What is CAMH and what does it assess?
CAMH — the Centre for Addiction and Mental Health — is a large public mental health hospital in Toronto. On this site, CAMH appears in our adult services directory as a public option for adult autism assessment, alongside its mental health and crisis services. Like other hospital-based assessment services in Ontario, access runs through referral and intake rules that CAMH sets and can change.
A full adult autism assessment, wherever it happens, usually involves developmental history, diagnostic interview, and often standardized measures. The report matters as much as the diagnosis: if you need documentation for ODSP, the Disability Tax Credit, workplace accommodations, or adult developmental services, tell the assessor up front so the report addresses that purpose.
If mental health supports are needed while you wait for an assessment or after a diagnosis, CAMH and other Ontario services offer crisis and therapy routes — our urgent therapy answer page explains when to seek help now rather than waiting for a diagnostic appointment. And if the person being assessed is approaching 18, plan the transition early: aging out of the Ontario Autism Program means separate adult applications, and a diagnosis report is the entry point to most of them.
Confirm before you rely on this page. Intake criteria, referral pathways, and wait estimates at any hospital service change without notice. This page describes the route as this site has reported it — it is not a referral, and it is not CAMH's own program information. Contact CAMH directly for current requirements.
How long does the CAMH adult autism route take?
This site has reported that CAMH in Toronto offers public adult autism assessments with waits in the two-to-four-year range — while most private assessments by registered psychologists take four to twelve weeks. That gap is the practical decision most adults face: wait years for a public route, or pay privately.

Public or private: how should you choose?
- If cost is the barrier, the public route may be worth the wait — but ask CAMH for its current estimated wait before deciding.
- If you need the diagnosis sooner for work, benefits, or peace of mind, most Ontario adults go private.
Whichever route you choose, preparation shortens the process: gather school records and any childhood reports, write down the specific questions you want answered, and say what the report will be used for. Our adult diagnosis guide includes a full preparation walkthrough.
