History of the Learning Disabilities Association of Ontario (LDAO)
The Learning Disabilities Association of Ontario (LDAO) has been a trusted leader in the field of learning disabilities for over six decades. Founded in the 1960s by a passionate group of parents and educators, LDAO began as a grassroots movement to raise awareness about learning disabilities and advocate for appropriate educational services. Since then, it has grown into a province-wide organization advancing equity, research, education, and support for individuals with learning disabilities (LDs) and co-occurring conditions such as ADHD.
From shaping public policy to developing innovative educator resources and empowering families and individuals, LDAO’s legacy is one of impact, inclusion, and systemic change.
Key Milestones
1960s

LDAO began as a grassroots movement led by parents and educators advocating for recognition, support, and appropriate educational services for children with learning disabilities in Ontario. This early activism laid the groundwork for systemic change in schools and communities.
1980

The Education Amendment Act (Bill 82) was enacted, requiring all Ontario school boards to provide special education programs and services—guaranteeing access to publicly funded education for students with disabilities.
1982

The Ministry of Education introduced Policy/Program Memorandum No. 8 (PPM 8), setting out requirements for the identification and program planning for students with learning disabilities and other exceptionalities.
2001

LDAO developed a new definition of learning disabilities through a province-wide consultation funded by the Ministry of Education, aligning the definition with evolving research and educational practices.
2014

A revised PPM 8 was released, incorporating significant updates based on current research and best practices. LDAO was a key contributor to the revision process, ensuring stronger supports for students with LDs.
2024

LDAO embarks on a renewed phase of strategic leadership, focused on advancing equity, strengthening community partnerships, and expanding supports across the lifespan — from school to home to the workplace. This period of growth builds on over sixty years of advocacy and innovation, positioning LDAO to meet evolving needs across education, employment, and policy systems.
Key Initatives
Throughout its history, LDAO has developed and supported a suite of initiatives that continue to expand the organization’s impact across the lifespan:
- LD@school and TA@l’école: Ministry-funded online platforms providing educators with research-informed strategies, webinars, and classroom-ready tools to support students with LDs.
- LD@home: A revitalized platform supported by Scotiabank, offering accessible webinars, navigation guides, and practical resources for families navigating the education system.
- LD@work: new initiative launched in 2025 to support adults with learning disabilities and ADHD in the workplace through tools for self-advocacy, employer guidance, and inclusive employment practices. Featured resources include Job-Fit, a tool for career exploration, and Some Assembly Required (SOAR), a workbook series designed to build self-awareness and transition skills in students and young adults.
