Frequently asked questions, Toddlers (0-3 Years)

Yes. OAP Caregiver-Mediated Early Years Programs are available for children aged 12-48 months without requiring a formal diagnosis. Contact AccessOAP to register your child.

Qualified professionals can diagnose autism in toddlers. Public assessment waits are not published province-wide, so ask the assessment centre for its current wait. Private assessments may be faster; ask for a written fee quote.

Register with AccessOAP immediately to timestamp your place in line. Then request a developmental assessment and ask about Caregiver-Mediated Programs that do not require a diagnosis.
