The week after your child's autism diagnosis can feel overwhelming. This guide gives you a concrete action plan: what to do today, this week, this month, and while you wait for Ontario autism services.
Getting a diagnosis brings mixed emotions — relief at having answers, grief, fear about the future, and urgency. The urgency is real. In Ontario, the early intervention window (ages 0–6) is critical, and the system is slow. Here's exactly what to do, in order of priority.
Ask the assessor for:
Keep at least 3 copies. You'll need this report for: OAP registration, school IEP, disability tax credit, insurance claims, future service applications.
You don't have to do everything today. Your child is the same person they were before the diagnosis. The report is a key that opens doors to support. It's not a sentence.
This is the single most time-sensitive action. Every week you delay is a week added to your wait for core services.
How to register:
Or call AccessOAP: 1-833-425-2445 (Mon–Fri 8:30am–5pm)
Expect a confirmation email within 2–3 business days. Your wait time officially starts from your registration date, not the diagnosis date.

While waiting for core OAP services (which can take 5+ years), some families may be eligible for the OAP Childhood Budget — annual funding of $5,000–$35,000 based on family income. Contact AccessOAP (1-833-425-2445) to confirm current eligibility, as program details may change. The original "Interim One-Time Funding" program (2019–2021) is no longer available to new registrants.
Income thresholds (approximate — verify current amounts at AccessOAP.ca):
| Family Income | Approximate Annual Maximum |
|---|---|
| Lower income | Up to $35,000 |
| Middle income | Reduced amount |
| Higher income | Reduced or $5,000 minimum |
Send them a copy of the diagnostic report. This ensures:
If your child is school-aged (4+), call the school's principal and request:
If your child is pre-school aged, contact your local school board's Early Learning department about JK entry planning.
The Disability Tax Credit is worth $1,500–$3,500+ per year in federal and provincial tax savings. It's also the required gateway to the RDSP.
How to apply:
The retroactive period is 10 years — if your child was diagnosed years ago and you haven't claimed this, you may be owed significant refunds.
Once you have DTC approval, open an RDSP at any major bank. The government contributes:
A child whose RDSP is opened at age 3 and receives maximum grants/bonds could have $250,000+ by age 18 — even with no family contributions.
Review your extended health benefits for:
Submit any claims from the assessment while it's fresh.
While waiting for OAP, private therapy is the main route to services. Costs:
Use interim OAP funding to offset these costs. Prioritize speech and ABA for children under 6.
Ontario schools provide services that do not require OAP registration:
The school services are often underfunded and slow, but they're free and don't require OAP.
Autism Ontario (autismontario.com) has regional chapters across the province. They offer:
Membership is free. The parent-to-parent knowledge sharing is invaluable.
Several services are available right now:
