With Canada's decision to have the United States staff and operate the DEW Line network without Canadian participation, the main phase of negotiations between Ottawa and Washington came to a close. In light of the historically ambiguous relationship that saw a variety of sovereignty conflicts only a decade earlier during World War II, and despite the Department of External Affairs' emphatic calls to "re-Canadianize" the Arctic, by mid-1955 the DEW Line had become an exclusively American-run defense project. This remarkable development became the subject of increasing public scrutiny and growing concerns about the actual extent of Canada's control over the Arctic territories.
This section illustrates how apprehensions about the American presence became more and more articulated in the Canadian government as well as the public sphere through recurrent inquiries and criticism that repeatedly challenged Ottawa's reassurances that Canadian sovereignty was effectively exercised along the DEW Line stations.
