Augmentative & Alternative Communication (AAC) Devices for Autism in Ontario

Types of AAC Systems

AAC systems fall into two categories: unaided (using the body, such as sign language or gestures) and aided (using external tools). Aided AAC ranges from low-tech options like picture boards and communication books to high-tech speech-generating devices (SGDs). Modern high-tech AAC primarily uses tablet-based apps such as Proloquo2Go, TouchChat, LAMP Words for Life, and Grid for iPad, which generate spoken output when the user selects symbols or types words.

Dedicated speech-generating devices from manufacturers like Tobii Dynavox and PRC-Saltillo offer specialized hardware with robust cases, eye-tracking capabilities, and switch access for individuals with motor challenges. The choice between tablet-based apps and dedicated devices depends on the individual's motor abilities, communication needs, cognitive level, and environmental demands.

In Ontario, CASLPO-registered speech-language pathologists conduct AAC assessments to determine the most appropriate system. This assessment evaluates language comprehension, motor abilities, visual skills, and communication environments to recommend a matched AAC solution. The assessment report is required for ADP funding applications.

Funding AAC in Ontario

Ontario offers multiple funding pathways for AAC devices. The Assistive Devices Program (ADP) covers up to 75% of approved speech-generating devices for Ontario residents with a valid health card. To access ADP funding, families need a prescription from a physician and an AAC assessment from an ADP-authorized speech-language pathologist.

OAP childhood budgets can supplement ADP funding to cover the remaining 25% of device costs, as well as fund the SLP assessment and ongoing AAC training sessions. Some private insurance plans also provide coverage for AAC devices prescribed by a physician. Families should coordinate between ADP, OAP, and private insurance to maximize coverage and minimize out-of-pocket costs.
