Tips for writing an effective inquiry
If you want to submit an online inquiry, please use the Ask Us a Question Form.
If you are interested in genealogical research and/or the files of military personnel (before and during the First World War, 1914-1918), please use the Genealogy Inquiry Form.
Any inquiry regarding the files of military personnel from 1918 until today (including the files of persons who served during the Second World War) must be signed and sent by mail or fax. The Genealogy and Family History page entitled Canadian Forces after 1918 explains the proper procedures for submitting this type of inquiry.
