Government of Ontario · Verified 2026-08-10
In brief
| Criterion | Requirement | Source |
|---|---|---|
| Age | Children can qualify for OAP from birth until their 18th birthday | Government of Ontario |
| Residency | The published Ontario Autism Program registration criteria require that the child currently live in Ontario | Government of Ontario |
| Diagnosis | OAP requires a written diagnosis of Autism Spectrum Disorder (ASD) based on DSM-5 criteria from a qualified professional. | Government of Ontario |
Children can qualify for OAP from birth until their 18th birthday. The age cutoff is strict, once a child turns 18, they are no longer eligible for OAP Core Clinical Services funding or interim one-time funding.
Important: There is no equivalent autism-specific funding for adults in Ontario. Adults must access supports through Ontario Disability Support Program (ODSP), Passport Funding, or adult developmental services.
The published Ontario Autism Program registration criteria require that the child currently live in Ontario. Canadian citizenship is not listed as a separate criterion. AccessOAP can confirm which identity and residency documents apply to your family.
Documentation: AccessOAP confirms the identity and residency documents needed for a specific application.
OAP requires a written diagnosis of Autism Spectrum Disorder (ASD) based on DSM-5 criteria from a qualified professional.
Older diagnoses still qualify: If your child has a previous diagnosis of PDD-NOS, Asperger's Syndrome, or Autistic Disorder (DSM-IV), these now all fall under Autism Spectrum Disorder and qualify for OAP.
How long does autism diagnosis take in Ontario?
Ontario does not publish one province-wide wait for a public autism diagnosis. Waits are not published centre by centre either, so ask the assessment centre for its current wait when you are referred. The diagnosis wait comes before OAP registration, so it is not counted in OAP waitlist figures. Pending verification: Editorial review not recorded. Excluded from citation-ready exports.

Can autistic students get an educational assistant (EA)?
School boards may assign educational assistants (EAs) to autistic students based on needs identified through the IEP process. How EAs are allocated varies by board and school, so ask the principal how support is assigned for your child. Pending verification: Editorial review not recorded. Excluded from citation-ready exports.
