Two major union leaders call on U.S. President Donald Trump’s top trade official to reconsider a proposed tariff of 50% on Canadian goods, according to reports from Ottawa. Both sources say the request is directed to the senior U.S. trade authority associated with the Trump administration’s trade policy. The unions argue that the proposed tariffs would affect Canadian imports and could have broader implications for trade between the two countries. The reports present the unions’ appeal as a coordinated effort by union leadership rather than a government statement. The articles do not describe specific sectors targeted by the tariff proposal, nor do they provide details of the unions’ evidence or alternative proposals. Both accounts, however, are consistent on the central point: union leaders publicly urge the Trump trade official to revisit or withdraw the proposed 50% tariff on Canadian goods. The reports do not include a response from the U.S. administration or additional steps in the review process.
