Private Wait
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.
You must see your pediatrician or family doctor to initiate a referral to the Hub.
Assessments are conducted by a team including developmental pediatricians and psychologists.
While the service is free, the wait time is the biggest barrier. Many London families wait 1.5 years before their first intake appointment.
Most private psychologists in London can see your child within 4-8 weeks, compared to 18 months via TVCC.
A private diagnosis from a Registered Psychologist is 100% valid for registering with the Ontario Autism Program.
Assessments cost $2,500 – $3,500. Many workplace benefits cover $1,000–$2,000 under "Psychology services."
