Trump's trade war with Canada escalates: Washington imposes 50% tariffs on Ottawa

The trade relationship between the United States and Canada has reached a new low as President Donald Trump implemented a 50% tariff on $20 billion of Canadian imports. This action, which took effect on Saturday, came after last-minute negotiations failed to resolve the ongoing trade dispute. Canadian Prime Minister Mark Carney immediately vowed to match the new U.S. tariffs with his own retaliatory measures.

This latest escalation is part of a broader pattern of trade friction initiated by the Trump administration. Throughout his term, Trump has frequently threatened Canada's economy and sovereignty with new import taxes, even suggesting Canada could become the "51st state" of the U.S. This rhetoric, coupled with waves of tariffs and counter-tariffs, has angered many Canadians and led their government to respond in kind. The resulting uncertainty continues to grow for businesses and consumers on both sides of the border.

The timeline of this trade war has been marked by shifting policies and temporary pauses. Early in Trump's term, threats of 25% tariffs on Canadian imports were made, linked to national emergencies regarding undocumented migration and drug trafficking. These were initially set to take effect in February 2025 but were postponed. A series of more limited tariffs on Canadian goods did go into effect in March. The U.S. also introduced exemptions for automakers and goods compliant with the USMCA trade pact.

However, broader tariffs on steel and aluminum imports, set at 25%, did take effect globally, prompting Canada to impose its own retaliatory tariffs valued at C$29.8 billion ($20.7 billion) on U.S. imports. Trump later announced "reciprocal" tariffs on nearly all U.S. trading partners on April 2, 2025, though he did not reveal additional levies on Canada at that time. These sweeping tariffs have faced legal challenges in the U.S.

If confirmed, the merger between Paramount and Warner Bros. Discovery would create an entertainment giant, combining two major film and series studios, streaming services, and news channels. The state of California and eleven other states have filed a lawsuit against the merger, citing concerns about monopoly risks. Paramount and California officials are scheduled to hold preliminary talks to find a resolution.
