Eating Disorders
in Canada

In Canada, an estimated 2.7 million people are impacted; Approximately 1.4 million of these are youth. 


Eating disorders include Anorexia Nervosa (AN), Bulimia Nervosa (BN), Binge Eating Disorder (BED), Avoidance Restrictive Food Intake Disorder (ARFID) and Otherwise Specified Feeding and Eating Disorder (OSFED).

Eating disorders are serious but treatable mental illnesses that can affect anyone regardless of gender, age, racial and ethnic identity, sexual orientation or socio-economic background.


The COVID-19 pandemic has put a spotlight on this long-standing public health crisis, with a skyrocketing incidence and unprecedented spikes in hospital admissions and emergency room visits.

Too many people with an eating disorder are never diagnosed but suffer significant personal and family distress.  Only 10% of sufferers receive appropriate treatment, and an even smaller proportion access early intervention services.

The social and economic costs of untreated eating disorders are similar to those of depression and anxiety, with debilitating physical and mental health effects comparable to psychosis and schizophrenia.

While it is well documented that mental illnesses are a leading cause of premature death in Canada, it is less known that eating disorders have the highest overall mortality rate of any mental illness, with estimates between 10-15%. Suicide is the second leading cause of death (after cardiac disease) among those with AN; 20% of people with AN and 25-35% of people with BN may attempt suicide in their lifetime. For females aged 15-24 years old, the mortality rate associated with AN is 12 times greater than that ALL other causes of death combined.

Eating disorders are often accompanied by other mental illnesses; 50% of people with eating disorders meet the criteria for depression.

Younger Canadians are also increasingly engaging in dieting behaviour which may put them at risk of developing an eating disorder and other health-compromising conditions. In Canada, between 12% and 30% of girls and 9% and 25% of boys aged 10-14 report dieting to lose weight. Moreover, the incidence of eating disorders in Canadian children is estimated to be 2 to 4 times greater than Type 2 Diabetes.
