Book excerpt: "Compared to the idea that Canada was a nation forged in victory on Vimy Ridge, the reality of dissent and repression at home strikes a sour note. Through censorship, conscription, and internment, the government of Canada worked more ruthlessly than either Great Britain or the United States to suppress opposition to the war effort during the First World War. Polarity, Patriotism, and Dissent in Great War Canada, 1914-1919 examines the basis for those repressive policies. Brock Millman, an expert on wartime dissent in both the United Kingdom and Canada, argues that Canadian policy was driven first and foremost by a fear that opposition to the war amongst French Canadians and immigrant communities would provoke social tensions--and possibly even a vigilante backlash from the war's most fervent supporters in British Canada. Highlighting the class and ethnic divisions which characterized public support for the war, Polarity, Patriotism, and Dissent in Great War Canada, 1914-1919 offers a broad and much-needed reexamination of Canadian government policy on the home front."--
