Pacific Command was a formation of the Canadian Army created during the Second World War to strengthen and administer home defence facilities on Canada's Pacific Coast against possible Japanese attack. A second major function was to train reinforcements to be sent to the Canadian divisions in Europe. Pacific Command combined the pre-war Military District No. 11 with Military District No. 13. The command headquarters was initially housed in Esquimalt Fortress near Victoria, but on November 30, 1942 it was moved to the Old Vancouver Hotel in downtown Vancouver. After the United Statesentered the war in December 1941, Canada and the U.S. coordinated their defense of the west coast of North America. Thus Pacific Command operated in close cooperation with Western Defense Command to the south and with Alaska Defense Command to the north. The troops of Pacific Command were concentrated in the three strategic coastal centres:
Victoria-Esquimalt, the capital of British Columbia and the location of Canada's Pacific naval base and headquarters
By the middle of the war a significant proportion of the troops of Pacific Command were conscripts under the National Resources Mobilization Act adopted in June 1940. This act precluded the use of conscripts in overseas operations. However, a plebiscite held in April 1942 released the Canadian government from this restriction. Even after the plebiscite, the government was reluctant to send conscripts into combat outside of North America. The Terrace Mutiny occurred in November 1944 among troops of Pacific Command when it was learned that the government of Prime MinisterWilliam Lyon Mackenzie King had decided to start sending conscripts to Europe to reinforce depleted combat units. In August 1943 troops of Pacific Command participated in Operation Cottage, in the final stages of the Aleutian Islands campaign. However, that campaign ended without a shot being fired at the enemy when it was discovered that the Japanese occupiers of Kiska had already evacuated the island. The only "enemy" the Pacific Command troops inflicted upon physically were American forces, after a Canadian soldier mistakenly shot at American lines, causing a sporadic friendly fire incident between the two forces that left 28 Americans and four Canadians dead, with 50 others injured. Apart from one incident when a Japanese submarine shelled the lighthouse at Estevan Point on June 20, 1942, and the arrival of ineffectual fire balloons launched from Japan between November 1944 and April 1945, the feared military threat from Japan never materialized. The two home defence infantry divisions attached to Pacific Command were thus broken up and their personnel were redistributed to other formations. General Order Number 21/1946, dated 28th January 1946, effective 23rd January, 1946 authorized five Commands, among which was the new Western Command, which appears to have absorbed the area of the former Pacific Command.
