Access OAP will conduct a Determination of Needs assessment to identify your child's service requirements. Complete this as quickly as possible, delays at this stage cost time in the overall queue.
Your child is now in the invitation queue. Position is determined solely by registration date. During this period, pursue foundational family services, school IEP accommodations, and any interim funding opportunities that become available.
When your child's invitation arrives, you will select a registered OAP provider and begin accessing core clinical services funded through childhood budgets (amount varies by age and assessed needs). Review your options carefully, you can change providers if needed.

Before joining the OAP waitlist, Ontario diagnostic waitlists average 12–24 months at public hospitals. This pre-waitlist delay means total time from first concern to therapy often exceeds 5–7 years, an invisible bottleneck in official statistics.
