Canada-U.S. tariffs are becoming an entrenched feature of the bilateral relationship after the latest trade discussions produced no breakthrough and Washington signalled that it is not in a hurry to reach a new agreement.
U.S. Trade Representative Jamieson Greer said on Thursday, October 1, that the two countries still face several outstanding issues that are “quite difficult to resolve.”
His remarks followed a meeting of G20 trade ministers in Milwaukee and offered little indication that suspended negotiations are close to restarting, according to the U.S. Trade Representative.

Canada Us Tariffs: Why the Canada-U.S. tariff dispute remains stuck
The current impasse follows the collapse of intensive negotiations in August.
Prime Minister Mark Carney said on August 21 that Canada was suspending talks after last-minute U.S. terms were deemed unfair and economically damaging, according to his statement.
Carney said the United States was preparing to impose a 50 per cent tariff on approximately $28 billion of Canadian goods, while Canada would respond on a dollar-for-dollar basis.
The federal government later described the affected Canadian exports as worth about $27.6 billion.
The dispute is tied to disagreements over dairy access, alcoholic beverages, motor vehicles, steel, aluminum and other market-access issues.
Washington has argued that Canadian policies disadvantage U.S. exporters, while Ottawa has rejected demands it says would compromise Canadian economic interests, sovereignty and domestic protections.
Greer has also said the Trump administration is comfortable with the current position and does not consider a Canada deal urgent, as new U.S. bans and tariffs on Canadian goods have widened pressure.
That stance reduces the immediate incentive for Washington to make concessions, even as Canadian exporters face continuing uncertainty.
New U.S. restrictions have widened the pressure
The trade dispute moved beyond ordinary tariffs in September, when the United States announced restrictions affecting selected Canadian products.
U.S. measures have targeted products connected to the dispute over Canadian dairy policies, including certain dairy goods, alcoholic beverages and motorcycles.
The White House said the restrictions were intended to respond to what it described as discriminatory treatment of U.S. commerce, according to its action on selected Canadian imports.
Those actions have raised the stakes for Canadian producers and distributors that depend on access to the American market.
They also make a quick return to the pre-dispute trading relationship less likely because companies must now plan around changing duties, exclusions and import rules.
Canada’s tariff response
Canada introduced matching counter-tariffs on selected U.S. products effective September 8, 2026.
The federal list includes goods from sectors such as steel and aluminum, dairy, appliances, agricultural equipment, pulp and paper, plastics and electronics.
The measures apply rates of 15, 25 or 50 per cent depending on the product and are intended to match the corresponding U.S. actions.
Ottawa has also created a remission process for businesses that may be unable to source essential inputs domestically or from non-U.S. suppliers.
Canada’s complete list of products subject to counter-tariffs sets out the covered goods.
Canada has not indicated that it will immediately broaden retaliation across the entire U.S. import market.
Instead, the federal response has focused on targeted countermeasures, financial assistance and efforts to help affected companies diversify their customers and supply chains.
That approach reflects the difficulty of balancing economic pressure against the risk of raising costs for Canadian companies and consumers that rely on U.S. goods, components or raw materials.
What happens next for Canadian businesses
For exporters, the most immediate challenge is uncertainty rather than a single tariff rate.
Companies must determine whether their products fall under U.S. duties, import bans or exemptions, while also assessing how Canadian counter-tariffs affect their American suppliers.
The uncertainty is particularly significant in integrated industries such as automotive manufacturing, agriculture, food processing, metals and transportation.
A product can cross the border several times during production, meaning that tariffs may accumulate before it reaches the final customer.
Ottawa has said it is pursuing new export markets and stronger economic partnerships outside the United States.
The government has also emphasized internal trade, major infrastructure projects and domestic investment as part of a longer-term strategy to reduce Canada’s exposure to a single market.
Canada’s efforts follow earlier pressure to secure a deal, including a new agreement.
CUSMA review adds another deadline
The dispute is unfolding alongside the scheduled joint review of the Canada-United States-Mexico Agreement, or CUSMA.
The agreement remains in force, but the United States did not agree in July to renew it in its current form for the full 16-year period.
Washington has said it wants changes to address trade deficits, market access and other concerns before supporting renewal.
Canada, meanwhile, is seeking stable access to the U.S. market and protection for strategic sectors.
That position follows earlier signals of a swift Canada trade deal.
With tariffs and import restrictions already operating, the review could become the next major venue for negotiations.
However, Greer’s latest comments suggest that the central disagreements remain unresolved and that a quick settlement should not be assumed.
For now, Canadian businesses are operating in a trade relationship that remains formally governed by CUSMA but is increasingly shaped by unilateral tariffs, countermeasures and sector-specific restrictions, echoing earlier warnings that tariffs could signal the end of the U.S. trade era.
