To register with the Ontario Autism Program, you need: a formal autism diagnosis report meeting DSM-5 criteria from a qualified professional, your child's Ontario health card (green card), proof of Ontario residency, and OAP consent forms. Some regions may request additional documentation from the diagnosing clinician. Submit through the <a href="/oap-funding-guide" class="text-blue-600 hover:underline font-medium">AccessOAP</a> portal at ontario.ca/oap or by calling 1-833-425-2445.
Start with the short answer, then reveal deeper context where helpful.
The Ontario Autism Program requires the following to register: (1) A formal autism diagnosis report from a qualified professional (registered psychologist, developmental pediatrician, child psychiatrist, or pediatrician with appropriate training). The report must document DSM-5 criteria met, assessment methods used, and clinical recommendations. A brief letter or note is not sufficient. (2) The child's Ontario health card (green-and-white photo card or red-and-white card for children under 16). (3) Proof of Ontario residency — acceptable documents include a utility bill, lease agreement, or government correspondence showing the Ontario address.
Some OAP regions may request additional documentation, such as a supplementary letter from the diagnosing clinician confirming the diagnosis remains current, or clarification if the assessment was conducted several years ago. If your child's assessment is more than 5 years old, prepare to explain whether the diagnosis has been reviewed more recently.

You will also need to complete OAP consent forms, which authorize MCCSS to access relevant information and share your file with service providers. These forms are available through the <a href="/oap-funding-guide" class="text-blue-600 hover:underline font-medium">AccessOAP</a> portal or by calling the OAP intake line at 1-833-425-2445.

For children in kinship care or whose legal guardian is not a parent, additional documents such as guardianship orders may be required — see the separate guidance on grandparent and guardian registration.

Ontario Autism Program — Registration Requirements and Document Checklist (2024)
Grandparents can access OAP funding if they are the child's legal guardian. Legal guardianship — not just physical custody — is required for OAP registration.
Registration means your child is enrolled with OAP. Waitlist means you are registered but waiting for a Core Clinical invitation. 67,509 children are registered but not yet receiving Core services.
In Ontario, autism can be diagnosed by psychologists, developmental pediatricians, psychiatrists, and some pediatricians. Learn the pathways and costs.
