Occupational Therapy for Autism: What OTs Do and How to Access Services

Start with the goal

What is OT meant to change for your family?

An OT begins with a comprehensive assessment of the individual in context, observing how they function at home, school, and in the community, then builds a plan around a handful of functional goals. Pick the one closest to your situation to jump to what it typically involves.

Occupational therapy is a regulated health profession with a broad evidence base for improving functional participation in daily activities generally. Within autism specifically, evidence is strongest for goal-directed, individualized OT targeting named functional skills, and more mixed for sensory-only approaches used in isolation. Research suggests many autistic people experience sensory processing differences, which is why Sensory Integration (SI) is one of the most widely used autism-specific OT frameworks, but SI outcomes vary by individual and by how rigorously the approach is delivered. Read more on sensory integration therapy. OT should not be presented as a cure or as guaranteed to produce a specific outcome for any individual child.

Who delivers it

Credentials to check before you start

OTs in Ontario are regulated by the College of Occupational Therapists of Ontario (COTO). Registration with COTO is mandatory to practise and is the first thing to confirm. Autism-relevant OT work typically also involves additional, named training beyond base registration:

• COTO registration: searchable in the public member directory; confirms the practitioner is licensed and in good standing.
• Ayres Sensory Integration (ASI) training: a specific, certifiable course of study, not the same as general familiarity with sensory topics.
• Paediatric or autism-specific clinical experience: ask directly how much of their caseload is autistic clients, not paediatrics in general.
• Setting-specific scope:school board OTs, Children’s Treatment Centre OTs, and private-clinic OTs work under different mandates and caseload limits.

Cost, funding, and access

How OT is funded and accessed in Ontario

• OAP Childhood Budget: OT is an eligible funded expense. See 2026 OAP funding amounts.
• Children’s Treatment Centres (CTCs): publicly funded OT for children with complex needs, including autism; CTC waitlists are often long.
• School board OT: available to students with an identified OT need documented in their IEP, typically limited in session frequency.
• Private OT clinics: direct access, typically faster, at full cost unless covered by private insurance or the OAP Childhood Budget.
