Medically necessary consultations, diagnostic assessments, and medication management provided by a licensed Psychiatrist like Gregory are generally covered by Ontario Health Insurance Plan (OHIP) in ON when a referral from a family doctor is in place. Coverage for psychotherapy services provided by a psychiatrist can vary; some provinces cover it, while others may have limitations or it may be part of hospital-based programs.

It's crucial to discuss coverage specifics for therapy or any specialized treatments with Gregory's office or Ontario Health Insurance Plan (OHIP).

Do I need a referral to see Gregory, a Psychiatrist?

Yes, a referral from your family physician or another medical doctor (e.g., a pediatrician for child psychiatry, or an ER physician for urgent assessment) is almost always required to see a Psychiatrist such as Gregory for services covered by the provincial health plan. Mental health conditions often benefit from initial assessment by a primary care provider who can determine the need for specialist psychiatric care. The referral ensures coordinated care, appropriate triaging, and transfer of relevant medical history.

How is confidentiality handled in psychiatric care?

Confidentiality is a cornerstone of psychiatric care. Information you share with Dr. Gregory and his team is kept private and protected by law and professional ethics.

Dr. Gregory will typically discuss the limits of confidentiality with you at the beginning of your treatment.

What does a Psychiatrist like Gregory specialize in?

A Psychiatrist is a medical doctor (MD) who has completed specialized training in psychiatry, which is the branch of medicine focused on the diagnosis, treatment, and prevention of mental, emotional, and behavioral disorders. Unlike psychologists, psychiatrists can prescribe medication. He is a Psychiatrist who assesses, diagnoses, and treats mental, emotional, and behavioral disorders through medication, psychotherapy, or other interventions. Gregory is trained to assess both the mental and physical aspects of psychological problems and can provide a range of treatments including psychotherapy, medications, and sometimes other interventions like ECT or rTMS.

What is the main difference between a Psychiatrist like Gregory and a Psychologist?

The main difference is that a Psychiatrist, like Gregory, is a medical doctor (MD) who has completed medical school and then specialized residency training in psychiatry. Because they are physicians, psychiatrists can diagnose mental health conditions, prescribe and manage psychotropic medications, and provide various forms of psychotherapy. They can also order medical tests to rule out physical causes of psychiatric symptoms. A Psychologist typically has a doctoral degree (PhD or PsyD) in psychology and is trained in psychological assessment, diagnosis, and providing psychotherapy (talk therapy). Psychologists generally cannot prescribe medication in Canada, though they often work closely with psychiatrists or family doctors who do.

When should someone consider a referral to a Psychiatrist like Gregory?

A referral to a Psychiatrist like Dr. Gregory is typically considered when mental health symptoms are severe, persistent, complex, or not responding adequately to initial treatments provided by a family doctor or therapist. This can include: thoughts of suicide or self-harm; severe depression or mania; psychosis (hallucinations, delusions); debilitating anxiety or panic attacks; complex PTSD; severe OCD; suspected bipolar disorder or schizophrenia; treatment-resistant depression; or when medication management by a specialist is indicated. Psychiatrists are also consulted for diagnostic clarification and comprehensive treatment planning, especially for co-occurring conditions.
