What are the best questions to ask an ABA provider?
Direct answer
When interviewing an ABA provider, ask about their **supervision model** and check that the supervisor is registered with the College of Psychologists and Behaviour Analysts of Ontario (look for R.B.A. (Ont.)). [ONTABA] Also ask about **staff turnover rates**, **data-sharing frequency**, and **how they handle challenging behaviors**.
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.

Context & Explanation
- A high-quality provider should be transparent about who is supervising your child's programs and how often they will meet with you for parent coaching. Including parents in autism therapy is critically important, according to the American Academy of Pediatrics. If a provider discourages you from observing sessions or doesn't offer regular data reviews, it is a significant red flag. You want a partner who views you as a co-therapist and gives you strategies to use at home.
Illustrative example
- This is a composite example, not a real family.
- The Nguyen family narrowed their search to two clinics. One clinic said, "We handle everything, just drop your child off." The other said, "We expect you to attend a 1-hour coaching session every two weeks and we will email you a progress graph every Friday." They chose the second clinic, because they wanted to learn the techniques themselves and use them at home.
