How long does autism diagnosis take in Ontario?

Before joining the OAP waitlist, Ontario diagnostic waitlists average **12–24 months** at public hospitals. [OAP] This pre-waitlist delay means total time from first concern to therapy often exceeds **5–7 years**, an invisible bottleneck in official statistics.

Windsor-Essex

Autism Diagnosis in Windsor-Essex

Families in Windsor often access services through the John McGivney Children's Centre (JMCC) or Hotel-Dieu Grace Healthcare (HDGH). Understanding the local landscape is key to reducing delays.

Windsor Snapshot
  • Public Hub: John McGivney Children's Centre (JMCC) and HDGH (Regional Children's Centre).
  • Wait Times: Public assessments face multi-year waits (local estimates: 12–24+ months; no provincial standard published).
Show all 4 factsShow fewer facts
  • Private Options: Limited local pool compared to GTA; some families travel to London for faster private access.
  • Cross-Border: US diagnosis (Detroit) is generally NOT accepted for OAP unless validated by an Ontario professional. Check carefully.
