Yes you can. If you live in Ontario. It happened to my son. He was five and a half when his assessment was done.
In this blog I will try to explain how it happened and how it is happening to hundreds of children.
A lot of children, like my son, are being discharged from treatment because they are too autistic and not making enough progress. Others are not autistic enough, and sometimes do not even make it on waiting list--like my son's friend D. Some children--recently more than a thousand--stay on waiting list (like we did) for years.
My son was discharged because, according to highly trained specialists, he is not only autistic but also developmentally delayed.
According to Autism Society Canadaa
"Autism Spectrum Disorder is a neurological disorder resulting in developmental disability.
Behaviour, activities & interests"
Since my son is developmentally delayed and was not diagnosed with any other disorder, it was autism that caused the delay. He has severe delay since he is very low on the spectrum. He is, apparently, too autistic for treatment.
