Sensory regulation
Sensory processing differences can shape how a person responds to sound, touch, movement, light, and other input. This guide covers everyday strategies, Ontario OT pathways, and OAP funding.

Most people learn about 5 senses in school. Occupational therapists work with 8 sensory systems, all of which can be affected in autism.
Sensitivity to brightness, flickering lights, busy visual environments, or certain colours
Difficulty filtering background noise, distress from sudden or high-pitched sounds
Avoidance of light touch or certain textures on skin or in food
Heightened detection of odours that others may not notice; can trigger nausea or panic
Extreme selectivity based on taste, texture, or temperature of food
Located in the inner ear. Controls balance, spatial awareness, and tolerance for movement. Dysfunction leads to fear of swings or constant spinning and rocking.
Feedback from muscles and joints about where the body is in space. When dysregulated, children crash into things, use too much force, or seek deep pressure like tight hugs or weighted blankets.
Awareness of hunger, thirst, pain, heart rate, and the need to use the bathroom. Poor interoception is linked to emotional regulation difficulties and toileting challenges.
Winnie Dunn's Sensory Profile framework, the gold standard used by Ontario OTs, identifies four patterns based on neurological threshold and behavioural response.
High Threshold / Active Response
The nervous system needs more input than average to register sensations. These individuals are sensory cravers, constantly moving, touching everything, seeking intense input.
Common signs:
Low Threshold / Active Response
The nervous system is over-responsive and works hard to limit input. These individuals have strong reactions to sensations others barely notice.
Common signs:
Low Threshold / Passive Response
Notices everything, high registration, but responds with distraction or distress rather than active avoidance. Often described as easily bothered or irritable.
Common signs:
High Threshold / Passive Response
Slow to notice sensory information. May appear unaware of pain, mess, or temperature. Often perceived as in their own world or having a high pain tolerance.
Common signs:
Core Strategy
A sensory diet is a personalized, OT-designed schedule of sensory activities distributed throughout the day to keep the nervous system settled for learning, social contact and daily tasks. The term was coined by Patricia Wilbarger, OTR, and is the primary OT intervention for sensory processing differences.
Despite the name, it has nothing to do with food. Think of it as a daily exercise plan for the nervous system, providing the right type and amount of sensory input at the right times.
An OT conducts a formal evaluation using standardized tools (Sensory Profile 2, Sensory Processing Measure) plus observation and parent report to map your child's profile across all 8 senses.
The OT identifies which sensory systems are over-responsive, under-responsive, or dysregulated, and when during the day regulation is most challenging.
Activities are selected and timed to match your child's schedule. A school-aged child might have a proprioceptive activity before class, a movement break at recess, and deep pressure before homework.
The diet is carried out by parents, educational staff, and caregivers. The OT trains everyone and adjusts the plan as your child's needs evolve.
Regular OT check-ins (typically monthly or quarterly) review what's working, adjust activities, and ensure the diet keeps pace with development.
Sensory needs vary by context. Here are evidence-supported strategies for the three settings where autistic children spend most of their time.
Occupational therapists registered with the College of Occupational Therapists of Ontario (COTO) are the primary professionals for sensory assessment and intervention. Ontario families access OT services through the pathways below.
Ask your local children's treatment centre or school about occupational therapy support at school.
OT is covered under OAP funding. 5+ years for families registered in August 2021 (community-reported, Ontario Autism Coalition, July 2026) Interim one-time funding (an amount set by age band) can be used in the interim.
Registered OTs in Ontario commonly charge hourly rates in the low-to-mid hundreds of dollars (rates vary by region and provider). Many accept OAP funding, extended health benefits, or SSAH funding.
Ontario Autism Program funding can be used for occupational therapy, including sensory assessments and treatment. The funding tiers below apply to sensory needs.

A growing number of Ontario businesses and cultural venues offer sensory-friendly programming designed to reduce barriers for autistic individuals and their families.
Screenings take place every 4–6 weeks on Saturday mornings in a lights-up, sound-down environment. Check the local schedule before visiting.

Home Setup
A sensory space at home gives your child a predictable place to calm down and regulate. It needs little space or money. A corner of a bedroom or living room works well.
A quiet corner of a bedroom or a closet with the door removed work well. Avoid high-traffic areas. The space should feel safe and private.
Use string lights or a dimmable lamp instead of overhead lighting. A white noise machine or speaker with calming music reduces auditory distractions.
A weighted blanket at approximately 10% of body weight, a body sock, or a compression vest provides proprioceptive input. A cozy tent or canopy can give a sense of enclosure.
A small trampoline, balance board, or exercise ball can provide vestibular input. Even a swivel stool on a designated spinning spot on the floor counts.
Sensory bins (rice, kinetic sand), fidget tools, and chew tools address tactile and oral needs. Keep items organized so the space stays calming.
