Communication Disabilities Access Canada (CDAC) is a Canadian, disability, non-profit organization, with charitable status. CDAC promotes social justice, accessibility and inclusion for people who have speech, language and communication disabilities. Our online resources and training programs can be used, with appropriate citations to advance awareness of the accommodations and supports people may require in order to have equal access to goods, services and opportunities in their communities.


CDAC recognizes that the implications of COVID-19 are serious for people who have disabilities that affect their communication. To help people communicate about and during Covid-19, we have compiled some resources that may be useful. We will do our best to add to these resources throughout Covid-19. We also suggest that you follow us on social media for updates.

Communication as is an interactive, two-way process that includes both understanding and being understood. Communication involves a range of communication methods in face-to-face interactions, over the telephone, online and via reading and writing. Communication methods include speech, gestures, body language, writing, drawing, pictures, symbol and letter boards, speech-generating devices, as well as human services such as ASL/LSQ/ISL interpreting, captioning in real time, informal and formal communication assistance.

What we do

CDAC consults on communication accessibility policy and legislation, conducts research, and develops conceptual frameworks, resources and educational opportunities on a range of social justice, accessibility and human rights issues for people who have speech, language and communication disabilities.

People who have communication disabilities may have cerebral palsy, autism spectrum disorder, Down Syndrome, learning disability, intellectual disability, Fetal Alcohol Spectrum Disorder, traumatic brain injury, aphasia after a stroke, dementia, Amyotrophic Lateral Sclerosis (or ALS), Parkinson’s disease, or Multiple Sclerosis. We do not address the needs of people who are Deaf, deafened or have a significant hearing loss and who require sign language interpreting services as there are other organizations that do this.

Our online resources are used by many individuals and organizations to promote equal access to goods and services for people who have disabilities that affect their communication. Visitors to our website include people who have communication disabilities, family members, disability services, businesses and organizations, human rights agencies, government agencies, healthcare professionals, social service providers, police, legal and justice services, accessibility policy makers, legislators, and communication clinicians.

We do not provide clinical communication services. To find out about communication clinical services, please contact your provincial Speech-Language Pathologist and Audiology Association.
