The LDAC is a national, non-profit, volunteer-based organization founded in 1963 with the mission of representing children and adults with learning disabilities, and those who support them. LDAC activities include providing information and advocacy in the areas of prevention - e.g., protecting the developing brain, early identification, assessment, education, intervention, social interaction, coping skills, family support, transitions, employment, and justice. LDAC represents these issues to various levels of government and other agencies, and provides information and support to persons with learning disabilities, parents, and professionals. LDAC has published a number of manuals, guides, self-help and reference books to meet growing needs, and has developed screening and teaching tools to increase the literacy skills of adults with learning disabilities.
Affiliated Learning Disabilities Associations exist in each Canadian province and two territories, which extend to a network of more than 55 chapters across the country; all maintaining the shared mission. LDAC is governed by a Board of Directors composed of 17 members appointed by each of the ten provincial and two territorial Associations as well as members at large. It also has a Professional Advisory Committee comprised of 15 experts in the field of learning disabilities.
