Tariff Sweep Hammers Canada
U.S. tariff actions under the current administration have widened substantially and now cover a huge share of bilateral trade—RBC Economics says the measures now touch more than 70% of U.S. imports from Canada. (rbc.com). Analysts warn that the breadth of coverage matters more than the headline rate because a sweeping set of tariffs acts like a systemic tax that can distort cross‑border investment, a trend tracked by a 'Trump 2.0' tariff tracker.

The United States did not just raise one tariff on Canada. It layered tariffs across steel, aluminum, copper, autos, and other product lines until Royal Bank of Canada estimated the measures were touching more than 70% of United States imports from Canada. (rbc.com) That number is the story. A 10% tariff on one narrow category is a toll booth; tariffs spread across most of a trade relationship start to look like a sales tax on the whole border. (rbc.com, tradecomplianceresourcehub.com) The White House kept widening the list in stages. A July 31, 2025 fact sheet said the administration raised a Canada tariff from 25% to 35%, effective August 1, 2025, under the northern-border emergency order. (whitehouse.gov) Separate tariffs stayed in place on industrial metals. On April 3, 2026, the White House said imported steel, aluminum, and copper were under a strengthened Section 232 program, with copper added in July 2025 at the same 50% rate as steel and aluminum. (whitehouse.gov) The legal plumbing matters because these tariffs did not all come from one law. A Congressional Research Service timeline says the administration used both the International Emergency Economic Powers Act and Section 232 of the Trade Expansion Act, which is why some duties could fall in court while others remain standing. (congress.gov, taxpolicycenter.org) That is exactly what happened in 2026. Multiple trackers say the Supreme Court struck down tariffs imposed under the International Emergency Economic Powers Act in February 2026, but other tariffs, including older Section 232 measures, remained active. (taxpolicycenter.org, icontainers.com) Canada still feels the hit because its exposure is unusually concentrated. Royal Bank of Canada says the rest of the world proved more resilient to the 2025 United States trade shock, but Canada remained heavily dependent on the United States market. (rbc.com) The damage also did not land evenly. Royal Bank of Canada says national output and unemployment held up better than many feared, while losses were concentrated by sector and province, which is what happens when tariffs hit factories, mills, and supply chains rather than the whole economy at once. (rbc.com, fxstreet.com) The investment effect is slower and more dangerous than the customs bill. When a company does not know whether a part will face 0%, 10%, 35%, or 50% next quarter, it delays plant upgrades, reroutes suppliers, or builds the next factory somewhere else. (tradecomplianceresourcehub.com, rbc.com) That is why tariff trackers have become essential reading for manufacturers and customs lawyers. Reed Smith’s April 8, 2026 “Trump 2.0” tracker is basically a running map of which duties are active, which are suspended, and which legal authority they rest on. (tradecomplianceresourcehub.com) So the Canada story is not one giant collapse and it is not one isolated tariff fight. It is a border economy trying to operate while the rules keep changing, with enough tariffs still standing that companies have to price uncertainty into almost every cross-border decision.
