Our Vision

A proud Canada, where ALL are welcome, we embrace diversity and we value everyone equally.

Our Mission

To ensure equitable opportunities for all Canadians with Down syndrome.  This means, to make sure all Canadians with Down syndrome have the right supports to give them the same opportunities as everyone else.

Our History

The Down syndrome community in Canada and the CDSS have made great strides since our founding in 1987.

We have seen advances to medical care, which enhance and save the lives of people with Down syndrome; life expectancy has more than doubled.  Many people with Down syndrome live well into their 50s and 60s.

We have seen the benefits of early intervention programs, inclusion in school and work and the development of accessible resources for people with Down syndrome, families and the community.

Today, individuals with Down syndrome are going to post-secondary schools, working and getting married.  People with Down syndrome are now given the opportunity to be fully contributing members of society.

Despite the great advances made, much more needs to be done.  We need to ensure the inclusion of individuals with Down syndrome in their schools, communities and workplaces.  Your support will ensure this continues and allow us to speak for the 35,000 Canadians with Down syndrome.
