OAP, IBI, and ABA are not competing therapies you choose between. The Ontario Autism Program (OAP) is the government funding mechanism. Applied Behaviour Analysis (ABA) is the scientific approach and primary therapy the funding pays for. Intensive Behavioural Intervention (IBI) is a specific, highly intensive application of ABA — typically 20–40 hours per week — used for young children during their peak neuroplasticity window.
Start with the short answer, then reveal deeper context where helpful.
The Ontario Autism Program (OAP) is the provincial government framework that provides funding to families of children with autism. It is not a therapy itself, but a funding system delivering "Childhood Budgets" or "Core Clinical Services" allocations. OAP is administered by the Ministry of Children, Community and Social Services (MCCSS), with intake handled by <a href="/oap-funding-guide" class="text-blue-600 hover:underline font-medium">AccessOAP</a>.
Applied Behaviour Analysis (ABA) is the underlying science of learning and behaviour. ABA therapy teaches functional skills (communication, daily living, social) and addresses interfering behaviours. It can be delivered in focused (a few hours per week targeting specific goals) or comprehensive (intensive, multi-domain) formats.
Intensive Behavioural Intervention (IBI) is a comprehensive, highly intensive application of ABA therapy. It typically involves 20 to 40 hours per week of one-on-one therapy focused on broad developmental goals for young children during their peak neuroplasticity window (ages 0–6).
Parents do not choose between OAP and ABA/IBI. You register for the OAP to secure government funding, and once funded, you use those dollars to purchase ABA or IBI services for your child. Because the OAP waitlist is currently 5+ years long, families who want early intervention during the critical 0–6 neuroplasticity window must typically pay privately out-of-pocket while waiting for their <a href="/oap-funding-guide" class="text-blue-600 hover:underline font-medium">OAP funding</a> invitation to arrive.

As of January 2026, 88,175 children are registered in the OAP, but 67,509 (76.6%) are waiting without active core funding. The average wait is 5+ years. When families finally receive an invitation, the funding amount ($6,600–$65,000/year) is determined by a needs assessment — not family income.

It can be delivered in focused (a few hours per week targeting specific goals) or comprehensive (intensive, multi-domain) formats.
ABA is provided by Board Certified Behavior Analysts (BCBAs), Registered Behavior Technicians (RBTs), and OAP-approved clinical supervisors. Hourly rates in Ontario typically range from $60 to $150. Total annual costs vary widely — $10,000 to $80,000+ — based on the number of hours prescribed and supervision model.
Intensive Behavioural Intervention (IBI) is a comprehensive, highly intensive application of ABA therapy. It typically involves 20 to 40 hours per week of one-on-one therapy focused on broad developmental goals for young children during their peak neuroplasticity window (ages 0–6).
IBI is delivered by Clinical Supervisors (BCBAs) and behaviour therapists in specialized clinics, homes, or day programs. Annual costs can easily reach $60,000 to $95,000+ due to the sheer volume of hours required. IBI can be funded through OAP allocations once invited, or paid privately out-of-pocket while waiting.

The structural problem: early intervention matters most for children under 6, but the average 5-year wait means most children miss their peak window entirely unless their family can afford $60,000+ annually in private therapy costs.

Verified Facts
Early Start Denver Model (ESDM) delivered to children aged 18–30 months produced significant gains in IQ, adaptive behaviour, and autism severity — some children no longer met diagnostic criteria at follow-up
Cochrane systematic review finds evidence that early intensive behavioural intervention (EIBI) may produce positive effects on adaptive behaviour and communication for young children with ASD (low certainty of evidence)
WHO recommends accessible, community-based early interventions for children with autism — timely evidence-based psychosocial interventions improve communication and social engagement
88,175, children are registered in the Ontario Autism Program
According to the FAO (2020 report), OAP funding covers less than one-third of estimated need at 2018-19 service levels
