Can I get retroactive OAP funding in Ontario?
No - OAP does not reimburse therapy costs paid before registration or during the waitlist. What support IS available immediately for families on the waitlist.
Direct answer
No. OAP does not provide retroactive funding for therapy expenses incurred before registration or during the waitlist period. OAP core clinical funding only pays for services bought within your funding period, not before your funding start date. Foundational Family Services ARE available immediately and free after AccessOAP registration.

Why retroactive funding does not exist
OAP core clinical funding only pays for services bought within your funding period, not before your funding start date. The guidelines do not describe a way to reimburse privately purchased therapy bought before that date.
There is no verified province-wide annual cost, so request provider-specific written quotes and confirm any reimbursement rule before purchasing care.
For families who age out before receiving an invitation, the entire private investment yields no OAP reimbursement.
Federal supports and tax relief
The Disability Tax Credit (DTC), Child Disability Benefit (CDB), and RDSP are federal supports independent of OAP status.
Therapy expenses paid privately while on the OAP waitlist may qualify for the Medical Expense Tax Credit (METC). Eligible expenses can include payments to behaviour analysts, speech-language pathologists, occupational therapists and psychologists. Confirm with a tax professional or CRA guidance.
METC does not replace the therapy cost - it provides partial tax relief.
School-based IEP supports
Ontario schools write Individual Education Plans (IEPs) under Ontario Regulation 181/98 for students identified as exceptional, and boards can also write IEPs for other students who need them. IEP-based supports are separate from OAP and do not require OAP registration.
For school-age children, an IEP can provide meaningful behaviour, communication, and learning support while families wait for OAP Core Clinical Services.

What IS available while waiting
- Foundational Family Services (free, immediate):
- Available at no cost immediately after AccessOAP registration. Includes family and peer mentoring, caregiver workshops and coaching, brief consultations, and transition supports. These are not Core Clinical Services (funded ABA/therapy) but they are free and you can use them at any point after registration.
- One-time interim funding (limited eligibility):
- check its current status on our OAP interim one-time funding status page before you plan around it, and contact the ministry's Central Resource Team at 1-888-444-4530 to ask whether your child may qualify. Only children registered by March 31, 2021 can qualify.
- Jordan's Principle (First Nations families only):
- A legal rule, applied by Indigenous Services Canada, so First Nations children do not face gaps or delays in getting government services. Separate from OAP.
Actions while you wait
- Register for Foundational Family Services the same week you join AccessOAP, since that support starts immediately and does not wait on a funding invitation.
- Ask the ministry's Central Resource Team (1-888-444-4530) whether your child could qualify for one-time interim funding; only children registered by March 31, 2021 can.
- If you are a First Nations family, ask about Jordan's Principle first, since it is separate from OAP and is meant to prevent gaps or delays in services.
- Keep every private therapy receipt in one folder with the provider name, service type, and date, because a tax professional needs that detail to check Medical Expense Tax Credit eligibility, and that credit only offsets part of the cost.
- For school-age children, ask the school directly about an Individual Education Plan while OAP funding is pending, since that support does not require OAP registration.
OAP does not reimburse past costs. Plan with that in mind.
