Where can I find autism diagnostic assessments in Ottawa?

Direct answer

In Ottawa, diagnostic assessments are offered by the **Children's Hospital of Eastern Ontario (CHEO)**, the provincial autism diagnostic hub for Eastern Ontario, or through private clinics. [CHEO] Fees vary by clinic, so ask each private clinic for a written quote and its current wait time.

What this means for your family

Call CHEO first to ask for their current wait time estimate, since the wait depends on the service and you want to compare it honestly against a private option before you decide anything. Check your workplace or family benefits plan for psychology coverage before booking privately, since even partial reimbursement can make a private assessment worth the added cost. If you also book a private clinic appointment, ask CHEO whether to stay on its wait list, and tell CHEO if you no longer need the appointment. Once you receive a formal diagnosis from either route, upload it to the AccessOAP portal the same week, since your place in the funding queue depends on that registration date, not your child's assessment date. Ask any clinic you contact whether they specifically diagnose autism, since not every child psychology practice offers that particular assessment, and ask for a written quote and its current wait time before you book.

Context & Explanation

  • CHEO is the provincial autism diagnostic hub for Eastern Ontario, and a doctor or nurse practitioner must make the referral. Ask CHEO for its current wait estimate when that referral is made. A private assessment is another way to get the written diagnosis that AccessOAP needs before you can register.

Illustrative example

  • This is a composite example, not a real family.
  • A family in Kanata suspected their 3-year-old was autistic and was placed on the CHEO wait list. They used their workplace benefits to cover part of the cost of a private assessment at a clinic in Nepean. Once they had a written diagnosis, they uploaded it to the AccessOAP portal to register their child for core clinical services.
