Sensory processing differences in autism range from mild sensitivities to profound dysregulation that affects daily function. Children may be hypersensitive (over-reactive), hyposensitive (under-reactive), or both, depending on the sensory system and context.
Sensory accommodations can be written into your child's IEP. The Ontario Human Rights Code requires schools to accommodate sensory needs as part of the duty to provide equal access to education.
Sensory break room or calm-down space
Designated quiet area for self-regulation during the school day.
Movement breaks
Scheduled activity breaks to meet proprioceptive and vestibular needs.
Noise-cancelling headphones
Permitted during loud activities, assemblies, or independent work.
Preferential seating
Away from high-traffic areas, windows, or noise sources.
Modified lighting
Avoid fluorescent flicker; allow hats or sunglasses for photosensitivity.
Sensory tools at desk
Fidget tools, resistance bands on chair legs, wiggle cushions.
Occupational therapists use sensory integration therapy to help autistic children process and respond to sensory input more adaptively. Treatment includes individualized sensory diets, therapeutic equipment activities, and environmental modification recommendations.
Learn About OT for AutismAutism Ontario provides sensory kits and resource guides for families, including fidget tools, visual supports, and sensory schedules.
Many Ontario science centres, museums, and theatres offer sensory-friendly hours with reduced lighting and sound. Check venue websites for schedules.
Cineplex offers sensory-friendly screenings with lower sound levels and house lights kept on. Check cineplex.com for local listings.
Stop Now And Plan (SNAP) Ontario offers parent training and resources for managing emotional and sensory dysregulation at home.
The OAP Childhood Budget can fund OT assessments, sensory therapy sessions, and clinically recommended sensory equipment. Always obtain a written recommendation from a COTO-registered OT before purchasing equipment through OAP funding.

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
