Washington Wanted Canada Dependent. It Got the Opposite.

In May, Mark Carney put deeper integration on the table — "Fortress North America," Canadian and American industry fused in specific sectors, the last moment the two countries were pulling the architecture together rather than apart.

Like Mexico, Canada remains open to deeper integration, including options for fortress North America in (certain) sectors. And to be clear, those offers are on the table — Mark Carney

Four months later the offer is gone, and so is much of the machinery it was meant to feed. The forum that has coordinated the two countries' defense since 1940 has been paused. The National Security Strategy that followed put the intent in five words.

A strong Canada that prioritizes hard power over rhetoric benefits us all. — Elbridge A. Colby

Then the vise tightened. The Justice Department cut off antitrust cooperation — the joint work on price-fixing and merger probes in tech, aerospace, and auto parts ^[1]. Tariffs hit 50 percent on $27.6 billion of Canadian goods ^[2]. Trade talks collapsed on August 21 ^[3]. And the pressure was never only economic: the Treasury Secretary was telling Alberta it should "come down into the U.S.," while a half-trillion-dollar line of credit was floated to bankroll the province's exit. The trade collapse was the turning point. Until then Carney had kept offering integration; after it, he stopped offering and started building. He had already named the reason.

great powers have begun using economic integration as weapons, tariffs as leverage, financial infrastructure as coercion, supply chains as vulnerabilities to be exploited — Mark Carney

Canada became the first non-European member of the European Union's Security Action for Europe — a new forum to replace the one Washington paused — and set a date to address the European Parliament ^[4]. A $60 billion defense industrial strategy will replace American suppliers, with submarines from Germany and radar planes from Sweden ^[5]. The F-35 purchase went under review, citing threats to Canadian sovereignty ^[6]. And the armed forces drew up their first plan in over a century for fighting an insurgency against a hypothetical American invasion ^[7]. The squeeze is not total, and it would be wrong to read it as one. Washington dropped its objections to Canada's French-language laws, and British Columbia and Washington State still run a joint interparliamentary group. But the doctrine has an enforcement arm too: Washington has threatened 100-percent tariffs if Canada finalizes a trade deal with China ^[8]. That is the same instruction — discourage collaboration with others — applied to the one partner Canada might turn to next. The result is the opposite of the stated intent. A doctrine written to keep Canada from collaborating with others has driven Canada to collaborate with others faster than at any point in decades. The 80-year architecture is coming down from both sides — one chose hierarchy, the other chose independence, and neither is rebuilding what the other broke.
