Military Abbreviations - Canada, World War I

The National Archives of Canada has a great many records pertaining to individuals military personnel from World War I service. Those records are littered with abbreviations familiar at the time, but now may be obscure. The following abbreviations and their meanings have been extracted from a two-page document that accompanies records acquired from the National Archives. Thanks to AFHS member, Frank Morrow, for bringing this information to our attention.

To search the WW I records held, please consult the Soldiers of the First World War (1914-1918) database.
