The Canadian Efficiency Decoration (ED) was a Canadian military award given to officers of the non-permanent active militia, RCAF Auxiliary and Reserve who completed twenty years of meritorious military service. Similar Efficiency Decorations were also awarded by other Commonwealth countries. A bar was issued for an additional 20 years of meritorious service. Approximately 3,700 medals were issued. Time spent in war service counted double towards the 20 year requirement and time spent in the ranks counted as half. This award was superseded by the Canadian Forces Decoration.
