🧠 Why Families Choose Private Assessments
Many families in Ontario choose private diagnosis because:
- Early intervention (ages 2–6) is critical
- Waiting years can delay therapy and development
- A diagnosis is required to access funding like OAP
In some cases, families do both:
👉 Get a private diagnosis quickly
👉 Stay on the public waitlist for a more comprehensive evaluation later
💡 What Happens After Diagnosis?
A formal autism diagnosis in Ontario allows access to:
- Ontario Autism Program (OAP) funding
- School supports (IEP, accommodations)
- Disability Tax Credit (DTC)
- Therapy services (private or funded)
⚠️ Hidden Costs to Consider
Even after diagnosis, families may face additional costs:
- Therapy (if not fully funded)
- Psychological or developmental follow-ups
- Travel to assessment centers
- Time off work for appointments
📍 Key Takeaway
- If budget is limited → Public (free but slow)
- If time is critical → Private (expensive but fast)
👉 The real decision is:
“Can we afford to wait?”
