  • In 2009 there were 3,890 suicides in Canada, a rate of 11.5 per 100,000 people.
  • The suicide rate for males was three times higher than the rate for females (17.9 versus 5.3 per 100,000).
  • Although suicide deaths affect almost all age groups, those aged 40 to 59 had the highest rates.
  • Married people had a lower suicide rate than those who were single, divorced or widowed.

Suicide is a major cause of premature and preventable death. It is estimated, that in 2009 alone, there were about 100,000 years of potential life lost to Canadians under the age of 75 as a result of suicides.

Research shows that mental illness is the most important risk factor for suicide; and that more than 90% of people who commit suicide have a mental or addictive disorder.1,2 Depression is the most common illness among those who die from suicide, with approximately 60% suffering from this condition.3,4 No single determinant, including mental illness, is enough on its own to cause a suicide. Rather, suicide typically results from the interaction of many factors, for example: mental illness, marital breakdown, financial hardship, deteriorating physical health, a major loss, or a lack of social support.5

This article presents the latest statistics on suicide,6 looking primarily at trends and variations by sex, age and marital status. The main source of data is the Canadian Vital Statistics Death Database.7

The Canadian Vital Statistics Death Database collects demographic and cause of death information annually from all provincial and territorial vital statistics registries on all deaths in Canada.20 Suicide data from this source are somewhat under-reported due to the difficult nature of classifying suicide and the time lag in determining this as the cause of death, which may vary from year to year and from one region to another.17,18,19,21

Males commit suicide at a higher rate than females

In 2009, there were approximately 238,000 deaths in Canada, of which 3,890 were attributed to suicides. This resulted in a suicide rate of 11.5 deaths per 100,000 people. During that year, a total of 2,989 males committed suicide (17.9 deaths per 100,000) compared to 901 females (5.3 deaths per 100,000). As these data show, males were three times more likely to commit suicide than females.

The much higher rate of male suicide is a long-term pattern in Canada. At all points in time over the past 60 years, males have had higher rates of suicide than females (Chart 1). For both sexes, suicide rates remained fairly stable in the 1950s then steadily rose between the 1960s and 1980s where it peaked in 1983 at 15.1 per 100,000 (age-standardized rate).8 Since then, rates have dropped to 10.7 deaths per 100,000 in 2009. While male suicide rates have been generally decreasing since 1999, female rates appear to have stabilized.

Deaths by suicide, it should be noted, reflect only a small percentage of suicide attempts. It is estimated that for every completed suicide there are as many as 20 attempts.9Although males are more likely to die from suicide, females are three to four times more likely to attempt it.10,11 Furthermore, females are hospitalized for attempted suicide 1.5 times more frequently than males.12

This discrepancy may be due to the fact that females tend to use less fatal methods,5 such as poisoning—the most common cause of self-harm hospital admissions—whereas males tend to use more violent methods such as hanging and firearms (Chart 2).12

Methods of suicide vary by sex and age

Over the past ten years, the most common method of suicide in Canada has been hanging (44%), which includes strangulation and suffocation; followed by poisoning (25%) and firearm use (16%).

Males were most likely to commit suicide by hanging (46%) while females most often died by poisoning (42%) (Chart 2). Males (20%) were far more likely to use firearms than females (3%).

Even though hanging has been the most common method of suicide, it declined with age; 55% of 15 to 39 year-olds died as a result of hanging, compared with 30% of those aged 60 and older. The percentage of suicides involving a firearm, on the other hand, increased with age; 12% of 15 to 39 used a firearm, compared with 26% of those aged 60 and older (Chart 3).

Variability in the method also increased with age. While most young people (15 to 39 years old) committed suicide by hanging, there was greater variability in the method of those aged 40 and older.

The highest rates of suicide occur during mid-life

When suicide deaths are examined across age groups, persons aged 40 to 59 have the highest rates (Chart 4). Forty-five percent of all suicides in 2009 (1,769 out of a total of 3,890) were in this age group, compared with 35% for those aged 15 to 39, and 19% for those over the age of 60. This has been a persistent trend in Canada, yet contrasts with suicide trends in many other countries where the rate of suicide tends to increase with age.2,9

Suicide is a leading cause of death in young people

Suicide is one of the leading causes of death for people of all ages. In 2009, it ranked as the ninth leading cause of death in Canada. Among those aged 15 to 34, suicide was the second leading cause of death, preceded only by accidents (unintentional injuries).

Because they do not generally die from natural causes, suicide represents a relatively large percentage of all deaths for younger age groups (15 to 34). After the age of 35, suicides as a proportion of all deaths start to decline as other causes become more common (Chart 5).

In 2009, 202 individuals aged 15 to 19 committed suicide. This represented almost a quarter (23%) of all deaths in this age group, up from 9% in 1974. The relatively higher proportion of suicide deaths for this age group is due to the decline in overall mortality rates, a trend driven mainly by declines in accidental deaths which continue to be the leading cause of death for 15 to 19 year olds. Despite the progress in reducing deaths from accidents, however, suicide rates for this age group did not change significantly during this period (Chart 6).

Married people are the least likely to commit suicide

For both men and women, married people were the least likely group to commit suicide. Single (never married) people were the most likely, at a rate 3.3 times higher, followed by widowed and divorced (Chart 7). Single men were much more likely to die from suicide than those who were married. Among women, widows had highest rates of suicide. The social support and companionship provided by marriage may be important conditions that help decrease the probability of suicide.13

The differences according to marital status may partially account for the higher rate of suicide amongst people aged 40 to 59 as people transition from married to divorced and widowed. While marriage provides a protective effect across all age groups, suicide rates among the divorced and widowed are particularly high for those aged 40 to 59 years. Divorced people in this age group have a suicide rate 1.7 times higher than divorced people of other ages.

Widowhood also appears to have a greater effect on the middle-aged; the suicide rate in the widowed aged 40 to 59 years is 2.1 times higher than for the widowed 60 and older. Finally, single people 40 to 59 have double the suicide rates compared to singles of other ages.

Previous research has found an association between the break-up of a marriage (or co-habiting relationship) and increased risk of depression, the most common mental health disorder amongst people who commit suicide.14 Given the relationship between marital breakdown and depression, and the association between depression and suicide, suicide rates were plotted with the divorce rates for the period 1950-2008. The trend lines show a similar pattern (Chart 8). This finding is consistent with other studies which have found correlations between suicide and divorce in Canada.15,16

During the 1950s, divorce and suicide rates were fairly stable, but both began to rise during the 1960s. In 1968, Parliament passed the Divorce Act which established a federal-level divorce law. In the following year the divorce rate increased by 128%, and as Chart 8 shows, suicide rates moved in the same direction. In 1986 the Divorce Act was amended, reducing waiting times from three years of separation to one. This resulted in 1987 having the highest rate of divorce in Canadian history. This increase in divorces was paralleled by an increase in suicide rates. After the 1987 spike in the divorce rate, both divorce and suicide rates have seen a similar decline.


Using vital statistics to explore different aspects of suicide in Canada has shown that males are far more likely to commit suicide than females. Looking at suicides by age group for both sexes, the highest suicide rates were found in those aged 40 to 59. However, suicide ranks second as a leading cause of death for people aged 15 to 34. Looking at suicide deaths by marital status revealed significantly lower rates for married people, and there is a compelling parallel between historical trends for suicide and divorce. This finding would benefit from further research.
