Who can diagnose ADHD in Manitoba?

Physicians, nurse practitioners and registered psychologists each hold the authority to diagnose ADHD in Manitoba

Manitoba regulates diagnosis through The Regulated Health Professions Act, which reserves certain acts to members of regulated professions who are authorized by regulation to perform them. For ADHD, three professions qualify.

• Physicians, including family doctors and psychiatrists, are licensed by the College of Physicians and Surgeons of Manitoba (CPSM). A family doctor can diagnose adult ADHD directly or refer to a psychiatrist.
• Nurse practitioners are registered by the College of Registered Nurses of Manitoba (CRNM). CRNM policy cites section 5(1) of The Regulated Health Professions Act and section 3.9 of the College of Registered Nurses of Manitoba General Regulation, under which an NP may prescribe Schedule 1 drugs subject to the federal Controlled Drugs and Substances Act. The federal New Classes of Practitioners Regulations define a nurse practitioner as a registered nurse able to autonomously diagnose, order tests and prescribe.
• Psychologists are registered by the Psychological Association of Manitoba (PAM) under The Psychologists Registration Act, C.C.S.M. c. P190, in force since February 1, 1988. Section 11 of the Act restricts the title psychologist to registrants, and PAM's Verify a Member tool lets you confirm registration. Psychologists assess and diagnose but do not prescribe.

Whichever professional you see, ADHD is a clinical diagnosis: a structured interview against DSM-5-TR criteria, evidence of childhood onset, rating scales, and a check for other explanations. No blood test or brain scan confirms it, and a competent assessment can end with the conclusion that you do not have ADHD.

Manitoba's public ADHD service is for children and teens, not adults

Shared Health's Attention Deficit Hyperactivity Disorder Service, run through the Manitoba Adolescent Treatment Centre, serves children and youth aged 6 to 17 and their families, primarily in the Winnipeg region. A physician referral is required for psychiatric or medication consultation, and general enquiries go through Centralized Intake Child and Adolescent Mental Health at 204-958-9660. Shared Health does not list an equivalent adult ADHD program.

For an adult, the public route is therefore a family physician who either assesses you or refers you to a psychiatrist. Physician visits are insured by Manitoba Health, but psychiatry is by referral only, and the wait depends on the region and the practice. Psychologists in private practice charge fees, sometimes partly reimbursed by extended health plans. Nurse practitioners in the public system, for example in community health centres, can assess ADHD as part of primary care where their practice includes it.

Only physicians and nurse practitioners can prescribe, and stimulant prescriptions go through the M3P

Manitoba's prescription monitoring program is the Manitoba Prescribing Practices Program (M3P), and the College of Physicians and Surgeons of Manitoba's current M3P framework has been in effect since June 1, 2024. The College of Pharmacists of Manitoba's summary chart lists Controlled Drugs Part I, the federal category that covers the stimulant medications used for ADHD, among drugs that must be written on an M3P form signed by an authorized physician, nurse practitioner, dentist or veterinarian licensed in Manitoba.

Nurse practitioners need CRNM authorization before they can write these prescriptions: CRNM Policy AA-22, approved June 14, 2022 and revised July 7, 2026, requires the M3P presentation and post-test and, where entry education lacked controlled substances competencies, an approved course. An NP who has not met the requirements carries a condition on their certificate of practice, visible to pharmacists through the CRNM Nurse Check register. Stimulant medications help many adults and also carry risks, including sleep and appetite changes, raised heart rate and blood pressure, and misuse potential, which is why the monitoring applies to every prescriber.

A diagnosis from one professional is used by the others, with some limits

A psychologist's report cannot start medication on its own; it goes to a physician or nurse practitioner, who reviews it and decides on treatment. A nurse practitioner's diagnosis can go to your family doctor to support continuing care, and to a school or employer for accommodations. A physician's or NP's diagnosis can go to a psychologist or therapist for non-medication support such as cognitive behavioural therapy or coaching.

The receiving professional usually wants to see the criteria used, the childhood evidence, the conditions ruled out, and the clinician's registration number. Finding Focus issues a standard diagnosis letter for $49 and a healthcare-provider report for $99 for exactly this purpose, and adults already diagnosed elsewhere may qualify for 50% off the initial consultation; conditions apply. Fees are listed on the pricing page, and the Manitoba service is described on the Manitoba ADHD assessment page.

A family doctor is not obliged to take over prescribing after a private diagnosis, so it helps to ask your doctor in advance whether they will, and to send them the report. If they decline, the licensed nurse practitioners and clinicians working with Finding Focus can provide ongoing care through the optional membership at $29.99 per month or $74.99 per check-in without membership.

What every route in Manitoba has in common: DSM-5-TR criteria and a childhood history

CADDRA's Canadian ADHD Practice Guidelines, 4.1 Edition, were developed by a multidisciplinary team of paediatricians, psychiatrists, psychologists, family physicians and educators, and they describe assessment and treatment rather than reserving diagnosis to one profession. A Manitoba clinician following them will take a structured history, use validated rating scales, collect collateral information where possible, and consider other explanations before concluding.

1. Complete the free screener on the get-started page to see whether a full assessment is worthwhile; it is a screener, not a diagnosis.
2. Gather childhood evidence: report cards, a parent's recollections, or an early school assessment.
3. Note current medications and any diagnoses of anxiety, depression or sleep disorders, because the assessor needs to separate these from ADHD.
4. Choose a route based on what you need afterwards: medication (physician or NP), a psychometric report for school (psychologist), or both.

Adults assessed by the licensed nurse practitioners working with Finding Focus receive an up to 75-minute video assessment based on DSM-5-TR criteria, with results and a treatment plan often available within hours, and the assessment can conclude that ADHD is not the explanation.
