Autism does not rule out anxiety, depression, trauma, or another mental health concern. Bring a clear record of changes in mood, sleep, safety, daily function, and communication to a qualified clinician.

Clinicians incorrectly attribute mental health symptoms to autism itself. Depression, for example, may be dismissed as "autistic withdrawal" rather than recognized and treated as a separate condition.
Many conditions share features with autism: social withdrawal (depression), repetitive behaviours (OCD), inattention (ADHD). Teasing apart which symptoms belong to which diagnosis requires specialists with dual expertise.
Standard mental health assessments rely on verbal self-report. Autistic people may have alexithymia (difficulty identifying emotions), atypical pain/distress expression, or communication differences that standard tools miss.

Mental health conditions can co-occur with autism. A qualified clinician can assess concerns and discuss support options.
OHIP covers psychiatry appointments and physician-referred mental health services, but does not cover psychotherapy delivered by psychologists or social workers directly. Many autistic people access OHIP-covered services through CAMH, regional CMHO agencies, and community mental health centres. Psychotherapy funded through Ontario's Structured Psychotherapy (OSP) program is available via primary care referral at no cost and is autism-accessible.
Yes. OAP Core Clinical Services funding ($6,600–$65,000/year) can fund mental health-related services when autism is the primary diagnosis and the treatment addresses autism-related goals. This includes ABA therapy that addresses anxiety and emotional regulation, occupational therapy for sensory and mood regulation, and social skills groups addressing social anxiety. Standalone psychiatric medication management is generally not covered by OAP.
Diagnostic overshadowing occurs when mental health symptoms in an autistic person are incorrectly attributed to autism itself rather than recognized as a separate, treatable condition. For example, a clinician may assume withdrawal and lack of motivation are autism traits rather than recognizing clinical depression. This leads to delayed or absent treatment for co-occurring mental health conditions. Families should advocate for full mental health assessments even when autism is already diagnosed.
The 988 Suicide Crisis Helpline (call or text 988) is available nationally. 211 Ontario provides referrals to local services. Contact local providers directly to ask about their crisis services and availability.
Ontario has a significant service gap at age 18. Children's mental health agencies stop serving clients at 18, while adult mental health services are under-resourced and rarely autism-specialized. OAP services also end at 18. Planning the transition at age 16 is recommended: ask your CMHO agency about their adult transition pathways, request a warm handoff to adult psychiatry, and register with CAMH's adult autism services waitlist early.
Ontario has several culturally responsive mental health programs that also serve autistic clients. CAMH's Access CAMH program provides intake across diverse communities. The Black Youth Helpline (1-833-294-8650) and Arab Community Centre of Toronto provide culturally specific support. When seeking autism-informed mental health care, request a clinician familiar with both your cultural background and neurodevelopmental differences. Advocacy Ontario can assist with navigation.
Psychiatrists are medical doctors who can prescribe medication and are OHIP-covered. They are better suited for medication management of depression, anxiety, or OCD in autistic patients. Psychologists hold doctoral-level degrees and provide psychological assessments and psychotherapy, costs are $200-$300 an hour and not OHIP-covered unless through specific programs. For autistic individuals, a team approach (psychiatrist + psychologist) is ideal. Some CMHO agencies offer both under one roof.
Getting the right mental health support starts with the right diagnosis. If you haven't received an autism assessment yet, that's the first step. If you have, explore what you can access now while waiting for other services.
