Overview
What is an ADHD Assessment
An assessment is a structured clinical process that evaluates symptoms, functional impact, developmental history, and alternative explanations. It is not an online quiz and it is not a brief screening appointment.
People across Ontario often arrive with long-standing concerns: persistent inattention, disorganization, procrastination, emotional dysregulation, or inconsistent performance at school or work. An ADHD assessment clarifies whether ADHD is the best explanation—and what should happen next.
For many clients, the practical goal is documentation: a written report supporting accommodations or planning (school, workplace, exams, or other settings). For others, it is clinical clarity and a plan to address the specific difficulties that are present. Private assessment can be arranged without a physician referral — see ADHD testing in Ontario without a referral.

Fees & timing
Cost and timeline for ADHD assessment in Ontario
Private ADHD assessments are fee-for-service and not covered by OHIP. Exact fees and scheduling are confirmed at intake.
Families and adults commonly ask what an ADHD assessment costs and how long it takes before booking. A comprehensive private assessment typically includes clinical history, standardized measures, scoring and interpretation, a written report, and a feedback session. Fees vary by scope and complexity and should be confirmed directly — we outline what is usually included on our dedicated cost page.

FAQ
Common questions
These are high-frequency questions from adults, parents, and referring professionals.
How is an assessment different from an online test?
Online tests are typically screening tools. A clinical assessment integrates structured history, symptom patterns, functional impact, and clinically appropriate measures, then produces a documented interpretation and recommendations.
Do you assess both adults and children?
Yes. The approach differs by age and context. Children's assessments often include school functioning and developmental factors; adults' assessments focus on life history, executive functioning, and day-to-day impact.
Is this available across Ontario?
We serve clients across Ontario. Depending on your situation, some components may be completed virtually and/or in person at GTA clinic locations.
Do I need a physician referral for ADHD testing in Ontario?
No physician referral is required for a private ADHD assessment through our clinic. You can request a consultation directly. See our guide on ADHD testing in Ontario without a referral.
How much does a private ADHD assessment cost in Ontario?
Fees vary by clinic and scope. Our comprehensive ADHD assessment fee is confirmed at intake and typically includes history, standardized measures, a written report, and feedback. See our ADHD assessment cost in Ontario guide for what fees usually cover.
How long does an ADHD assessment take?
Timelines vary by age and complexity. Many private ADHD assessments are completed within approximately 3 weeks from intake to written report, including history, testing or rating measures, scoring, and feedback. Exact timing is confirmed at consultation.
What if it is not ADHD?
That outcome is still valuable. The goal is a defensible clinical answer and a practical plan. If another explanation better fits, recommendations focus on addressing the identified issues.
What is the next step if I want to proceed?
The simplest next step is to submit a consultation request. We will confirm fit, explain logistics, and outline the process before you commit.
