As part of the 100th anniversary commemoration of the First World War, LAC is digitizing the remaining 640,000 Canadian Expeditionary Force members’ personnel service files. To be able to perform this major undertaking, LAC will temporarily close portions of the CEF service files, with 75% of the collection remaining open at all times during the project. At the end of the digitization project, expected in 2015, Canadians will have unprecedented online access to this rich resource and will be able to research high-quality digital copies of the more than 650,000 service files for free. At that point , LAC will no longer take orders for copies. For more information on this initiative, please consult the Fact Sheet: Digitization of Canadian Expeditionary Force Service Files, which will provide updates on the portion of the collection being worked on.
