If you're looking for mental health support in Ontario, you've probably come across several different titles: psychotherapist, psychologist, and psychiatrist. While all three professionals play important roles in mental health care, they have different education, training, and scopes of practice.
Understanding the difference can help you choose the right professional for your needs and feel more confident taking the first step toward better mental health.
In this guide, we'll explain what each profession does, when you might see each one, and how to determine which option is right for you.
What Is a Psychotherapist?
A psychotherapist is a regulated mental health professional who provides therapy to help individuals manage emotional, behavioural, and psychological challenges.
In Ontario, Registered Psychotherapists (RPs) are regulated by the College of Registered Psychotherapists of Ontario (CRPO). Their primary role is to help clients improve their mental well-being through evidence-based therapeutic approaches.
A psychotherapist can help with a wide variety of things, including:
Stress and burnout
Life transitions
Self-esteem issues
Grief and loss
Psychotherapists use a variety of therapeutic approaches, including:
Cognitive Behavioural Therapy (CBT)
Dialectical Behaviour Therapy (DBT)
Emotion-Focused Therapy (EFT)
Internal Family Systems (IFS)
Exposure and Response Prevention (ERP)
You are more likely to see a psychotherapy for on-going care. Sessions are often weekly or bi-weekly, especially at the start of care.
Can a Psychotherapist Diagnose Mental Health Conditions?
Registered Psychotherapists in Ontario do not provide formal psychological diagnoses. Instead, they assess your concerns, develop treatment goals, and provide therapy based on your symptoms and experiences. Many people seek therapy without needing a formal diagnosis.
What Is a Psychologist?
A psychologist is a highly trained mental health professional who has completed graduate-level education in psychology and is registered with the College of Psychologists and Behaviour Analysts of Ontario.
Psychologists provide psychotherapy, conduct psychological assessments, and diagnose mental health conditions.
They commonly work with individuals experiencing:
Anxiety disorders
Depression
ADHD
Autism Spectrum Disorder
Learning disabilities
Personality disorders
Trauma
Mood disorders
One of the biggest differences between a psychologist and a psychotherapist is that psychologists are qualified to perform comprehensive psychological assessments and provide formal diagnoses.
These assessments may include:
Cognitive testing
Personality assessments
Psychoeducational assessments
Diagnostic evaluations
Can Psychologists Prescribe Medication?
No, psychologists cannot prescribe medication in Ontario. If medication is recommended, they may collaborate with your family physician or a psychiatrist.
What Is a Psychiatrist?
A psychiatrist is a medical doctor who specializes in diagnosing, treating, and preventing mental illnesses.
Unlike psychologists and psychotherapists, psychiatrists attend medical school before completing specialized psychiatric training.
Because they are physicians, psychiatrists can:
Diagnose mental illnesses
Prescribe medication
Order laboratory tests
Rule out medical causes of symptoms
Develop medication treatment plans
Provide psychotherapy (although many focus primarily on medication management)
Psychiatrists may meet with people for short-term care to support with finding you the right medication for your mental health issues.
Psychiatrists often treat individuals on-going with more severe or complex mental health conditions, including:
Bipolar disorder
Schizophrenia
Severe depression
Psychosis
Treatment-resistant anxiety
Complex mood disorders
Many psychiatrists work alongside therapists to provide comprehensive care.
