‘Make your case,’ U.S. Ambassador tells Canada after Trump threatens not to renew CUSMA

U.S. Ambassador to Canada Pete Hoekstra has directly challenged Ottawa to 'make its case' for renewing the Canada-U.S.-Mexico Agreement (CUSMA), just a day after U.S. President Donald Trump publicly threatened not to extend the vital trade pact. Trump declared on June 10 that he is 'not looking to renew' CUSMA, escalating uncertainty three weeks before a crucial July 1 review deadline that could reshape North American trade relations. Hoekstra's comments, delivered at the 2026 U.S.-Canada Summit, framed Trump's provocative remarks not as a rejection, but as an opening for Canada to present its best offer. This high-stakes maneuver by the Trump administration reignites concerns over the future of North America's deeply integrated supply chains, which underpin an estimated $1.93 trillion in annual trilateral trade. CUSMA, enacted on July 1, 2020, includes a unique 'sunset clause' requiring a joint review every six years, with the first due by July 1, 2026, to decide on a 16-year extension. While Canada and Mexico have formally expressed their desire for a full extension, Trump has repeatedly signaled a preference for renegotiation, citing perceived U.S. disadvantages and a desire for more favorable terms on issues ranging from automotive content to steel and aluminum tariffs. His rhetoric suggests a willingness to leverage the upcoming review to push for concessions, potentially forcing CUSMA into a precarious cycle of annual reviews rather than a straightforward renewal. As the July 1 deadline looms, the immediate focus shifts to diplomatic efforts and the specifics of Canada's and Mexico's 'offers.' Canada-U.S. Trade Minister Dominic LeBlanc confirmed Canada has already put 'very specific offers' before the U.S., signaling an active negotiation stance rather than passive acceptance. Should the parties fail to agree on a 16-year extension, the agreement would default to annual reviews, maintaining its force but under a cloud of sustained uncertainty that could deter long-term investment. The coming weeks will test the resilience of North American economic ties against a backdrop of escalating trade tensions and a U.S. administration keen on extracting maximum advantage from its trading partners. Businesses across the continent will be closely watching for any indication of compromise or further escalation.
