Canadian Prime Minister Mark Carney warned that U.S. tariffs could slow the American economy and push it toward a recession [1, 2].

The warning comes as trade relations between the two neighbors deteriorate, threatening the stability of North American supply chains and the livelihoods of workers in both nations.

Carney said that the trade measures would hurt American families and workers [1, 2]. He said that Canada would fight back against the tariffs to protect Canadian workers and diversify its economic partnerships [1, 2].

This escalation follows the collapse of U.S.–Canada trade talks earlier this month [2, 3]. As a result, new U.S. tariffs on certain Canadian exports have reached 50 percent [3].

In response to these measures, Carney said retaliatory tariffs will start on Sept. 8 [3].

While Carney warned of a potential recession in the U.S., he also addressed the current state of his own country's finances. He said that Canada’s economy is currently in a technical recession [4]. However, Carney said the economy is going through a "settling-in" period [4].

The Prime Minister's remarks have gained significant attention online this week, though reports differ on whether the comments are from a recent address or a previous speech resurfacing [1, 2].

Carney said the primary goal of Canada's response is to alert the United States that the current tariff policy could damage the U.S. economy while justifying Canada's defensive trade posture [1, 5].

"We will protect Canadian workers and diversify our economic partnerships."

The collapse of trade talks and the imposition of 50 percent tariffs signal a shift from diplomatic negotiation to economic warfare between the U.S. and Canada. By highlighting the risk of a U.S. recession, Carney is attempting to frame the tariffs as self-defeating for the American economy, while simultaneously preparing the Canadian public for the volatility of a technical recession and the necessity of finding new global trade partners.
