Before you start

If you are doing genealogy research, gather information such as:

  • name
  • approximate date and place of birth
  • whether the person served in the army, navy or air services

For other historical research, it is helpful to know the name of the regiment, unit or ship.

Places to look

Here is information about our collections.

Military service files

Our records include personnel files of many men and women who served in the war.

Personnel Records of the First World War

This database allow you to search for files in the following Record Groups (RG):

  • Canadian Expeditionary Force (CEF): soldiers, nurses and chaplains (RG150)
  • CEF volunteers who were rejected at Valcartier (RG 9-II-B-13)
  • Non-Permanent Active Militia (RG9 II-B-7)
  • Royal Newfoundland Regiment and Newfoundland Forestry Corps (RG38-A-2-e)
  • Imperial War Service Gratuity Files (RG9 II-F-10) These files relate to Canadians who served with the British forces

Royal Canadian Navy Service Ledger Sheets, 1910 to 1941

This database relates to naval personnel (RG150, Accession 1992-93/170). Only the ledger sheets are included in the database. The database help page explains how to search for other navy service files.

Courts Martial of the First World War

This database relates to CEF service members. It only includes references for the courts martial files that have survived (RG150-8).

Other records relating to service

Our First World War: Personnel records page includes other records with information about individual service members, such as:

  • records relating to Indigenous veterans
  • Air services
  • prisoner of war records
  • hospital records

Death registers, war graves registers and death cards

We hold the following series of records:

War diaries

These are the day-to-day descriptions of CEF units in active service. They contain information about the location of a unit and its military operations. The diaries rarely mention individuals by name, with the exception of some references to officers. The records are digitized.

War Diaries of the First World War explains more about the records and how to access them.

Sailing lists

Our collection of sailing lists (RG9-II-B-3), are arranged by battalion or unit. They usually indicate the ship, date and port when the unit left Canada. The lists include details about each individual on board, such as name, rank, country of birth and former corps.

To see the digitized lists:

  • Go to Collection Search
  • Select Collections and Fonds database.
  • In All these words enter the word nominal plus the battalion number or the unit name (examples 34th, Ammunition Column, Lord Strathacona’s Horse)
  • In Specific terms, select Finding aid and enter 9-24

Ships logs

Ship logs are the official records of Canadian naval vessels, including minesweepers, trawlers and submarines. They contain information about:

  • routine activities at sea and in harbour
  • weather and sea conditions
  • ship movements
  • details of operational exercises and special events such as visits by senior military personnel

There is little or no personal information about individuals in these logs.

Search for ship logs in Collection Search:

  • Click on Advanced search
  • Select Collections and Fonds database
  • In All these words, enter the keyword RG24, the word log and the name of a vessel
    • Examples of keywords:
      • Niobe, Donnacona, TR 17, CD 24

These records are not on microfilm and not digitized.

Military medals, honours, and awards

This collection includes First World War cards, relating mainly to CEF members. Most of the cards contains a typed citation concerning the reason for the honour or award. Many of the citations are the same as what was published in the Canada Gazette or the London Gazette. However, some cards contain unique information.

Not all of the cards explain the reason why the honour or award was granted. For example, after March 1918 commanding officers did not provide specific details relating to the men they recommended for the Military Medal.

Note that these cards include only honours and awards, not service and campaign medals.

The cards can be searched in our Military medals, honours and awards, 1812–1969 database.
