World Autism Awareness Day has been held every year since 9 September 1989. It was designated by the United Nations General Assembly resolution "62/139. World Autism Awareness Day," adopted on 18 December 2007, proposed by Qatar, and supported by all member states. The resolution had four main components:
the establishment of 2 April as WAAD
participation of UN organizations, member states, NGOs and all private & public organizations in WAAD
raise awareness of autism on all levels in society
to ask the UN Secretary-General to deliver this message to member states and all other UN organs.
Autism Ontario celebrates World Autism Awareness Day by "Raising a Flag" for autism. Municipalities around Ontario raise a flag to raise awareness for autism in their region.
