Is the Ontario Autism Program underfunded?
Yes. The Financial Accountability Office (FAO) determined that **$1.35 billion annually** is needed to serve all registered children at 2018-19 service levels. The 2026-27 Ontario Budget allocated **$965 million**, leaving an estimated **$385M+ annual shortfall**. [FAO, Ontario Budget 2026] This gap is the primary driver of the perpetual 89,799+ child waitlist.

Mississauga families attend schools under the Peel District School Board. Understanding your child's educational rights, including IEPs (Individual Education Plans) and IPRCs, is vital while waiting for clinical services.
IEP (Individual Education Plan)
A legal document outlining your child's learning needs, supports, and goals within the Ontario curriculum.
69,166 children are waiting. It takes 2 minutes to demand change.
Your MPP represents Mississauga in Queen's Park. A personal email from a constituent carries far more weight than a petition. Let them know this crisis is happening in their riding.
ErinoakKids is the lead OAP agency for Peel, Halton, and Dufferin. While assessment wait times vary, accessing OAP-funded Core Clinical Services through ErinoakKids is subject to the provincial 5+ year waitlist. ErinoakKids also runs Urgent Response Services for Peel families in immediate need.
Yes, Mississauga has a growing network of private ABA, speech, and occupational therapy clinics. Private ABA rates typically run $60–$150/hour. Many parents on the OAP waitlist pay privately during the critical 0–6 developmental window, then transition to OAP-funded services when their invitation arrives.
ErinoakKids' Mississauga facility provides public autism assessments with wait times of 12–24 months. Trillium Health Partners (THP) also offers developmental assessments. Private assessments in Mississauga and the broader GTA cost $2,500–$4,000 with 3–8 week waits — many Peel families travel to Toronto for private options.
Peel District School Board (PDSB) provides IEP services, IPRC determinations, and Educational Assistant support for autistic students. PDSB operates dedicated ASD classes at select schools and integrated support at others. Parents can request an in-school team meeting to initiate assessment for special education services.
