How to Switch Your OAP Core Clinical Provider
Direct answer
To switch your OAP Core Clinical provider, give your current provider written notice that you are ending the agreement. Most agreements ask for about 30 days, but check your own. Then pick a new provider from the official OAP Provider List at oapproviderlist.ca. Contact your regional MCCSS office to help with the move and to transfer your childhood budget to the new provider without a break in service.

Why Timing Matters
The wait outlasts the window.
Clinical research (American Academy of Pediatrics; Hyman et al., Pediatrics 2020) identifies birth to age six as the peak neuroplasticity window for autism intervention. Ontario's reported minimum wait is 5+ years for families registered in August 2021 (community-reported, Ontario Autism Coalition, July 2026).
Example: an illustrative child's journey through the Ontario Autism Program
Registered at age 3. Services begin at age 8, after 5+ years for families registered in August 2021 (community-reported, Ontario Autism Coalition, July 2026), most of it inside the intervention window.
| Measure | Age range |
|---|---|
| Early-intervention window (AAP) | Birth to age 6 |
| Example wait using the OAC-reported minimum (registered age 3) | Age 3 to age 8 (5 years) |
| Age when services begin in this example | Past age 6 |
✓ Intervention before 6
Research shows 2× greater gains in cognitive and adaptive functioning. Some children lose their diagnosis entirely. The brain's plasticity makes early therapy dramatically more effective.
◌ Intervention after 6
Reduced neuroplasticity means slower progress, higher lifetime costs, and poorer outcomes. Every year of delay narrows the range of achievable milestones. Ontario's waitlist guarantees this for most families.
Of the 71,263 children on the unfunded backlog, the majority were registered between ages 2 and 4. At the current pace, most will age past 6 before receiving any core funding , missing the window that the American Academy of Pediatrics and every major autism research body identifies as critical.

Steps to Switch OAP Providers
- You can switch OAP Core Clinical providers at any time, for any reason — the clinical approach, poor communication, staffing changes, or a move. The process has two steps. (1) Tell your current provider in writing that you are ending the service agreement. Most agreements ask for about 30 days so the clinician can close out and hand over notes; check the terms in your own agreement. (2) Pick a new provider from the OAP Provider List at oapproviderlist.ca, filtering by region and service type to find providers taking new clients.
- (3) Contact your regional MCCSS office at 1-833-425-2445 to inform them of the switch and request assistance with transferring your childhood budget and file to the new provider. (4) Work with both providers during the transition to transfer your child's behaviour plan, assessment data, and progress notes to minimize disruption to programming.
What Happens to Your OAP Budget When You Switch
- Your OAP childhood budget follows your child - it is not locked to a specific provider. When you switch providers, the remaining budget for the fiscal year transfers to your new provider. Any amounts already invoiced by the previous provider for services rendered are not recoverable, but unused budget carries forward to the new provider within the same fiscal year.
- If the provider transition spans a fiscal year boundary (April 1), be aware that unused funds from the prior year are forfeited regardless of the transition. Plan your switch timing to minimize budget waste, and confirm the budget transfer process directly with your MCCSS regional office.
Frequently asked questions
Yes. You are not locked into any OAP provider. Give your current provider written notice — most agreements ask for about 30 days, so check yours — and pick a new provider from the OAP Provider List at oapproviderlist.ca. Your MCCSS regional office handles the budget transfer.
Provider transitions can cause short-term disruption to therapy programs. Request that your current provider share all clinical documentation, behaviour plans, and progress notes with the new provider. A brief overlap period for joint meetings may reduce transition gaps.
Search the OAP Provider List at oapproviderlist.ca, filtering by region and service type. Call providers directly to ask whether they are taking new clients. Waits for new clients can run several months even with an approved provider.
