Canada is often seen as a peaceful country with a modest military and a small defence industrial base, but its military-industrial complex is deeply embedded in the fabric of the country. Silent Partners reveals its origins and influence. During the Cold War, Canada’s military, industrial, and political partnerships developed in silent ways, behind the scenes and without much public scrutiny. Silent Partners explores this complicated history of leveraging military and defence expenditures to fund domestic industries, bolster employment, and support science and technology. Military and defence spending have affected Canada in myriad ways and in uneven patterns of prosperity and decline. The contributions in this volume explore the environmental impacts of military activities and munitions production, the ethical issues of human experimentation and military testing, and the economic and political implications of procurement and arms exports. Using a vast array of archival sources – some only recently declassified or discovered – Silent Partners is an illuminating examination of Canada’s military-industrial complex from a historical perspective.
