Direct answer
OAP does not require the diagnosing practitioner to be Canadian-licensed. International autism diagnoses are accepted by <a href="/oap-funding-guide" class="text-blue-600 hover:underline font-medium">AccessOAP</a> if they clearly state a DSM-5 ASD (or equivalent ICD-11 ASD) diagnosis, are in English or French (or accompanied by a certified translation), and identify the diagnosing practitioner with credentials. The key requirement is meeting DSM-5 ASD criteria — not where the assessment was performed.
Start with the short answer, then reveal deeper context where helpful.
Diagnoses from the US, UK, and Australia are generally accepted because their psychiatric and psychological standards closely align with DSM-5. US practitioners typically use DSM-5 directly. UK and Australian practitioners may use ICD-11, which includes equivalent ASD diagnostic criteria.
A certified translation is required if your diagnosis document is not in English or French. This means a sworn or certified translator — not Google Translate or an informal translation.
Most practical first step: contact the original diagnosing clinician and request a clarification letter explicitly adding DSM-5 ASD diagnostic language confirming the original findings meet DSM-5 criteria. Typically $200-$500.
If your child was diagnosed using DSM-IV categories (Autistic Disorder, Asperger's Disorder, PDD-NOS), the diagnosis will likely need to be updated to DSM-5 ASD before <a href="/oap-funding-guide" class="text-blue-600 hover:underline font-medium">AccessOAP</a> accepts it.

A certified translation is required if your diagnosis document is not in English or French. This means a sworn or certified translator — not Google Translate or an informal translation.
In Canada, certified translators are typically members of the Association of Translators and Interpreters of Ontario (ATIO) or equivalent provincial bodies. Translation agencies in Ontario that handle official documents can provide certified translations.
Most practical first step: contact the original diagnosing clinician and request a clarification letter explicitly adding DSM-5 ASD diagnostic language confirming the original findings meet DSM-5 criteria. Typically $200-$500.
If the original clinician is not accessible, a Canadian psychologist or developmental paediatrician can review the existing assessment and provide a DSM-5 confirmation letter — less expensive than a full re-assessment.
Full new Canadian DSM-5 assessment: private $2,000-$4,500 (4-8 weeks); public 12-24 months (OHIP-covered).

Options: request an updated DSM-5 letter from the original diagnosing practitioner (often a review appointment, $200-$500), or get a new Canadian DSM-5 assessment.
