Private Mental Health Assessments for Ontario Residents

What is a psychodiagnostic assessment?

Individuals may seek a Psychodiagnostic assessment (also referred to as mental health assessments) to identify or clarify any mental health diagnoses, inform treatment, and/or to support accommodations at school or work. At OWPC, we assess for mental health conditions such as:

  • Attention-Deficit Hyperactivity Disorder (ADHD; for individuals over 16 only)

  • Anxiety Disorders

    • Generalized Anxiety Disorder, Panic Disorder, Phobias, Social Anxiety Disorder, Health Anxiety/Illness Anxiety

  • Obsessive Compulsive Disorder (OCD)

  • Eating Disorders and Body Image Issues

  • Depression, Bipolar and other mood disorders

  • Posttraumatic Stress Disorder (PTSD)

What does a mental health assessment at OWPC entail?

Our online mental health assessments are conducted by registered psychologists. The assessments usually involve a combination of clinical interviews, standardized questionnaires, and review of any relevant documents (e.g., report cards in the case of children/teens) or collateral information.

During the clinical interview you will be asked questions about your current mental health symptoms as well as information about the onset, frequency, and duration of these symptoms. The questionnaires you complete will be hand-picked for you based on your specific areas of need.

Once all of the information gathered is reviewed, your psychologist will meet with you to explain any potential diagnoses and provide recommendations. A written report is also provided and we can work with you to fill out any required forms.

How much does a mental health assessment cost?

Psychodiagnostic assessments vary in price depending on the amount of time it takes to complete it and are billed at the psychologist’s hourly rate. A general breakdown is as follows:

  • Clinical interview (1.5-2.5 hours)

  • Obtaining collateral information (if needed; e.g., interviewing teachers or reviewing report cards - 0.5 -1 hour)

  • Scoring and interpretation of psychometric questionnaires (1 hour)

  • Integrating all of the data obtained and preparing a written summary of the results of the assessment and/or completing any required forms (3-5 hours)

  • Feedback Appointment/Results session (0.5 -1 hour)

The total cost for an assessment with a full report is usually 6-10 hours.

    • full assessment with report = $1440-$2400

  • Psychologist - $225/hour

Frequently Asked Questions:

  • Psychoeducational assessments, also referred to as comprehensive psychological assessments, include an assessment of cognitive and academic functioning in addition to mental health symptoms. These types of assessments are usually recommended when there is a concern about a potential neurodevelopmental disorder such as a Learning Disability or Intellectual Disability or someone is experiencing academic difficulties.

    Psychoeducatonal assessments require in-person testing and are not offered by our clinic at this time.

  • We always begin with a clinical interview, which can vary in length (usually 1.5-3 hours). In addition to this, you/your child will also need to spend some time completing questionnaires. We may also need to connect with others for additional information (e.g., teachers, family doctors). Generally, we try to ensure that you receive “feedback” (i.e., results and recommendations within 3-4 weeks of receiving all of the information).

  • We offer ADHD assessments to individuals who do NOT have any concerns about their cognitive or learning abilities. Because cognitive or learning concerns can impact one's ability to sustain attention, we recommend that individuals who also have these concerns instead connect with a local in-person psychologist for psychoeducational testing.

*Please note that we DO NOT offer the following assessments at this time as they are out of our scope or require in-person testing:
