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.

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.
Why Timing Matters
A wait spans childhood.
Early support can help autistic children develop skills. Age six is not a clinical cutoff, and support can be beneficial at any age. Illustrative arithmetic only: registration at age three plus a five-year wait reaches age eight. Age six is a reference marker, not a clinical cutoff. This is not a prediction of funding, service access or developmental outcomes.
Example: an illustrative child's journey through the Ontario Autism Program
An assumed five-year wait from registration at age 3 reaches age 8. This is an example, not a typical or predicted service date.
| Measure | Age range |
|---|---|
| Illustrative age reference | Birth to age 6 |
| Example wait using the OAC-reported minimum (registered age 3) | Age 3 to age 8 (5 years) |
| Age at the end of this illustrative wait | Past age 6 |
Toddler treatment study
Dawson et al. (2010) randomly assigned 48 autistic toddlers aged 18–30 months to the Early Start Denver Model (ESDM) or community intervention for two years. The ESDM group had greater improvements in cognitive and adaptive outcomes. This study compared treatments for toddlers; it did not compare intervention before versus after age six or establish a universal multiplier for gains.
Support across ages
NIH notes that treatment can help at any age. Support should reflect the person’s needs; a wait does not determine an individual child’s future outcomes.
Ontario does not publish an age-at-registration breakdown for registrations without an active Core Funding Agreement. This example does not describe the age distribution of that group.
SourceDawson et al. (2010) · NIH: autism and support across ages. The illustrative wait uses the community report: 5+ years for families registered in August 2021 (community-reported, Ontario Autism Coalition, July 2026). This is not a provincial average.
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.
