The Canadian Forces and civilian participation in the First World War helped to foster a sense of British-Canadian nationhood . The highpoints of Canadian military achievement during the First World War came during the Somme , Vimy , Passchendaele battles and what later became known as " Canada 's Hundred Days " . The reputation Canadian troops earned , along with the success of Canadian flying aces including William George Barker and Billy Bishop , helped to give the nation a new sense of identity . The War Office in 1922 reported approximately 67,000 killed and 173,000 wounded during the war . This excludes civilian deaths in war-time incidents like the Halifax Explosion
