Does Ontario OAP fund IBI separately from ABA?

Since the 2019 OAP reform, IBI is no longer a separate funded stream. Both IBI and ABA are funded under OAP core clinical services. Your child's individualized service plan determines the recommended hours and intensity — not a separate IBI vs ABA eligibility determination.

What is the difference between IBI and ABA?

IBI (Intensive Behavioural Intervention) is a high-intensity application of ABA principles, typically 20–40 hours per week, designed for young children (usually under 5). Standard or focused ABA involves fewer hours (5–20/week) and is suitable for a broader age range. IBI is a type of ABA — all IBI is ABA, but not all ABA is IBI.

How many hours of ABA does OAP fund?

OAP core clinical services fund hours based on your child's individualized service plan. Legacy interim funding was one-time and limited to registrations before April 1, 2021.

IBI vs ABA in Ontario: Differences, OAP Funding & What Your Child Needs

Intensive Behavioural Intervention (IBI) and Applied Behaviour Analysis (ABA) are often confused — and have historically been funded differently under Ontario's autism programs. This comparison clarifies the distinction and what it means for OAP funding.

Quick summary

Side-by-side comparison of IBI vs ABA autism services
IBI is an intensive use of ABA principles. Current OAP funding terms, private costs, and hour recommendations need source checks. The cited EIBI review describes possible benefits with low-certainty evidence.

Is the Ontario Autism Program underfunded?

Verified

Yes. The Financial Accountability Office (FAO) determined that $1.35 billion annually is needed to serve all registered children at 2018-19 service levels. The 2026-27 Ontario Budget allocated $965 million, leaving an estimated $385M+ annual shortfall. This gap is the primary driver of the perpetual 91,974+ child waitlist.

How much does Ontario fund for autism treatment?

Verified

Core Clinical Services funding ranges $6,600-$65,000 per year based on age/needs (with a total OAP budget of $965M for 2026-27, up from $779M in 2025-26, per the Ontario Budget tabled March 26, 2026). This is direct funding—families choose public or private providers. However, intensive ABA therapy can cost up to $95,000 USD/year (2020 US cost estimate cited in FAO 2020 report; Canadian costs vary), leaving significant out-of-pocket gaps.
