Getting a Diagnosis in Childhood

Autism Ontario believes in the importance of early screening and diagnosis as they result in earlier and therefore more effective intervention. For a list of the indicators of autism, click here.
Parents are often given reassurance that the concerns they have about their child are unnecessary or unfounded, that the child is going through a "phase" or is just a little delayed for their age. Trust your instincts! If, after seeing your doctor and/or assessment team, you still have concerns, ask to be referred elsewhere for another opinion. Remember, parents, family members or other caregivers of children on the autism spectrum are usually first to notice delays in the child meeting the usual developmental milestones or differences in the ability to speak, make eye contact, play with other children or interact socially. 

If you think your child may have autism, there are two options to pursue a diagnostic assessment.


Option One:

Make an appointment with your family doctor or pediatrician.  Some family physicians and even pediatricians are not as familiar with ASD as one might hope or expect. If your family physician or pediatrician has only limited experience with ASD they may refer you to a specialist (e.g., a developmental pediatrician), or team of professionals, for a developmental assessment. A developmental assessment will look at your child's social, cognitive, communication, and motor skills. ASD is not diagnosed based on only one factor or symptom but when a combination of specific behaviours, communication delays, and/or developmental disabilities is confirmed. 

Option Two:

To access information regarding a diagnosis before the age of 18 through the new Ontario Autism Program, please contact the diagnostic hub in your area or your local Ministry of Ministry of Children, Community and Social Services Regional Office.

Remember, services in Ontario are changing. For more information on how to receive a diagnosis, access supports and services and get funding, before your child turns 18, please click here
