Items from the museum's collection are either displayed in the museum's exhibits, on tour with a travelling exhibitions, loaned out to other institutions, or housed in the museum storage area. From 1982 to 2004, items not on display were stored in off-site facilities; with the Dominion Archives' Trophy Building used as storage from 1967 to 1983, and Vimy House used as storage from 1983 to 2004. During the 20th century, archival materials belonging to the war museum was also held in a warehouse in ByWard Market. In 2004, the museum ceased operating these off-site storage facilities, after it relocated items held there to a new storage space within the new museum building.
