ABA is the most extensively researched intervention for autism spectrum disorder. It uses principles of learning and behaviour to build communication, social, and adaptive skills. Intensive early ABA (often in the range of 20 to 40 hours weekly for ages 2–6, as individualized with a clinician) is a common first-line treatment recommended by most clinical guidelines.

Speech-language pathologists (SLPs) work on communication, language comprehension, expressive language, articulation, and social communication. For autistic children who are non-speaking or minimally verbal, SLPs also introduce Augmentative and Alternative Communication (AAC) systems. School boards provide SLP services through IEPs, and private SLPs are eligible under OAP Core Clinical Services funding.
OAP Coverage: Speech-language therapy is an eligible expense under OAP Core Clinical Services funding when delivered by a registered SLP. Average cost: commonly around $120–$250 an hour privately (confirm with providers).
Occupational therapists help autistic children develop the skills needed for daily life, dressing, feeding, handwriting, play, and school participation. OTs also address sensory processing differences, fine motor delays, and executive function challenges. OT is typically recommended alongside ABA or speech therapy as part of a multi-disciplinary approach.
OAP Coverage: OT services are eligible under the OAP Childhood Budget when delivered by a registered OT (OT Reg. ON). Commonly around $130–$220 an hour (rates vary) privately.
Many autistic individuals experience sensory processing differences, being over-sensitive or under-sensitive to sound, touch, light, taste, or movement. Sensory integration therapy (typically delivered by OTs) uses structured sensory activities to help the brain process sensory input more effectively. This can reduce meltdowns, improve focus, and increase comfort in daily environments.
Note: Sensory integration therapy is often delivered as part of OT sessions. Look for OTs with sensory processing specialty training when accessing this approach.
AAC includes any communication method that supplements or replaces speech, from picture exchange systems (PECS) to high-tech speech-generating devices (SGDs) and apps like Proloquo2Go. Research shows AAC does not reduce speech development and can significantly increase overall communication. SLPs lead AAC assessment and implementation.
OAP Coverage: AAC devices and related SLP services are eligible under OAP Core Clinical Services funding. Some devices cost $3,000–$10,000+ but can be funded through Assistive Devices Program (ADP) as well.
OAP Core Clinical Services funding provides $6,600–$65,000/year based on your child's age and support needs. While waiting, interim one-time funding ($5,500 ages 6–17, up to $22,000 under 6) is available. All therapies listed on this page, ABA, SLP, OT, sensory, and AAC, are eligible expenses when delivered by approved providers. Families can mix and match therapies that match their child's needs.
77.5% of registered OAP families are currently unfunded and waiting. Average wait for Core Clinical Services: 5+ years (ETWO analysis of MCCSS FOI data).
Read: The OAP Waitlist CrisisThe brain is most plastic during the first six years of life. Research consistently shows that children who receive intensive, evidence-based intervention before age 6 achieve significantly better outcomes in communication, adaptive behaviour, and school readiness. The OAP waitlist crisis means most Ontario children are missing much of this early window.
The cost of waiting is irreversible.
Ontario's 5+ year waitlist (ETWO analysis of MCCSS FOI data) means children diagnosed at age 2 may not receive funded ABA therapy until age 7–9, well outside the peak early intervention window. Advocate for your child and access any available therapy now.

How many children are on the Ontario autism waitlist in 2026?
VerifiedAs of May 13, 2026, 91,974 children are registered with the Ontario Autism Program. However, only 20,711 (22.5%) have an active Core Funding Agreement. This represents ~300% growth in registrations since 2019, with 71,263 children still waiting for essential funding.

Is the Ontario Autism Program underfunded?
VerifiedYes. 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.

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
