Introduction
As U.S.-Canada relations face fresh turbulence, Prime Minister Justin Trudeau must navigate complex negotiations with President Donald Trump. With tariffs imposed on Canadian imports, sovereignty concerns raised, and security disputes escalating, an effective strategy is crucial.
One of the most effective frameworks Trudeau can employ is Principled Negotiation, developed by William Ury and Roger Fisher. This method, outlined in Getting to Yes, focuses on achieving mutually beneficial agreements by separating people from the problem, focusing on interests rather than positions, generating multiple options, and insisting on objective criteria. Applying these principles will help Canada secure its interests while preserving a cooperative relationship with the United States.

1. Separate the People from the Problem
President Trump’s negotiation style is known for its confrontational and personal tone. Trudeau must remain composed, avoiding reactive responses while addressing substantive issues. He should acknowledge Trump’s concerns about border security and economic competition without conceding Canada’s autonomy.
Tactically, this requires maintaining a respectful yet firm stance, recognising Trump’s need for public victories while steering the conversation towards practical solutions. Personal diplomacy, leveraging trusted intermediaries, and engaging through multiple channels can help de-escalate tensions.
2. Focus on Interests, Not Positions
Trump’s proposal that Canada join the U.S. as the 51st state is an extreme position, but it stems from economic and security concerns. Rather than rejecting it outright, Trudeau should redirect the discussion toward Canada’s contributions to North American stability.
For instance, Canada could highlight its cooperative role in combating fentanyl trafficking and propose joint enforcement initiatives. Similarly, on trade, Canada could underscore its role in the U.S. supply chain, offering constructive alternatives to blanket tariffs.
Paul Krugman argues that while Trump believes he holds leverage through tariffs, the reality of North American economic integration means that the U.S. would also face significant repercussions. Tariffs would disrupt supply chains, particularly in the automotive sector, increasing costs for U.S. consumers. Recognising these mutual dependencies strengthens Trudeau’s negotiation position.
3. Generate Multiple Options Before Deciding
Rather than being trapped in binary choices, Trudeau’s team should prepare a range of solutions. On tariffs, one option might be a sector-specific trade arrangement ensuring American access to critical minerals in exchange for tariff relief. On border security, Canada could enhance intelligence-sharing agreements to reassure the U.S. of its commitment.
The Guardian reports that Trump has repeatedly delayed imposing tariffs when Canada and Mexico have demonstrated efforts to address border security. This suggests that tariffs serve more as a negotiation tool than an end goal. Offering proactive measures to address U.S. concerns while safeguarding Canadian interests could be a viable strategy.
4. Insist on Objective Criteria
Trump often negotiates based on leverage and perception rather than traditional diplomatic norms. To counter this, Canada must anchor discussions in objective criteria—economic data, international trade laws, and security benchmarks.
For example, rather than debating the legitimacy of tariffs, Canada can present data on job creation in U.S. states dependent on Canadian trade. Similarly, Trudeau can reference existing agreements like USMCA, positioning Canada’s proposals within established frameworks that Trump has already endorsed.
The Economist notes that Trudeau’s current strategy of measured retaliation, balancing national interests with a willingness to engage in dialogue, is prudent. Given the economic risks of escalating trade disputes, Trudeau must continue positioning Canada as a partner in shared prosperity rather than an adversary.

Conclusion
Negotiating with President Trump requires a blend of firmness, adaptability, and strategic foresight. By using Principled Negotiation, Trudeau can avoid reactive posturing, shape discussions around shared interests, and develop creative solutions that preserve Canada’s economic and political standing.
The goal is not merely to resist pressure but to transform conflict into cooperation—securing outcomes that benefit both nations without compromising Canada’s sovereignty. With preparation, discipline, and strategic engagement, Trudeau can steer U.S.-Canada relations toward a more stable and constructive path.
