Canadians rightly pride themselves on their technological achievements in outer space. Heralded as a pioneer with several “firsts” in space exploration, public perception is that Canada explores the “final frontier” in the name of peace. This is the myth perpetuated by scientists and politicians alike, distorting clear evidence to the contrary. This study aims to rectify this fallacy by demonstrating that Canadian space initiatives were a product of Cold War relations, a need for domestic and international security against the threat of nuclear war. Contextualized within the paradigm of a bipolar world, an ostensibly civilian space program only thinly veiled military objectives. Consulting military, political and scientific sources from the end of the Second World War to contemporary conflicts, what emerges is a complex relationship between civilian and military initiatives. Balancing demands from the United States for hemispheric security against the increasing threat of the Soviet Union whilst maintaining sovereignty over Canadian territory presented immense challenges to government leaders. Coupled with a shrinking defence budget, space research fulfilled specific niche roles in Canadian‐American relations. Deconstructing the objectives of prominent satellite programs, Canada‐U.S. (CANUS) agreements, and concomitant government sponsored defence research into theoretical space programs reveals policy marked by the vestiges of war. Peaceful orientations toward outer space perpetuated in historical literature sets a dangerous precedent. Future conflicts will not always pit technologically advanced societies against underdeveloped armies, and ignoring the military advantages of outer space could prove a fatal mistake in confrontations that will assuredly come.Defence in
