The WW2 Canadian Civil Defence Gas Mask Bag is an artifact issued during the Second World War to Canadian civilian defense personnel. Constructed from durable, khaki-colored cotton canvas, this bag was designed to contain and protect the standard-issue civilian gas mask and related accessories. The bag features a flap closure secured by metal snaps or buttons, as well as an adjustable shoulder strap for ease of carrying. Internal compartments and loops are present to organize and stabilize the mask and filter components. It typically bears manufacturer markings, date stamps, and occasionally, the “C.D.” (Civil Defence) lettering. These bags were distributed as part of broader air raid precaution efforts and were an integral aspect of civilian preparedness for chemical warfare scenarios. Today, such items represent a tangible aspect of Canada’s home front efforts during World War II and are of interest for historical study, reenactment, and collecting.
