Study identifies causes of officer injury and death

July 11, 2019  By Len Garis and Irwin Cohen

More research is needed to make police work safer, according to a Canadian study that showed officers under the age of 40 – and particularly males – are at higher risk of injury or death than their older counterparts.

The police are the only 24/7 first responder agency present in every Canadian community. Police officers are routinely placed in harm’s way as they respond to all types of calls for service, attend emergency situations, provide first aid and medical assistance, interact with offenders, deal with people suffering from a range of mental health issues and addictions, and address a variety of crime and social issues in their community.

Given this, officers face a higher risk of physical and psychological injuries, based on the frequency and intensity of their interactions with the public, the physical nature of their duties, the requirement to spend long periods of time in their vehicles or engaged in stressful activities related to dangerous or traumatic events, and the nature of shift work.

Released in August 2018 by the Centre for Public Safety and Criminal Justice Research at University of the Fraser Valley in British Columbia, the study Determinants of Injury and Death in Canadian Police Officers, by Irwin Cohen and myself, reviewed 10 years of workplace claims data to examine the nature and causes of injuries and fatalities among Canadian police officers.


The study highlighted areas that may require additional attention to ensure police officers remain physically and mentally safe and well throughout and after their policing careers.

In particular, the study pinpointed violence and traffic accidents as the most common factors in officer fatalities, and noted that officers who were injured or die were most often younger males. When female officers were the victims of a fatality, they tended to be even younger.

“Although there are inherent risks to police work, it’s important that we never take officer health and safety for granted,” commented Chief Const. Adam Palmer, president of the Canadian Association of Chiefs of Police. “Canadian police leaders should support new research and take note of studies, like this one, that shed light on potential opportunities to make policing safer.”

As of 2015, Canada had about 68,700 police officers, with about 58,000 (84 per cent) of those located in the four provinces examined for the study (due to the availability of data); Ontario (26,205 officers), Quebec (16,012), B.C. (8,672) and Alberta (7,155).

According to data from the Association of Workers’ Compensation Boards of Canada, those four provinces produced 92 per cent or 20,598 of the 222,394 accepted injury and fatality claims across Canada between 2006 and 2015. Included in that figure were 45 fatalities – a rate of 0.7 fatalities per 1,000 officers.

Over time, the risk to officers has changed. Over the 10-year period, claims related to contact with objects and equipment dropped 15 per cent, traffic accidents dropped 34 per cent and fires and explosions dropped 44 per cent, while violent acts also dropped by 10 per cent. At the same time, claims related to exposure to harmful substances increased by 39 per cent, and falls increased by 9 per cent.

The study did note a downward trend in the overall number of accepted time-loss claims, pointing to changes in police health and wellness policies as a possible cause.

While the percentage of officers increased by 10 per cent from 2006 to 2015, the number of accepted time-loss claims decreased by 9 per cent. As well, the rate of accepted claims per 1,000 officers dropped from a high of 37 in 2006 to a low of 30.6 in 2015 – a 17 per cent decline. The last year of the study, 2015, had the fewest number as well as the lowest rate per 1,000 of time-loss claims from throughout the 10-year period.

When only traumatic injuries or disorders are considered, accepted claims reduced from a high of 33.2 per 1,000 officers in 2006 to a low of 27 per 1,000 in 2015 – a 19 per cent decline.

The gender disparity is also of interest when considering the overall decline in claims. While overall claims by male officers dropped 12.8 per cent from 2006 to 2015, claims by female officers only dropped 1.2 per cent.

Differences in claims due to geography, change over time, and injuries to specific body parts are also considered in the study. It is important to note the data used in the report came from five distinct databases, each looking at one aspect of the context of fatality and accepted time-loss claims. The authors pulled together the aggregate data from the various databases to present a complete picture.

Key study findings:

  • About 80 per cent of Canadian officers are men and, on the whole, men filed a similar percentage of the total accepted time-loss claims. However, men were overrepresented in fatalities, making up about 89 per cent of police officer fatalities from 2006 to 2015.
  • The most common age for male officer fatalities was 30 to 39 years old (45 per cent). All of the female fatalities were for police officers between 20 and 29 years old.
  • When both injury and fatalities are considered, 38 per cent of male time-loss claims were for those under the age of 35, and 48 per cent of female time-loss claims were for those under the age of 35 years old.
  • The most common cause (89 per cent) of overall time-loss claims was a traumatic injury or disorder, most often related to either a violent act or traffic incident involving either a vehicle or pedestrian.
  • When only fatality claims are considered, violence and traffic accidents were the most common precipitating events, followed by exposure to harmful substances, and bodily reaction or exertion. Leading sources of injuries resulting in death were vehicles (36 per cent) and a person, plant, animal, or mineral (22 per cent).
  • Sources of injury changed over the years and some varied significantly based on gender. Over the 10-year timeframe, the incidence of chemicals and chemical products as a source for female time loss claims doubled, while dropping 26 per cent for males. Containers as a source of injury increased 83 per cent for women, while dropping 38 per cent for men. Both genders saw substantial decreases in vehicle-related injuries, along with increases in injuries from tools, instruments, and equipment.

Ultimately, the study points to the need for further research to better understand the risks of police work and explore ways to make it safer. Police leaders are also encouraged to consider developing a national police officer injury database to provide the quality of data required for detailed analysis and proactive policy development.
