Senate rebukes Trump again: Lawmakers block Canada tariffs in fresh blow to his trade agenda

The U.S. Senate on Wednesday voted for the second time in as many days to overturn former President Donald Trump’s controversial tariff policies — this time targeting his duties on neighboring Canada. The move marked yet another pushback from Congress against the protectionist trade agenda that once defined Trump’s presidency.

The resolution to nullify Trump’s tariffs on Canadian imports passed narrowly, 50–46, as four Republicans — Mitch McConnell of Kentucky, Susan Collins of Maine, Lisa Murkowski of Alaska, and Rand Paul of Kentucky — joined Democrats in support. The same quartet had broken ranks a day earlier to reject Trump’s tariffs on Brazilian goods, signaling growing bipartisan fatigue over the lingering economic consequences of trade wars.

A Repeat Rebellion Against Tariff Tensions

The Senate’s decision wasn’t unprecedented. Lawmakers had already voted earlier in the year to block the same Canada tariffs, but the renewed effort came after Trump abruptly halted trade discussions with Ottawa.

According to sources familiar with the matter, the former president pulled out of talks after Ontario aired a commercial during the baseball playoffs featuring a clip of former President Ronald Reagan criticizing the dangers of tariffs — a message Trump claimed was manipulated. In apparent retaliation, Trump announced plans to raise duties on Canadian exports from 35% to 45%, though the increase has yet to take effect.

Canadian Prime Minister Mark Carney has maintained that his government is ready to resume negotiations once Washington signals willingness to engage. “We were making progress on steel, aluminum, and energy cooperation,” Carney said earlier this week, describing the trade collapse as “unfortunate but reversible.”

Republicans Split as Trade Wars Lose Favor

For senators like Susan Collins, whose home state of Maine shares deep trade ties with Canada, the vote was personal as much as political. “The economies of Maine and Canada are intertwined,” she explained, noting that the tariffs have hurt small manufacturers and strained long-standing cross-border relationships.

McConnell also criticized Trump’s reliance on Reagan-era comparisons to justify his trade strategy. “The economic harms of trade wars are not exceptions in history but the rule,” he said in a statement, adding that no interpretation of Reagan’s remarks supports blanket tariffs against allies.

While some Republicans, including Sen. Thom Tillis of North Carolina, defended the tariffs as “necessary leverage,” others expressed concern that such measures risked alienating close allies while failing to achieve meaningful industrial gains.

The Larger Economic Context

The Senate’s vote reflects a broader reevaluation of U.S. trade policy after years of volatility. Economists warn that tariffs on Canada — one of America’s top trading partners — have inflated costs for key industries like automotive and agriculture, while doing little to protect domestic producers.

“Canada and the United States share one of the world’s most deeply integrated economic relationships,” said Dr. Paul Henderson, a trade analyst at the Brookings Institution. “When tariffs hit Canada, they inevitably hit American workers and consumers too.”

Although the latest Senate vote is largely symbolic — as Republican House leaders have blocked similar measures until at least March — it sends a strong signal that bipartisan appetite for Trump’s aggressive tariff strategy is fading.

Looking Ahead

A third Senate vote, expected Thursday, will address Trump’s global tariff authority, further testing GOP unity on economic nationalism. For now, the message from the Senate is clear: lawmakers on both sides of the aisle are weary of policies that risk trade wars with close allies and threaten U.S. credibility on the global stage.
