Although Canadian troops arrived in Korea in December 1950, they initially underwent extensive training and did not see action until February 1951.  

The following casualty lists were Department of National Defence press releases for the media.  It should be noted there is a time lapse between the actual dates of casualties and the dates indicated in the press releases.  For example, Casualty List No. 1 is dated 2 March 1951 .  However, Privates Andersen, Brown, Colbourne, MacKay and O'Brien were killed in action on 23 February 1951 .  

Deaths from accidents and other causes were not listed in Official Casualty Lists prior to 2 March 1951 , although they were after that date.  

Categories in the following lists include:           

Killed in Action
Wounded
Died of Wounds
Killed in Accidents
Injured in Action
Accidentally Wounded
Missing in Action
Dangerously Ill
Prisoner of War
Returned From Prisoner of War

Initially, personnel unit affiliation was not included in the lists; it commenced with Casualty List No. 46, although some were identified by corps, such as the Royal Canadian Infantry Corps (RC IC), rather than by battalion and regiment.

A few of the lists are missing numerically.  Hopefully, further research will fill the gaps.
