Frequently asked questions
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.
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.
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.
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.
Where the waitlist stands
