Canadian Prime Minister Mark Carney said Ottawa stands ready to deepen negotiations with Washington after President Donald Trump ordered sweeping tariffs on Canadian imports, setting a 30-day window before the duties take effect.
The new 50% tariffs will target a broad range of goods, from wine and hockey sticks to cement and products previously shielded under the U.S.-Mexico-Canada trade agreement. Energy products, fish, critical minerals, and potash are excluded, as are goods already subject to national security tariffs like steel and aluminum.
Trump invoked Section 338 of the 1930 Trade Act to issue three proclamations authorizing the tariffs, claiming Canada discriminates against American automobiles, alcohol, and cheese. The White House said the action aims to "hold Canada accountable for its continued discrimination against and unreasonable and unequal treatment of U.S. commerce."
Carney framed the tariffs as a violation of the continental trade pact Trump himself renegotiated. "This is the latest in a series of unilateral US trade actions that began with the US imposing a series of tariffs in direct violation of the Canada-United States-Mexico Agreement," he said, adding that Canada has tabled proposals to resolve the dispute and is "ready to intensify those discussions."
The tariff announcement united Canadian political opponents in rare solidarity. Ontario Premier Doug Ford demanded reciprocal retaliation: "If these tariffs proceed, Canada should respond tariff for tariff, dollar for dollar." Canada's Conservative opposition called the move "another unacceptable and unjustified attack on Canadian workers and our businesses," with party members declaring that "Canadians are not a punching bag." The New Democratic Party leader branded the tariffs "the latest economic grenade thrown over the border by an out of control President who has lost touch with reality."
Legal experts have already questioned the constitutional foundation of Trump's approach. Ilya Somin, a George Mason University law professor who challenged previous Trump tariffs, noted that the new duties rest on the same Smoot-Hawley section that "severely exacerbated the Great Depression" nearly a century ago.
The 30-day implementation delay creates space for potential negotiation, though Trump's pattern of tariff threats as a negotiating tactic remains uncertain to resolve the dispute or trigger Canadian concessions.
Author James Rodriguez: "Trump's reliance on Depression-era trade law and Section 338 to bypass normal review processes shows how far executive power has stretched, and Canadian unity on this issue suggests he may have miscalculated the political cost."
