• USTR Greer says strong trade ties remain and Canadians want a deal, hinting at pressure to restart negotiations.
  • Talks collapsed in August; no open channels currently exist between Greer and Canada's trade minister.
  • Escalating tariffs and procurement restrictions threaten integrated North American industries.

Fragile Prospects

U.S. Trade Representative Jamieson Greer offered a conciliatory note on Monday, saying there is still a lot of strong trade with Canada and that Canadians want a deal. But the remarks come amid a sharp escalation in tariffs and retaliatory measures, suggesting Washington is applying pressure to restart stalled negotiations rather than signaling an imminent breakthrough.

Trade talks between the two allies reached a near-final stage in August before breaking down. Greer has blamed Canada for making additional requests, while Canadian officials dispute that characterization, pointing to differences over final terms and implementation conditions. The personal relationship between Greer and Canada's Trade Minister Dominic LeBlanc is described as good, but no open channels currently exist between them.

Stalled Talks

The collapse in negotiations has been costly. U.S. tariffs on Canadian steel and aluminum remain at 50%, and autos face Section 232 duties. A tentative arrangement would have reduced Canada's steel and aluminum rate to 25% and cut the auto tariff from 25% to 15%, potentially to 7%, but no agreement was finalized. Disputes over medium- and heavy-duty trucks also proved a major sticking point.

On September 8, the USTR invoked Section 338 of the Tariff Act of 1930 to bar certain Canadian products from the U.S. market and directed the removal of $50 billion in Canadian-origin goods from federal procurement schedules. The measures target motor vehicles, dairy, and alcoholic beverages, though some non-sensitive goods were removed from the scope.

Deep Integration at Risk

The economic stakes are immense. USMCA and its NAFTA predecessor have underpinned roughly $1.6 trillion in regional trade, with production networks that cross the border multiple times before a finished product emerges. Auto parts, metals, and food inputs frequently traverse the frontier, meaning tariffs raise costs for U.S. manufacturers and consumers, not just Canadian exporters.

"What institutional investors like us are really focused on is regulatory stability," Greer said earlier this year, referencing the broader climate for foreign direct investment. "Italy in this regard has been on a very steady growth trajectory." While that comment referred to Italy, the principle applies equally to Canada, where regulatory predictability has been upended by the tariff war.

A further complication: Canada was excluded from recent bilateral U.S.–Mexico negotiating rounds, raising the risk that Ottawa could be presented with a framework shaped without it. Mexican officials have broadly shared U.S. goals on stricter automotive rules of origin, but differ on implementation and seek tariff relief first.

Political Tightrope

Canada's government faces a difficult balancing act. It wants tariff relief and predictable access to its largest export market, but must protect politically sensitive sectors and manufacturing employment. Provinces, firms, and consumers are pressing for retaliation rather than accepting terms viewed as undermining Canadian sovereignty or industrial capacity.

Greer has argued that Canada's retaliatory measures—such as restrictions on U.S. alcohol, procurement, and autos—are unusually escalatory. Canada sees those measures as a response to U.S. tariffs imposed on an ally and USMCA partner.

Path Forward Unclear

The dispute is unfolding during the 2026 USMCA review cycle. The agreement entered into force in 2020 and included a six-year review mechanism; on July 1, President Trump chose not to renew it, starting a 10-year path toward expiration unless all three governments agree to renew or revise it.

In July, Greer said he hoped for separate interim arrangements with Canada and Mexico by year-end, leaving harder USMCA issues for 2027. But with talks frozen and tariffs biting, a limited interim deal focused on tariff relief, sectoral quotas, and transshipment enforcement may be the only plausible near-term path.

Whether Greer's constructive wording signals leverage or genuine openness remains to be seen. If tariff escalation persists, businesses may diversify suppliers, delay investment, and redesign North American production networks—reducing the very integration that has made the Canada–U.S. relationship economically resilient.
