Will the US take control of any part of Canada?
I put only a low single-digit-to-mid-single-digit chance on the United States acquiring any part of Canada before 2029. The current rhetoric is serious enough to keep the tail risk alive, but there is still no credible legal, diplomatic, or military pathway that looks close to producing territorial transfer.
Analysis
The core issue is not whether U.S.-Canada relations are deteriorating; they clearly are. The question is whether that deterioration can plausibly culminate in the United States actually acquiring Canadian territory before 2029, and the evidence for that remains extremely thin. Recent developments are overwhelmingly about tariffs, procurement retaliation, trade leverage, and Canada’s efforts to diversify toward Europe. None of the reporting describes annexation talks, territorial transfer negotiations, or any institutional mechanism that would move an acquisition from rhetoric to reality. Canada’s leadership is also explicitly framing sovereignty as a red line, which makes a voluntary transfer of any part of the country politically implausible.
The main argument for a higher probability is that the Trump administration has shown willingness to use maximalist language and coercive economic pressure, and that can sometimes precede unconventional geopolitical moves. In addition, the sheer scale of the U.S.-Canada relationship means a severe breakdown could create openings for unusual arrangements, especially if a future crisis involved border security, resource access, or a carve-out under some extraordinary bilateral deal. But even then, “acquire any part of Canada” is a much higher bar than tariff escalation or forced market access, and the leap from pressure to sovereignty change is enormous.
Compared with the current market price of 12% for Yes, I think the market is still too optimistic about the chance of territorial acquisition. The situation is newsy and dramatic, which can inflate tail-risk pricing, but the actual pathway to annexation or cession is missing. A more realistic reading is that the relationship may stay hostile, perhaps sharply so, without crossing the line into formal territorial transfer. That makes this a low-probability event, and I would price it well below the market, with only a small but nonzero tail for an extreme diplomatic or constitutional shock.
Arguments
For
- Arguments for Yes: The administration’s rhetoric and willingness to pressure allies increase the tail risk of unconventional moves.
- Arguments for Yes: A severe bilateral crisis could, in theory, produce an extraordinary deal affecting a small piece of territory or jurisdiction.
Against
- Arguments against Yes: There are no reported annexation negotiations, transfer talks, or formal steps toward acquisition.
- Arguments against Yes: Canada is hardening its sovereignty stance and building alternative partnerships rather than moving toward cession.
Key drivers
- There is no visible diplomatic or legal process that would enable a territorial transfer before 2029.
- Canada is actively reinforcing sovereignty and diversifying away from reliance on the United States.
Risk factors
- A future geopolitical or constitutional shock could create an unexpected opening for a limited territorial arrangement.
- Escalating rhetoric and coercive trade policy can sometimes precede more radical policy experiments than markets expect.
Scenarios
Best case
An extreme political or security crisis leads to an unusual bilateral arrangement involving a small territory, border enclave, or jurisdictional transfer that qualifies as U.S. acquisition.
Most likely
Relations stay tense and economically disruptive, with tariffs, retaliation, and alliance realignment, but no part of Canada is acquired by the United States.
Worst case
The U.S. and Canada remain locked in trade conflict, but sovereignty stays intact and the rhetoric never becomes a real territorial process.
