Stewart Prest Warns US Dependence Threatens Canadian Sovereignty
November 2, 2026 | Canada, News, USA, Video interviews
Canada’s dependence on American technology, finance, military equipment and corporate investment has left the country vulnerable to pressure from Washington, political scientist Stewart Prest argues in a new Energi Talks interview.
Prest, author of a Walrus essay titled “Trump Has His Finger on Canada’s Kill Switch”, told host Markham Hislop that the problem goes well beyond President Donald Trump’s trade threats. Canadian systems are so closely integrated with those of the United States that decisions made south of the border can disrupt daily life and limit Ottawa’s options.
“On issue after issue, Canadian systems run through the United States,” Prest said.
The F-35 fighter is one example. Although Prest described the “kill switch” as metaphorical, he said the aircraft’s reliance on American software updates and technical support creates a serious vulnerability if relations deteriorate.
Digital Platforms and Corporate Control
Prest pointed to US sanctions against a Canadian International Criminal Court judge that affected her banking and online services. He also criticized Meta’s decision to block Canadian news on its platforms, arguing that a foreign corporation had restricted an important forum for Canadians to discuss their own affairs.
Hislop raised the layoffs at Stelco and the difficulty of holding American-owned businesses to commitments made in Canada. Prest said contractual rights mean little when enforcement depends on international arrangements or leverage that Ottawa may lack.
The discussion also examined the erosion of Canada’s industrial base. Hislop cited substantial manufacturing job losses in Ontario and Quebec. Prest argued that foreign ownership can shift more than production: head-office positions, research capacity, tax revenue and major investment decisions can migrate abroad as well.
Alberta’s north–south integration provided another case study. Prest said American capital helped develop the province’s resources but also created economic and political relationships that can compete with national priorities.
Building Alternatives, Not Isolation
Prest said Canada should deepen ties with European countries and other democracies to develop alternatives in defence procurement, digital infrastructure and financial services. He welcomed elements of Prime Minister Mark Carney’s effort to diversify international partnerships, while questioning the continued emphasis on attracting large American investors.
He also called for renewed investment in Canadian diplomacy and greater attention to the conditions attached to foreign investment.
The interview explored a potentially larger role for government in financing strategic industries. Prest argued that public capital can support Canadian development without making essential capabilities dependent on foreign owners. Such an approach, he suggested, revives an older understanding of the state’s economic responsibilities.
For Prest, the central challenge is structural rather than personal. Even a change of administration in Washington would not undo decades of integration or erase the possibility of future coercion.
Canada cannot sever its relationship with the United States, he said. But it can create alternatives, preserve more decision-making power at home and become willing to bear the costs of genuine sovereignty.
