What are the leading causes of death in Canada?

Cancer and heart disease are still the leading causes of death across Canada, but COVID-19 comes in at the third top spot.

Every year, Statistics Canada records the number of deaths across Canada — and the major diseases that Canadians are dying from. We combed through this data to find the leading causes of death, as well as which conditions were different among men and women.

The 10 leading causes of death in Canada

Statistics Canada released its 2020 mortality data. Of the 307,205 Canadians who died, the top two causes of death were the same as in previous years – cancer and heart disease (killing 80,973 and 53,704 people, respectively).

A notable difference between Statcan’s 2019 and 2020 data is that suicide and kidney disease made the list of the top 10 leading causes of death in 2019, but were replaced by COVID-19 and chronic liver disease in 2020.

The other top 10 leading causes of death in 2020 stayed relatively the same compared to 2018 and 2019.

How did COVID-19 impact the leading causes of death in Canada?

COVID-19 became the third highest cause of death in Canada in 2020, with a death rate of 16,151 people in total. COVID-19 was the fourth leading cause of death for men and the third leading cause of death for women.

The top 10 leading causes of death for men

These were the leading causes of death among Canadian men. Interestingly, the number of deaths caused by cerebrovascular diseases outranked the number of deaths caused by chronic lower respiratory diseases, unlike in 2019 where the situation was reversed. Other than that and the introduction of COVID-19, the leading causes of death for Canadian men stayed relatively the same from 2019 to 2020.

How do the leading causes of death compare for men and women?

Here are a few key differences between the leading causes of death for men vs. women in Canada.

  • COVID death rate. COVID-19 killed 549 more Canadian women than men in 2020.
  • Top 2 causes of death. The top 2 causes of death in 2020 for both men and women were cancer and heart disease.
  • Cancer killed more men than women. Cancer killed 4,741 more men than women in the year 2020.

  • Suicide and liver disease are top causes of death for men. While most of the top 10 causes of death impacted both men and women, suicide and liver disease were two that appeared on the top 10 list for men, but not women.
  • Alzheimer’s and kidney disease are top causes of death for women. Alzheimer’s and kidney disease appear on the list of the top 10 causes of death for women, but do not make the top 10 list for men.

What’s the average age of death in Canada?

With all this talk of death, it’s important to keep in mind that the average age of death in Canada is still relatively high. The average life expectancy is 79.82 years for men and 84.11 years for women. While there are many factors that can impact your life expectancy, like your environment and family history, the majority of Canadians live long lives.

How we collected this data

To learn about the leading causes of death among Canadians, we turned to the Statistics Canada mortality data. Statistics Canada analyzes deaths and diseases each year, with the most recent data focused on 2020. We’ll update this page as new data is released.

How do life insurance companies assess your life expectancy?

The general rule is that the healthier you are, the less you’ll have to pay for life insurance. Each insurance provider has its own underwriting process. As such, some put more weight on certain evaluation factors over others. Take a look at a few points that will be assessed:

  • Age. How old you are plays possibly the biggest role in determining your premiums. The younger you are, the lower your premiums will typically be.
  • Gender. Women typically end up with lower premiums than men, mostly due to women having a higher average life expectancy.
  • Certain health indicators. When a medical exam or medical questions are involved, your weight, height, blood pressure and any history of major diseases or medical conditions help determine your premiums.
  • Family health history. Major health conditions and diseases in your immediate family are likely taken into account. Cancer, cardiac arrest, kidney disease and stroke are among what may affect your premiums.
  • Smoking. General frequency, and the last time you smoked before your medical exam, will likely be considered when determining how much you’ll pay in premiums.
  • Substance use. Alcohol or drug use that has resulted in doctor-mandated rehabilitation and illegal substance abuse are likely to increase your premiums. Life insurance companies generally believe that if you avoid or moderate these substances, you’ll be prevented from getting their associated diseases.
  • High-risk occupations and hobbies. Certain occupations and hobbies are considered riskier than others. Being a lumberjack is objectively more dangerous than working in accounting. Likewise, a skydiving hobby will earn your application more scrutiny than needlepoint.
  • Driving and criminal records. Several tickets within a short period of time, DUIs and arrests can contribute to what your policy costs.
