Established by Barbara Collier and Hazel Self in 2000, Communication Disabilities Access Canada (CDAC) is a Canadian, disability, non-profit organization, with charitable status. In partnership with people who have speech, language and communication disabilities, CDAC promotes communication accessibility to goods and services. Over the years, CDAC has developed a range of resources that have been used by thousands of people, including individuals who have disabilities that affect their communication, accessibility policy makers, human rights lawyers, researchers, and clinicians, as well as community businesses, organizations and government groups.

As of January 1, 2022, CDAC is an online resource only.  We now offer our resources and trainings at no charge to users, in order to advance accessibility to goods and services for people who have communication disabilities. We provide consultation on a fee-for-service basis.

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.
