Autism Diagnostic Services

Autism Diagnostic Services

Children’s Treatment Network (CTN) is serving as the lead for the Autism Spectrum Disorder (ASD) Diagnostic Hub in Central region.  Additional funding provided by the Ministry of Children and Youth Services (MCYS) will help provide additional diagnostic assessments until March 2018.  This will help more children and families receive the diagnostic assessments
they need.  Central Region includes:
•    Simcoe
•    York 
•    Dufferin
•    Halton
•    Peel
•    Waterloo
•    Wellington

CTN is working with partners in local communities to deliver diagnostic assessments. CTN, ErinoakKids, KidsAbility and Canadian Mental Health Association (CMHA) Guelph Wellington will provide services locally.

If your child’s name is already on a waitlist for an ASD diagnostic assessment with one of these agencies, there is no further action required.
If your child’s name is NOT on a waitlist for an ASD diagnostic assessment, please contact the agency listed for your local region to get information about these services. These services do require a physician referral.
