. family doctor.
Cost and coverage
Naturopathic care is not covered by OHIP. Most extended health benefit plans cover ND visits in part or in full, with annual limits that vary by plan. For full pricing detail and a breakdown of what insurance does and does not cover, see the cost of a naturopath in Ontario and is a naturopath covered in Ontario.
When a naturopathic doctor is a good fit
A registered ND is often a good fit when:
- You have ongoing symptoms but standard labs come back “normal.”
- You want help with the daily inputs (nutrition, sleep, supplements) that affect a chronic concern.
- You want longer appointment times and a more detailed lab workup.
- You want a second perspective alongside your family doctor or specialist.
It is not a substitute for emergency care, acute illness, or conditions that require prescription medication or surgery.
If you are weighing whether an ND is the right next step, the simplest way to find out is a first visit. Book a consultation and bring any recent labs or a list of your current concerns.
