Has the government cleared the autism backlog?

Verified

No. Government claims of "clearing the backlog" refer only to administrative invitations, not actual service delivery. While 91,974 children are registered, 71,263 still lack funding for clinical therapy. May 2026 data confirms that only 22.5% of children have accessed core services.

How long does autism diagnosis take in Ontario?

Verified

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