OHIP-COVERED ASSESSMENT

Public Assessment Hub: TVCC & Western Hub

Western Region ASD Diagnostic Hub

London families typically access public assessments through the Western Region ASD Diagnostic Hub. This hub is a partnership that includes TVCC (Thames Valley Children's Centre)and is connected to the provincial diagnostic network led by McMaster Children's Hospital.

Physician Referral Required

You must see your pediatrician or family doctor to initiate a referral to the Hub.

Multidisciplinary Team

Assessments are conducted by a team including developmental pediatricians and psychologists.

Waitlist Reality

While the service is free, the wait time is the biggest barrier. Many London families wait 1.5 years before their first intake appointment.

After diagnosis, families join the Ontario Autism Program (OAP) waitlist — a separate multi-year wait (5+ years (ETWO analysis of MCCSS FOI data)) for funded services, province-wide.

Estimated Wait

12–18 Months
