Canada will impose retaliatory tariffs on about $20 billion of annual U.S. imports from Sept. 8, matching the latest U.S. duties dollar-for-dollar while unveiling a C$7.5 billion support package for businesses and workers affected by the escalating trade dispute.
The counter-tariffs will range from 15% to 50% and cover roughly 700 products imported from the United States, the Canadian government said Tuesday.
The measures come after U.S. President Donald Trump imposed new 50% tariffs on about $20 billion of Canadian imports on Saturday, following the collapse of trade talks between the two countries.

The latest exchange marks a significant deterioration in relations between two longtime economic allies and deepens uncertainty for companies operating across the world’s largest bilateral trading relationship.
“Our dollar-for-dollar, rate for rate counter-tariffs as well as a multi-billion dollar support package will protect workers, farmers, families, and businesses,” Canadian Finance Minister François-Philippe Champagne said.
Canada’s tariff schedule targets products according to their sensitivity to Canadian industries and the potential economic impact of the U.S. measures.
Steel, aluminum, furniture and clothing will face 50% tariffs, while cheese, appliances and some seafood will be subject to 25% duties. Electronics and tools will face 15% tariffs, a Canadian government official told reporters.
The measures will also cover prepared foods, perfumes and toiletries, plastics, lumber, wood pulp and paper, carpets and other clothing products. Industrial goods included in the tariff list range from iron and steel and aluminum to hand tools, machinery, electrical equipment, rail engines, motorcycles, furniture and gaming equipment, according to government documents.
Canada calculated its retaliatory tariffs using 2024 trade data. The targeted products represent nearly 4.5% of Canada’s imports from the United States. The U.S. measures, by comparison, affect roughly 5% of Canada’s exports to the United States. While relatively narrow in terms of overall trade, the tariffs could have disproportionate consequences for industries already under pressure.
Wood products are one area of concern, with Canadian kitchen cabinet manufacturers among the businesses potentially exposed to higher U.S. trade barriers.
The concentrated nature of the tariffs means the economic impact could extend well beyond the headline value of $20 billion. Companies facing higher duties may have to absorb some of the additional cost, raise prices, reduce production or reconsider investment and hiring.
Canada is seeking to cushion those effects through a C$7.5 billion package announced alongside the tariffs. The programme includes assistance for small and medium-sized businesses, financing intended to ease corporate cash-flow pressures and support for workers whose employment is threatened by the new trade barriers.
The Business Development Bank of Canada, the federal government’s business lender, will provide part of the financing. Affected companies will be able to access interest-free loans ranging from C$2.5 million to C$5 million.
Industry Minister Melanie Joly said companies would not have to begin repayments for 36 months, effectively taking the repayment period through the end of Trump’s current term. The assistance is intended to give businesses time to adjust their supply chains, find alternative markets and manage the financial shock from the tariffs.
Canada is also using the measures as a political tool.
Joly said the government had deliberately selected some products and industries in ways that could increase pressure on U.S. states ahead of the Nov. 3 midterm elections.
“We’re also targeting products that will target states in the U.S. and so we’re being wise and strategic to put political pressure,” she said.
The strategy represents a shift from simply responding to U.S. tariffs toward attempting to create political costs for American lawmakers and businesses in regions exposed to Canadian demand.
“We need to make sure that the competitors don’t have access to the Canadian market in a better way than their own… products,” Joly said.
The escalation comes after a confrontational series of trade measures between Washington and Ottawa.
Trump’s latest tariffs are relatively limited in terms of the share of total Canadian exports they affect, but their sector-specific impact could be significant. Canada’s dependence on the U.S. market means that even targeted restrictions can disrupt manufacturers and suppliers that have built their businesses around cross-border trade.
The Canadian response introduces a second layer of costs for U.S. exporters.
American companies selling the targeted goods into Canada will now face higher duties, potentially raising prices for Canadian consumers and businesses or forcing U.S. exporters to absorb some of the additional cost to preserve market share.
That creates the possibility of a broader economic spillover if the dispute continues.
The tariff exchange also threatens to complicate supply chains that have developed over decades of relatively open trade between the two economies. Many products cross the U.S.-Canada border multiple times before reaching consumers, meaning tariffs imposed at one stage can raise costs throughout the production chain.
The political rhetoric surrounding the dispute has also intensified.
Trump on Tuesday threatened to rename Lake Ontario, which borders both countries, “Lake America,” adding another provocative element to an already strained relationship.
The immediate priority for Canada is limiting the damage to industries exposed to U.S. tariffs while demonstrating that Washington cannot impose duties without facing a corresponding economic cost. For the United States, the latest measures risk increasing costs for exporters seeking access to the Canadian market while putting additional pressure on companies that rely on cross-border demand.
The larger economic concern is whether the new tariffs remain a temporary negotiating tactic or develop into a prolonged trade confrontation. If the measures remain in place, analysts say companies on both sides may begin making longer-term changes to sourcing, production and investment decisions. That could raise costs and reduce some of the efficiencies created by decades of integrated North American supply chains.
The C$7.5 billion Canadian support package may soften the immediate blow, but it does not remove the underlying uncertainty. The government’s interest-free loans provide companies with additional liquidity, while the delayed repayment schedule gives affected businesses time to adjust.
