Who We Are

OAC is a private facility that offers a wide range of psychological assessment and diagnostic services for children, youth and adults.

We provide diagnostic assessments and consultation services for children, youth and adults experiencing a wide range of challenges that may include: learning and intellectual difficulties, Autism Spectrum Disorders, Attention Deficit Hyperactivity Disorder, developmental disability and social emotional or behavioural difficulties as well as giftedness. Our assessments support tailored intervention by pinpointing areas of challenge and providing recommendations to improve functioning across areas. Diagnostic assessment can also facilitate access to services in a variety of educational and community settings.

We work with other professionals in the community, including family physicians, pediatricians, psychiatrists, child development centers, government ministries, and school personnel, to provide comprehensive assessment services and coordinated intervention.
