Understanding Major Depressive Disorder
Major Depressive Disorder (MDD) is a clinical diagnosis characterized by the presence of a major depressive episode: at least two weeks of depressed mood or loss of interest, accompanied by at least five symptoms including significant weight change, sleep disturbance, psychomotor changes, fatigue, feelings of worthlessness or excessive guilt, difficulty concentrating, and in severe cases, recurrent thoughts of death or suicidal ideation. MDD can range from mild to severe. Severe MDD significantly impairs the ability to function in daily life and typically requires a combination of medication and therapy for effective management. Recurrent MDD – where depressive episodes occur repeatedly over time – is particularly common, and psychological therapy that builds relapse prevention skills is an especially important component of long-term care.

About Major Depressive Disorder Therapy
Why seek therapy?
People seek therapy for MDD when the depressive episode has become severe enough to significantly impair functioning – making working, maintaining relationships, or basic self-care difficult or impossible. Some come at the recommendation of a physician or psychiatrist alongside medication management. Others come when previous treatment approaches have not fully resolved the depression.
How therapy helps
Therapy for MDD uses CBT, Behavioural Activation, and Interpersonal Therapy as the primary evidence-based approaches. For recurrent MDD, Mindfulness-Based Cognitive Therapy (MBCT) has demonstrated significant effectiveness in reducing relapse risk. Coordination with prescribing physicians or psychiatrists is an important component of MDD treatment.
Benefits of Major Depressive Disorder Therapy
Comprehensive, Integrated Care
MDD often requires both psychological therapy and medical management. Our therapists coordinate with prescribing physicians and psychiatrists to ensure that all dimensions of care are addressed in an integrated way – producing better outcomes than either approach in isolation.
Relapse Prevention
Recurrent MDD is common, and relapse prevention is one of the most important goals of psychological treatment. MBCT and other approaches build specific skills for recognizing and responding to early warning signs of depressive relapse.
Addressing Severity With Appropriate Support
Severe MDD requires the level of therapeutic support appropriate to its severity. Our therapists are trained and experienced in working with severe and complex presentations – providing the depth and frequency of contact that serious depression requires.
MDD is serious. It deserves serious, specialized, evidence-based support.

Our Approach to Major Depressive Disorder Therapy
MDD therapy at Empire is tailored to the severity and complexity of the depressive presentation. For severe MDD, session frequency may be higher, safety assessment is more intensive, and coordination with medical providers is more active.
CBT and Behavioural Activation are the primary psychological frameworks, addressing the cognitive patterns and withdrawal that maintain the depression. For the most severe presentations, Behavioural Activation is often the most accessible early intervention.
Safety assessment and management is ongoing and thorough throughout treatment of MDD. Suicidal ideation, when present, is addressed directly and collaboratively – including safety planning and, where indicated, coordination with emergency services.
MBCT is introduced as an important component for clients with recurrent MDD. We coordinate actively with prescribing physicians and psychiatrists – ensuring that medication management and psychological therapy are working in concert.

Common Questions About Major Depressive Disorder Therapy
What is the difference between depression and Major Depressive Disorder?
MDD is the formal clinical diagnosis that describes a major depressive episode meeting specific diagnostic criteria. If you are experiencing a significant, impairing depressive episode, MDD may be the appropriate diagnosis regardless of the label you have been using.
I have had multiple depressive episodes. What can therapy do that medication has not?
Medication reduces symptoms during an active episode; therapy builds skills that reduce the risk of future episodes. MBCT in particular has demonstrated significant effectiveness in reducing relapse risk in people with recurrent MDD.
I have thoughts of suicide. Can I still access outpatient therapy?
Suicidal ideation in the context of MDD is a clinical priority that we assess carefully. Many people with suicidal thoughts can be safely and effectively treated on an outpatient basis. If you are in immediate danger, call 911 or go to the nearest emergency department.
Is a referral required?
No. You can book directly online or by calling (905) 962-2220.
History of Major Depressive Disorder Treatment
Evolution of Treatment
