The fourth volume in the Canadian State Trials series examines the legal issues surrounding perceived security threats and the repression of dissent from the outset of World War One through the Great Depression. War prompted the development of new government powers and raised questions about citizenship and Canadian identity, while the ensuing interwar years brought serious economic challenges and unprecedented tensions between labour and capital. The chapters in this edited collection, written by leading scholars in numerous fields, examine the treatment of enemy aliens, conscription and courts martial, sedition prosecutions during the war and after the Winnipeg General Strike, and the application of Criminal Code and Immigration Act laws to Communist Party leaders, On to Ottawa Trekkers, and minority groups. These historical events shed light on contemporary dilemmas: What are the limits of dissent in war, emergencies, and economic crisis? What limits should be placed on government responses to real and perceived challenges to its authority?

The third volume in the Canadian State Trials series examines Canadian legal responses to real or perceived threats to the safety and security of the state from 1840 to 1914, a period of extensive challenges associated with fundamental political and socio-economic change. Trials for treason and related political offences, suspensions of habeas corpus, and other public order and security-related measures, supported by new institutions such as secret policing, are studied in essays by leading scholars in the field. The book is divided into four parts: trials and related proceedings arising from the Fenian invasions; attempts to regulate large-scale manifestations of public disorder; trials following the North-West Rebellions of 1870 and 1885, including the Riel trial; and the modernization and enforcement of Canada's national security laws. Building upon the established scholarship of the series, the essays place these legal responses in context, shedding light on the complex and changing relationship between law and politics in Canadian history.

The fifth and final volume of the Canadian State Trials series examines political trials and national security measures during the period of 1939 to 1990. Essays by historians and legal scholars shed light on experiences during the Second World War and its immediate aftermath, including uses of the War Measures Act and the Official Secrets Act with the unfolding of the Cold War and legal responses to the FLQ (including the October Crisis), labour strikes, and Indigenous resistance and standoffs. The volume critically examines the historical and social context of the trials and measures resulting from these events, concluding the first comprehensive series on this important area of Canadian law and politics. The fifth volume's exploration of state responses to real and perceived security threats is particularly timely as Canada faces new challenges to the established order ranging from Indigenous nations demanding a new constitutional framework to protestors challenging discriminatory policing and contesting public health measures.
