Frequently asked questions

1

What is the wait time for ErinoakKids in Mississauga?

Ontario does not publish a comparable city-level or province-wide average OAP wait. Registration and active funding agreements are administrative statuses and are not proof of service receipt. Contact AccessOAP and local providers for current status and intake timelines.

2

Are there private autism therapists in Mississauga?

Mississauga has private ABA, speech, and occupational therapy clinics. Contact providers directly for current intake, credentials, goals, and itemized rates. There is no universal developmental window or automatic transition to OAP-funded service.

3

Where can I get an autism diagnosis in Mississauga?

ErinoakKids' Mississauga facility provides public autism assessments. Trillium Health Partners (THP) also offers developmental assessments. Private assessments are also available in Mississauga and the broader GTA — contact providers directly for current pricing and wait times.

What school supports are available in Peel District School Board?

Peel District School Board (PDSB) provides IEP services, IPRC determinations, and Educational Assistant support for autistic students.

Is the Ontario Autism Program underfunded?

Verified

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. This gap is the primary driver of the perpetual 91,974+ child waitlist.
