Mr Trump’s spokesperson, Karoline Leavitt, bolstered his reputation as an ungracious winner after Mr Carney’s concession. “It’s very simple: Prime Minister Carney and Canada caved to President Trump and the United States of America.”

After President Trump suspended trade talks with Canada over its controversial digital services tax, Ottawa scrapped it to get back to the negotiating table.

But it wasn't just Trump pushing Carney to reconsider the tax. A nonprofit representing CEOs and leaders of some of Canada's biggest businesses, the Business Council of Canada, had warned that Carney defending the tax risked "undermining Canada’s economic relationship with its most important trading partner," Al Jazeera reported.
