Canada and Gas Warfare
Poison gas was used throughout the First World War by almost all armies. The various types of gas, delivered by canisters, projectors, or shell, killed, maimed, denied ground and wore down morale. By 1918, soldiers of all armies encountered gas frequently while serving at the front. Canadian soldiers were among the first to face the death clouds, at the Second Battle of Ypres, and they would have a fraught relationship with gas throughout the war. This article will examine the interaction of Canadian armed forces with poison gas, with a focus on its use in attack, the development of a defence doctrine to protect against it, and its impact on individual Canadians. It will also look at how gassed veterans fared in the war’s aftermath and the creation of chemical weapons in Canada during the Second World War.
