Evidence supports autism screening and intervention commencing in the first 2 years of life — earlier identification directly enables earlier intervention during the highest neural plasticity window

A plain-language explanation of this stage and the next steps available to your family.
The Ontario Autism Program is built on a written autism diagnosis from a qualified professional. Without one yet, your job is to move an assessment forward and get organized. You do not need to understand the whole system today. A referral from your family doctor or paediatrician is usually the first step; public assessments can have long waits, and some families choose a private assessment. Either way, keep every letter and date — the paper trail starts now.
Ask for a referral
Ask your family doctor or paediatrician for an autism assessment referral, and ask — in writing — for the expected wait.
Note the referral date
Write down the date you asked and were referred. This is the first entry in your timeline.
Learn the two paths
Understand public (long wait, no cost) versus private (faster, paid) assessment so you can decide what fits your family.
Start your records
Open one folder for everything to come — referrals, reports, and dates.
I’m seeking an autism assessment for my child. Can you refer us, and can you tell me in writing roughly how long the wait is and what happens next?
