Questions to discuss with a clinician

  1. Consult with a developmental pediatrician or psychologist after diagnosis.
  2. Consider your child's specific challenges (communication, sensory, motor skills), their age, and the available funding.
  3. Families can discuss the evidence and goals for an individual child with a qualified clinician.

COMMUNICATION

Speech-Language Therapy (SLP)

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 may be eligible under OAP Core Clinical Services when delivered by a registered SLP. Ask providers for current fees and confirm eligibility with AccessOAP.

Speech Therapy Ontario Guide
DAILY LIVING

Occupational Therapy (OT)

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 may be eligible under OAP Core Clinical Services when delivered by a registered OT. Ask providers for current fees and confirm eligibility with AccessOAP.

OT for Autism Ontario Guide
SENSORY PROCESSING

Sensory Integration Therapy

Many autistic individuals experience sensory processing differences, being over-sensitive or under-sensitive to sound, touch, light, taste, or movement. 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.

COMMUNICATION ACCESS

Augmentative & Alternative Communication (AAC)

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. Ask providers about device costs and confirm eligibility with AccessOAP and the Assistive Devices Program.

FUNDING

Using OAP Funding for Therapy

OAP Core Clinical Services funding provides $6,600–$65,000/year based on your child's age and support needs. Interim one-time funding remains available only to children registered by March 31, 2021. See the Ontario program details. All therapies listed on this page, ABA, SLP, OT, sensory, and AAC, are eligible expenses when delivered by approved providers.

Early Intervention Is Critical

Research on early autism interventions reports outcomes that vary by intervention, goal, and study. Families can discuss the evidence and goals for an individual child with a qualified clinician.

How many children are on the Ontario autism waitlist in 2026?

As 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?

The 2026-27 Ontario Budget allocated $965 million for autism services, up from $779 million in 2025-26, while 91,974 children are registered.

Frequently Asked Questions

OAP Core Clinical Services funding can be used for ABA therapy, speech-language therapy, occupational therapy, and other evidence-based interventions, including intensive ABA-based programs. All therapies must be delivered by OAP-approved providers.

Applied Behaviour Analysis (ABA) has the strongest research base for autism, particularly for young children under 6. However, effectiveness depends on the individual. Many families combine ABA, speech therapy, and occupational therapy. Early intervention with any evidence-based approach produces the best outcomes.

Consult with a developmental pediatrician or psychologist after diagnosis. Consider your child's specific challenges (communication, sensory, motor skills), their age, and available funding. ABA is typically first-line for young children; speech therapy is essential if communication is delayed; OT helps with daily living and sensory needs.

Yes. Many families access therapy privately while on the OAP waitlist. The Disability Tax Credit can offset some costs. School boards provide speech and OT through IEPs. Some community agencies offer subsidized or free services. See our free services guide for options.

The earlier, the better. Research shows early intervention (ages 2–6) produces the greatest gains due to brain plasticity. However, therapy at any age is beneficial. Do not wait for OAP, explore school-based and community options immediately after diagnosis.
