Studying the statistics

Cancer is still the top killer of firefighters in Canada while mental health is an increasing concern, according to nationwide insurance claims data.

A 2019 analysis of new claims data from the Association Workers’ Compensation Boards of Canada (AWCBC) has revealed a notable change in what is killing and harming Canadian firefighters after just two years.

The analysis compared a more recent 10-year period of Canadian fatality and time-loss claims data with the results of a study of 2006-2015 AWCBC and WorkSafe BC data and additional research, reported in Determinants of Injury and Death in Canadian Firefighters: A Case for a National Firefighter Wellness Surveillance System.That February 2018 study, conducted by the University of the Fraser Valley and the British Columbia Injury Research and Prevention Unit, reflected more than a year of work by a team of Canadian health professionals, researchers, academics and fire service leaders: Rachel Ramsden, Jennifer Smith, Kate Turcotte, Len Garis, Dr. Kenneth Kunz, Dr. Paul Maxim, Larry Thomas and Dr. Ian Pike.

The new analysis, conducted by Surrey Fire Services in British Columbia, compared the 2006-2015 results (Cohort 1) with updated data from 2008-2017 (Cohort 2).


When it comes to firefighter fatalities, the following changes were observed:

  • A 21-per-cent increase in overall on-duty firefighter fatalities between Cohort 1 (568 fatalities) and Cohort 2 (687 fatalities).
  • A three-per-cent increase in the percentage of cancer deaths between Cohort 1 (85 per cent) and Cohort 2 (88 per cent), equating to a 24-per-cent increase in the rate per 100,000 firefighters from Cohort 1 (49.5) to Cohort 2 (61.5).
  • A 23-per-cent decrease in the percentage of traumatic injury deaths, the second top killer of firefighters, from Cohort 1 (six per cent) to Cohort 2 (4.6 per cent). This equated to an 8.6-per-cent decrease in the rate per 100,000 firefighters from Cohort 1 (3.5) to Cohort 2 (3.3).
  • A 14-per-cent decrease in cardiovascular disease deaths, the third top killer of on-duty firefighters, from Cohort 1 (4.9 per cent ) to Cohort 2 (4.2 per cent). This equated to a 3.6-per-cent increase in the rate per 100,000 firefighters from Cohort 1 (2.8) to Cohort 2 (3.9).

“The new data confirms that not only are more Canadian firefighters dying during their careers, but cancer is still the leading cause of fatalities – and rising,” noted Chris Biantoro, the strategic planning analyst at Surrey Fire Services who conducted the analysis. “We can also detect a rising incidence of mental-health issues among firefighters, leading to more time off from work.”

In terms of time-loss claims – reflecting injuries and other issues that prevent firefighters from working – these changes were noted:

  • A 3.8-per-cent decrease in overall firefighter time-loss claims.
  • A 1.7-per-cent decrease in traumatic injuries, still the top cause of time-loss claims, from Cohort 1 (89.9 per cent) to Cohort 2 (88.3 per cent).
  • An 81-per-cent increase in mental-health claims, now the second top cause of time-loss claims, from Cohort 1 (1.6 per cent) to Cohort 2 (2.9 per cent).
  • An 8.7-per-cent decrease in musculoskeletal system and connective tissue injuries, the third top cause of time-loss claims, from Cohort 1 (2.3 per cent) to Cohort 2 (2.1 per cent).

It should be noted that the data used for the analysis was limited to show the aggregate number of claims not less than four, to protect the confidentiality of claimants, and random allocation was then applied to the suppressed numbers. For that reason, the actual numbers presented in the analysis may not reflect the actual numbers from the data or the previous analysis.

Even so, the new analysis reflects the trends identified in the 2018 study, including rising incidences of cancer and mental-health issues, and decreasing incidences of cardiovascular disease, which was once the leading cause of firefighter death.

As noted in the earlier study, firefighters die of cancer at two to three times the rate of the general population (depending on age) – even though firefighters tend to lead healthier lifestyles as a requirement of their work. This additional risk comes from their exposure to concentrated carcinogens in the air, soot and tar at a fire ground. Even after using personal protective gear, many firefighters report smelling like smoke or burning plastic for days after a fire.

Mental-health issues – such as anxiety, post-traumatic stress disorder and depression – were also pointed out as a rising concern in the earlier data, and that is borne out by the updated figures.

Building on the earlier research, the new analysis has implications for the 100,000-plus volunteer and career firefighters across Canada, as well as those abroad, including approximately 1.2 million in the United States.

Bolstered by the newer data, the 2018 study’s recommendations still hold true. In particular, it had called for a national firefighter wellness surveillance system to address the escalating cancer and other identified risks.

Although existing workplace claims systems collect considerable data and information, they lack the details and specifics that would allow the development of targeted surveillance, prevention, wellness and ongoing research programs. The study recommended development of a dedicated firefighter health surveillance model to monitor health trends and patterns and provide the information necessary to support future research, and develop timely and responsive interventions that will lead to healthier and longer lives for Canadian firefighters.

At the local level, the study also recommended that fire departments take proactive steps to address the highest risks to firefighter health, including mental health issues.
