Industry Leaders Urge Ottawa to Respond as U.S. Moves Toward 25% Tariffs
The Canadian Steel Producers Association (CSPA) has expressed deep concern over U.S. President Donald Trump’s latest tariff threat, warning of severe economic repercussions for both Canada and the United States. Trump announced on Sunday that he intends to impose 25% tariffs on all steel and aluminum imports, including those from Canada and Mexico, with a formal announcement expected on Monday.
Catherine Cobden, CEO of the CSPA, described the move as a serious risk to jobs and industries on both sides of the border. Reflecting on the 2018 steel tariffs, she warned that such measures had previously caused massive disruptions in supply chains and had negatively impacted manufacturers, businesses, and workers alike.
“We are deeply concerned about the latest tariff threat from the U.S.,” Cobden stated, urging the Canadian government to act swiftly in response. She called on Ottawa to be prepared for retaliatory measures to safeguard the country’s steel sector and broader economy.
Trump’s renewed tariff push comes shortly after he delayed a similar move last week, following discussions with Prime Minister Justin Trudeau and Mexican President Claudia Sheinbaum regarding their respective border security policies. However, the latest threat suggests that diplomatic efforts may not have been enough to shield Canadian exports from another round of protectionist policies.
Cobden emphasized that Canada has aligned its trade policies with the U.S., working to prevent unfair trade practices while ensuring market stability. Despite these efforts, Trump’s tariff plans have revived fears of economic instability and job losses, particularly in steel-producing regions like Ontario.
As Canada braces for the formal tariff announcement, industry experts and government officials are weighing potential countermeasures. In 2018, Canada retaliated with equivalent tariffs on American steel, aluminum, and other goods, forcing the U.S. to eventually roll back its restrictions.
With the North American steel market deeply integrated, industry leaders argue that imposing tariffs on Canada will ultimately harm American industries as well. The automotive, construction, and energy sectors, which rely heavily on Canadian steel, could see rising costs and supply chain disruptions, adding to economic uncertainty.
As the clock ticks toward Trump’s Monday announcement, Canada’s response could determine the future of trade relations between the two nations—a relationship that has long been defined by cooperation but remains vulnerable to political shifts and economic protectionism.
