Trump tariffs pose risk of reprisals: ambassador

Donald Trump’s campaign promise to hike import tariffs could trigger retaliation from other nations including trade partners, Canada’s ambassador to the U.S. warned.

Ambassador Kirsten Hillman said in an interview Friday that Canada thinks the U.s.-mexico-canada Agreement for free trade, negotiated during Trump’s first term, should exclude it from his plan to impose 10 per cent duties on goods from around the world if he’s elected to another term in November. Chinese imports would face a 60 per cent tariff.

“It’s not a one-way street — other countries, if that policy is enacted, will respond,” said Hillman, who helped negotiate the USMCA. “That could potentially raise costs for everybody.”

A second Trump White House should expect trade partners to respond with reciprocal tariffs, as they did for duties on steel and aluminum that Trump imposed in his first term, Hillman said.

Canada, the U.S. and Mexico negotiated the USMCA at Trump’s insistence to replace the North American Free Trade Agreement, which he blamed for the loss of U.S. manufacturing jobs.

Although Trump threatened to end free trade in the region altogether, the nations fashioned a deal that won broad bipartisan support in the U.S. Congress. They’ve since focused on deepening integration, especially in critical industries like semiconductors.

Hillman, who previously worked as a trade lawyer and negotiator, said she doesn’t see the world breaking down into rival trade blocs even though she agreed that returning some supply chains to the region for critical inputs like food and energy makes sense.

Hillman downplayed concerns about a USMCA review scheduled for 2026, calling it an opportunity to improve the deal rather than renegotiate it.

With the U.S. election set for November, Hillman said Canada continues to use its network of consulates to establish relationships nationwide with both Republican and Democratic lawmakers.

“Obviously, that’s deeply important, in order to get as much information as we can from every region to inform ourselves as to what’s happening under both potential outcomes after the next election,” she said.
