Not published. Ontario publishes no comparable city-level wait or prevalence figure for Windsor. The figures above are provincial, and this page does not estimate a local one.
A diagnosis opens the funding route. School support runs on its own track and does not wait for it.
Children’s assessments start at Windsor Regional Hospital and Hôtel-Dieu Grace Regional Children's Centre. Adults are not covered by the children\u2019s hubs. Ask your family doctor about adult assessment options.

Windsor Regional Hospital provides public autism assessments. John McGivney Children's Centre (JMCC) also offers developmental services. Private assessments are also available in Windsor or London — contact providers directly for current pricing and wait times.
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.
