Ontario provides publicly funded ADHD assessment, but access is complicated. Wait times at hospital-based programs routinely exceed 12 months. Understanding both pathways helps manage expectations and saves time.
The Public Pathway Through OHIP

A 28-year-old software developer in Toronto approached their family physician in January 2025. The GP referred them to the Centre for Addiction and Mental Health for assessment. CAMH confirmed the referral but quoted a 14 to 18-month wait for adult intake. OHIP covers psychiatrist-led evaluations entirely at zero out-of-pocket cost. The trade-off is significant delay that impacts work performance and daily functioning.
What OHIP Covers

OHIP fully covers assessments performed by physicians, including psychiatrists. Psychologist-led evaluations for adults are not covered under the provincial plan. This restriction channels patients toward psychiatrist referrals, extending wait times further. Post-diagnosis medication follow-ups with a psychiatrist remain fully covered. ADHD medications require separate coverage through Ontario Drug Benefit or private insurance.
Choosing the Private Route

After three months on the CAMH waitlist, the resident explored private options. Registered psychologists in Toronto charge between $2,200 and $3,500 CAD for ADHD evaluation. A midtown clinic offered a structured package at $2,800 CAD payable in two installments. The entire assessment was completed within three weeks from initial booking. Many employer benefit plans reimburse $1,000 to $2,000 CAD annually for psychological services.
Inside the Private Assessment

The first session was a 90-minute clinical interview covering developmental history and current symptoms. Standardized tools included the CAARS, WAIS-IV subtests, and the Test of Variables of Attention. A collateral interview with a partner confirmed symptom consistency across settings. The final report included a DSM-5 diagnosis and detailed treatment recommendations. The family physician accepted this report directly for medication prescribing.

Practical Advice for Ontario Residents
Both public and private ADHD assessment routes are valid in Ontario. If cost is the priority, request a GP referral to a hospital program as early as possible. For faster access, budget $2,200 to $3,500 CAD and check your employer benefits for reimbursement.
