Compare every evidence-based autism therapy available in Ontario — ABA, speech, occupational therapy, sensory integration, and AAC. Understand OAP coverage and how to access each approach in 2026.
Last updated: March 2026
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 (20–40 hours/week for ages 2–6) is the standard 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 the OAP Childhood Budget.
OAP Coverage: Speech-language therapy is an eligible expense under the OAP Childhood Budget when delivered by a registered SLP. Average cost: $120–$250/hour privately.
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). Average cost: $130–$220/hour 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 the OAP Childhood Budget. Some devices cost $3,000–$10,000+ but can be funded through Assistive Devices Program (ADP) as well.
The OAP Childhood Budget provides $5,000–$55,000/year depending on your child's age and needs. 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.
76.9% of registered OAP families are currently unfunded and waiting. Average wait for Core Clinical Services: 5–7 years.
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 this critical window.
The cost of waiting is irreversible.
Ontario's 5–7 year waitlist 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.
