Autism Diagnosis in Ontario

An autism diagnosis provides clarity and guidance for parents seeking support for their child’s developmental, social, and communication needs. In Ontario, professional assessments are conducted by CRPO-certified therapists, ensuring legal compliance, professional standards, and evidence-informed practices.

As a CRPO-registered developmental therapist with Miller Method expertise, I provide child-centered assessments that are safe, compassionate, and individualized. Our process not only evaluates developmental and social communication skills but also integrates Miller Method strategies to make the experience supportive and meaningful for children.

Early diagnosis helps families access therapies, educational support, and developmental interventions that can improve social, emotional, and cognitive outcomes for children.

Autism assessments are comprehensive evaluations of a child’s:

Our assessments are conducted by CRPO-certified therapists trained in child psychotherapy and developmental therapies, ensuring accuracy, reliability, and adherence to professional standards.
