Adoptive parent not informed of child’s disabilities

My name is Dale Gosse and I am a single parent of three children. I adopted my youngest son two years ago. I was a foster parent for Batshaw Youth and Family Services in Quebec for many years until I moved here to Ontario years ago.
Chadley, my son, came to live with me a month after his second birthday. He is now 12.
My problem - or better yet, my frustration and disbelief - came as a result of an assessment I had done on my son for ADHD.
I knew my son was different early on. He couldn't sit still, was very agitated, and daily routines had to be repeated constantly to him during the course of a day.
After voicing my concerns to Batshaw, they decided to test him for memory, hearing, eyesight and Autism. Anyone could plainly see that Chad was not autistic, but they tested him anyway. All came back normal and as a foster parent I was given these results.
Finally after several conversations and meetings with the workers at Batshaw they finally tested him for ADHD.
I had to take time off work to bring him to several appointments in March 2003, where a thorough assessment was done on him. I was thrilled believing that once done, he and I would receive the help we needed to help him get along in today's world, and to grow into a healthy, responsible adult.
Months passed and I hadn't heard anything from Batshaw or the doctor.
I called several times and was informed that the assessment was ongoing and would take a while. Still Chadley received no treatment.
I moved to Ontario in June 2005. Ontario Services picked up our file and they continued to supervise us. I voiced my concerns to the school as well as Ontario Social Services and they arranged for another assessment for my son. his was done on April 15, 2007.
I received a detailed report by May 3.
To my disbelief and utter shock, right before my eyes was also the original assessment done on my son in Montreal in March 2003, and in that report (done when my son was five years old) it was clearly marked that my son was assessed for a mixed and receptive type of ADHD, Fetal Alcohol Syndrome and Cognitive Delay.
I had never seen this report before. I immediately called Batshaw and asked why I was never given a copy of the original assessment or even been spoken to about it.
I was informed that as a foster parent (even though adoption for Chadley was the plan from day one) I was not allowed to receive a copy or even to be informed about the results.
So this poor child could have been receiving help from the age of five.
They in my opinion didn't want to pay me the extra money for a "child with disability," and since I was going to adopt him, all costs would be put solely on me.
They buried a vital piece of information that could have helped Chadley and I cope with his condition.
Now that I have legally adopted Chadley, they tell me they are not responsible for any money due to Chadley or I.
What happened to social services helping the children and families they are responsible for?
My son could have been receiving help seven years ago.
Now at the age of 12, he and I and the rest of the family are struggling everyday to understand all that is connected with ADHD.
To say that I am angry would be the understatement of the century.
He and I have both been cheated in so many ways for so many years.
