Between 1948 and 1954, the National Film Board of Canada (NFB) produced two films depicting Canadian military personnel training for cold-weather warfare in the subarctic region of Hudson Bay near Churchill, Manitoba. This chapter provides a comparative analysis of each film, examining the social consequences of military-funded research for Indigenous Peoples and newcomers to northern Canada. As historical products of the early Cold War, both films provide a glimpse into southern perceptions of northern Canada and are valuable for understanding the role of science in reinforcing hegemonic attitudes and state goals toward modernization and development in the north.
