Direct answer
To switch your OAP Core Clinical provider, give your current provider at least 30 days written notice of termination. Then select a new provider from the official OAP Provider List at oapproviderlist.ca. Contact your regional MCCSS office to facilitate the transition and ensure your childhood budget is transferred to the new provider without interruption.
Start with the short answer, then reveal deeper context where helpful.
If you are unsatisfied with your current OAP Core Clinical provider — whether due to clinical approach, communication, staffing changes, or geographic reasons — you have the right to switch providers at any time. The process involves: (1) Notify your current provider in writing that you are terminating the service agreement. The OAP requires approximately 30 days notice to allow for clinical closure and transition documentation. (2) Identify a new provider from the OAP Provider List (oapproviderlist.ca). Filter by region and service type to find providers accepting new clients.
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.

(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.

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.
