Behaviour Support for Autistic Children in Ontario

Understanding behaviour as communication. A neurodevelopment-affirming guide to behaviour support plans, finding a qualified BCBA, OAP funding, school supports, and ethical practice.

In brief

In short

  • Behaviour is communication: challenging behaviour serves a purpose (escape, attention, sensory, tangible)
  • Behaviour support plans (BSPs) must be based on a functional behaviour assessment (FBA)
Show all 6 facts
  • OAP funding covers FBAs, BSP development, caregiver coaching, and direct behaviour services
  • ABA is a science; Positive Behaviour Support (PBS) is a values-based framework within it
  • Find a BCBA through the BACB registry or ONTABA directory; ask about their approach to consent
  • Red flags: punishment-based, no FBA, compliance-only goals, ignoring child assent

Behaviour Is Communication

Every challenging behaviour serves a purpose. Before trying to change behaviour, we must first understand what the child is communicating. When we address the underlying need, the challenging behaviour often decreases naturally.

Who to call

School

Ontario's Education Act and PPM 141 set clear expectations for how schools respond to challenging behaviour, including strict limits on the use of restraint and seclusion.

IEP goals & PPM 141

Home / OAP

Behaviour analytic services are a core OAP-funded service. Families can access an FBA, a behaviour support plan, and caregiver coaching through an OAP-approved provider.

Crisis

If challenging behaviour has reached a crisis level and safety is at risk, get immediate support and next steps.

Crisis Support

Behaviour is not the problem. Behaviour is the symptom. Autistic children communicate through their behaviour, especially when they lack the language, skills, or regulatory capacity to express needs in other ways. Our job is to listen to what the behaviour is telling us, not to silence it.

Hitting, biting, or aggression

Possible functions:

  • Communicating pain, discomfort, or sensory overload
  • Requesting space or escape from demands
  • Expressing frustration when unable to communicate needs verbally

Elopement (running away)

Possible functions:

  • Escaping overwhelming sensory environments
  • Seeking preferred activities or locations
  • Responding to anxiety or fear

Meltdowns and shutdowns

Possible functions:

  • Neurological response to sensory, emotional, or cognitive overload
  • Accumulated stress exceeding coping capacity
  • Not a choice or deliberate behaviour

Self-injurious behaviour

Possible functions:

  • Communicating pain (headache, earache, GI distress)
  • Sensory seeking or self-regulation
  • Expression of extreme distress or anxiety

Demand avoidance / refusal

Possible functions:

  • Anxiety about unpredictability or perceived failure
  • Need for autonomy and control
  • Executive function challenges making task initiation difficult

Loud vocalizations or scripting

Possible functions:

  • Self-regulation and emotional processing
  • Sensory seeking (auditory input)
  • Communication attempt or expressing joy

The Four Functions of Behaviour

Behaviour analysis identifies four broad categories of behaviour function:

Escape / Avoidance

Behaviour to get away from something aversive

Attention / Connection

Behaviour to gain social interaction or response

Tangible / Access

Behaviour to obtain a preferred item or activity

Sensory / Automatic

Behaviour that provides internal sensory feedback
