Prime Minister Mark Carney said Ottawa is standing up for Canadian workers and businesses after U.S. President Donald Trump called Canada "nasty" [1].

The exchange occurs as both nations navigate a critical period of trade review. The rhetoric signals potential friction in the ongoing evaluations of the Canada-U.S.-Mexico Agreement, known as CUSMA, which governs billions of dollars in cross-border commerce.

Speaking in Saguenay, Quebec, on Thursday, Aug. 6 [1], Carney said the U.S. president's choice of words was noted. He focused on the economic stability of the domestic workforce rather than the personal nature of the remark.

"The whatever adjective is used, yes. We're standing up for Canadian workers, for Canadian businesses," Carney said [1].

The Prime Minister's comments come amid a broader effort to signal that Canada remains active and vigilant in its review of the CUSMA trade deal. The agreement is a cornerstone of North American economic integration, and any instability in the relationship between the two largest partners could disrupt supply chains.

President Trump's description of the country as "nasty" [1] reflects a recurring pattern of blunt diplomatic communication. However, the Canadian government's response emphasizes a policy of economic defense over diplomatic retaliation.

Carney said he would not specify which sectors of the economy are most at risk but maintained that the government's priority is the protection of Canadian industry during the current trade review process [1].

"We're standing up for Canadian workers, for Canadian businesses."

This interaction highlights the precarious nature of the North American trade relationship as CUSMA undergoes review. By framing his response around the protection of workers and businesses, Carney is attempting to pivot a diplomatic insult into a domestic political strength, signaling to the U.S. that Canada will not be intimidated during trade negotiations.
