Prime Minister Mark Carney set a goal for Canada to double its non-U.S. exports in the next decade, saying American tariffs are causing a chill in investment.

Axar.az, citing AP, reports that Carney, who will release his government’s budget on Nov. 4, said Wednesday many of Canada’s former strengths, based on close ties to America, have become vulnerabilities.

“The jobs of workers in our industries most affected by U.S. tariffs — autos, steel, lumber — are under threat. Our businesses are holding back investments, restrained by the pall of uncertainty that is hanging over all of us,” Carney said.

U.S. President Donald Trump has been threatening Canada’s economy and sovereignty with tariffs, most offensively by claiming Canada could be “the 51st state.”

Carney reiterated in an evening address to Canadians that the decades-long process of an ever-closer economic relationship between the Canadian and U.S. economies is now over.
