The Canadian Great War Project is intended to promote interest in Canada's participation in World War 1, commonly referred to as the Great War, to research the Canadians who participated in the Great War 1914-1919 or other nationalities who served in the Canadian Expeditionary Force (CEF).
The Canadian Great War Project is a work-in-progress. That is, currently more than 159,681 entries of individual soldiers are available online. New data is being added to the site frequently. The goal is to eventually identify every Canadian man and woman that served in World War One but the project will not be complete for some time yet. If you do not find someone that you are looking for, you might check back again in a few months. Volunteers are encouraged to join in the effort of indexing and adding new records!
