The Government of Canada, the Department of National Defence and the Canadian Forces are dedicated to honouring those who have made the ultimate sacrifice by ensuring that, when possible, they will be identified and buried in a known grave.
Nearly 28 000 members of Canada’s Army, Air Force, and Navy who died in the First and Second World Wars and the Korean War have no known or maintainable grave. The majority of these service personnel – approximately 19 500 – went missing in France and Belgium during the First World War. Every year, some of the formerly missing are discovered, and the Department of National Defence is responsible for using historical and scientific methods to determine their identity.
Identification is the result of a collection of historical research and biological tests which eventually determine the most likely serviceman.
The first step in identification is to search records, such as military personnel records, burial registrar records, war diaries and maps, and regimental histories to create an historical profile of the unknown person. Purely historical identifications are rare, however, and DND usually seeks biological evidence to support other documents.
Biological anthropologists study the remains to determine the number of persons, their ages and heights, their dental health, their overall health and if possible, clues as to how they may have died. The resulting profile can further reduce the final list of candidates, and genetic testing of the remaining candidates can lead to an identification or reduce the candidate pool further.
Genetic testing of war remains requires that DNA be extracted from bone or teeth and then compared with genetic material donated by the descendents of the candidates.
Unfortunately, the use of DNA, while a method which has made identification more likely, can be limited by the availability of donors and the difficulty of extracting viable DNA from older remains. More recently, National Defence has used stable isotope technology to help differentiate the origins of candidates. By using the regional properties of certain elements to track the mobility of an individual, stable isotope technology can detect the locations in which an individual has been raised (to the age of approximately 21) and the locations in which an individual lived in the final ten to fifteen years of their lives. Such testing allows DND to exclude candidates based on where they were raised or where they lived prior to enlistment.
No doubt new technologies and increased access to historical documents will further enhance the precision and ability to identify Canada’s unknown soldiers, sailors and airmen and airwomen.
