Quick Answer: Which Is Right for Your Family?
Private assessment ($2,500–$4,000, 3–8 weeks) is faster and provides detailed reports, but requires upfront cost. OHIP assessment (free, 12–24 months) removes financial barriers but delays access to early intervention. Both qualify for OAP funding. Choose based on your family's financial situation and urgency of diagnosis.

Which Families Should Choose Which Path
Choose OHIP/Public Assessment if:
- Cost is a significant barrier to your family
- You can manage the 12–24 month wait time
- Your child's immediate needs can be supported through other means during the wait
- You have access to a public assessment center with reasonable wait times in your region
Choose Private Assessment if:
- You need diagnosis quickly to access early intervention
- You have financial resources or private insurance coverage
- Your child's developmental concerns require prompt attention
- You want a more detailed diagnostic report
Consider Both Options:
- Use private insurance first; the government may cover any difference
- Request a private assessment if wait times in your region exceed provincial benchmarks
Impact on OAP Eligibility
Children diagnosed through either public or private assessment qualify for Ontario Autism Program (OAP) funding, provided the private assessor is a qualified assessor. OAP provides $5,000–$20,000 annually depending on age. Adults do not qualify for OAP funding but gain access to workplace accommodations, post-secondary supports, and Disability Tax Credit (DTC) eligibility.
