Canada resets U.S. trade ties: Is Mark Carney’s tariff rollback enough to shield key industries?

Why has Canada removed tariffs on U.S. goods and what does this mean for CUSMA stability?

Canada has taken a decisive step to reset its trade relationship with the United States by removing retaliatory tariffs on goods specifically covered under the Canada–United States–Mexico Agreement (CUSMA). Prime Minister Mark Carney announced the decision on August 22, 2025, confirming that Ottawa will align with Washington’s tariff rollback beginning September 1, 2025.

This policy adjustment comes in the wake of U.S. tariff actions imposed under the International Emergency Economic Powers Act (IEEPA), alongside sweeping sectoral duties applied globally on steel, autos, aluminum, and copper. By restoring tariff-free trade for the vast majority of Canadian goods entering the U.S., Ottawa has effectively secured the lowest effective tariff exposure among America’s trade partners. Over 85 percent of bilateral trade now flows without duties, while the average U.S. tariff rate on Canadian goods stands at just 5.6 percent, well below the nearly 16 percent average levied on other partners.

Carney framed the move as both pragmatic and forward-looking, emphasizing that while this new framework is different from past arrangements, it still positions Canada with the most favorable trade access to the American market.

How have U.S. trade policies shifted and what impact do they have on global trading systems?

Since late 2024, the United States has fundamentally redefined its global trade approach. The new strategy is built on raising tariff revenues, shielding domestic strategic industries, compelling foreign partners to invest inside the U.S., and reshaping non-tariff policies among allies and competitors alike.

Average U.S. tariff rates have risen sharply from just above 2 percent last year to nearly 16 percent today. This marks one of the most abrupt shifts in U.S. trade policy in modern history. Key features include higher baseline tariffs across a wide spectrum of goods, minimal relief on strategic sectors such as steel and autos, and explicit demands for foreign direct investment in American industries.

For Canada, the impact of these shifts has been significant but comparatively muted thanks to CUSMA. While many U.S. partners now face tariff regimes that erode export competitiveness, Canada retains carve-outs that preserve access for most of its trade. Analysts interpret this as evidence of the enduring significance of North American integration, even in an era of protectionism.

Why is Canada retaining tariffs on steel, autos, and aluminum despite broader tariff elimination?

Despite lifting tariffs on CUSMA-covered goods, Ottawa has chosen to retain duties on imports of steel, aluminum, and automobiles. These industries remain central to Canada’s domestic economy, supporting hundreds of thousands of jobs and forming critical nodes in global supply chains.

The steel sector underpins manufacturing and construction, aluminum remains vital to aerospace and energy transition technologies, and the auto industry anchors industrial clusters in Ontario and Quebec. Maintaining tariffs in these areas is intended as a bargaining lever in ongoing negotiations with Washington, which continues to impose high sectoral tariffs on Canadian producers.

Institutional investors have flagged these sectors as high-risk until clarity emerges. Capital investments in steel mills and auto assembly lines are likely to be delayed, given uncertainty over costs and pricing dynamics. However, officials stress that these sectors will be the focal point of intensified bilateral discussions in the coming months.

What role does the upcoming CUSMA review play in shaping Canada’s trade priorities?

CUSMA, signed in 2020, includes a scheduled review process every six years. The next review is set for 2026, but Ottawa has already announced consultations beginning in September 2025 to gauge Canadian priorities in this new trade environment.

The government is expected to frame its approach around sovereignty and competitiveness, seeking to balance Canadian access to the U.S. with strategies that diversify export markets. Officials have suggested that feedback from industry groups, unions, and consumers will directly inform Ottawa’s negotiating position.

For analysts, Canada’s ability to preserve tariff-free flows in 85 percent of goods under CUSMA gives it stronger leverage than other U.S. trade partners heading into review talks. The expectation is that Ottawa will push for clarity in steel, autos, and aluminum while reinforcing CUSMA’s protections across other sectors.

How does institutional sentiment view Canada’s relative trade advantage under the new U.S. regime?

Institutional sentiment toward Canada’s trade position has been broadly positive. Market reactions were swift following Carney’s announcement, with the Canadian dollar appreciating against the U.S. dollar and equities tied to agriculture, energy, and consumer goods recording gains.

Analysts argue that maintaining tariff-free access for the bulk of Canadian exports insulates the economy from inflationary shocks hitting other regions. European and Asian exporters now face higher costs in the U.S. market, while Canadian firms remain relatively shielded. This has already been reflected in foreign institutional investor flows, with Canadian equities showing stronger resilience than peers.

Market strategists describe Canada’s situation as one of “privileged access in a protectionist world,” a status that bolsters investor confidence even amid global uncertainty.

How are tariff-free sectors like agriculture, energy, and consumer goods positioned for growth?

By contrast to the headwinds faced by steel and autos, sectors benefiting from tariff-free flows under CUSMA are positioned to expand. Agriculture remains one of the strongest performers, with Canadian exports of grains, oilseeds, dairy, and meat products continuing to enjoy unhindered access to the U.S. market. Given rising concerns about food security worldwide, this provides Canadian farmers with a stable revenue stream and potential to capture larger market share.

Energy producers also stand to gain. Oil, natural gas, and electricity exports remain deeply integrated into U.S. supply chains, ensuring demand continuity despite turbulence in global commodity markets. With Washington emphasizing domestic energy security, Canadian cross-border energy flows are viewed as strategically essential.

Consumer goods exports—from packaged foods to household staples—are likewise well positioned. Tariff-free status allows Canadian manufacturers to protect margins and maintain competitive pricing for U.S. consumers, ensuring resilience in a market where inflation has already eroded purchasing power.

The Canadian dollar’s stability following Ottawa’s tariff announcement further reflects investor confidence in these sectors. Analysts note that currency markets often act as a proxy for trade strength, and the loonie’s firm footing suggests traders view Canada as a relative safe haven compared to other U.S. trade partners.

How is Ottawa balancing domestic industrial strategy with external trade negotiations?

Beyond tariff policy, the Carney government has pledged to introduce a comprehensive industrial strategy to fortify Canadian resilience. Plans include doubling the pace of homebuilding, developing a new housing industry, and accelerating defense and security supply-chain investments. A Defence Industrial Strategy is also being prepared to ensure Canada can modernize its military capabilities while simultaneously creating jobs and economic opportunities.

Carney emphasized that these initiatives are designed to move Canada “from reliance to resilience.” By catalyzing investment at home and diversifying export markets abroad, Ottawa aims to reduce vulnerabilities that have emerged from decades of trade integration with the U.S.

How might U.S.–Canada security and investment partnerships reshape the relationship?

Carney’s statement placed trade within a broader framework of security partnerships. Canada, as the second-largest foreign investor in the U.S., is deeply embedded in American supply chains, from defense to energy. As Ottawa ramps up investment in defense modernization, new opportunities are emerging for deeper alignment with U.S. military and security strategies.

Analysts see this as a two-track approach: leveraging security integration to build trust with Washington while using economic tools to resolve disputes in steel and autos. The outcome could be a more balanced partnership that expands beyond trade into strategic defense cooperation.

What is the investor outlook for Canadian sectors most exposed to U.S. tariffs?

Investor outlook remains mixed across Canadian industries. Steelmakers, aluminum smelters, and auto assemblers face persistent risks from U.S. tariffs and rising input costs. Institutional sentiment indicates cautious capital deployment in these sectors until bilateral agreements bring clarity.

Conversely, agriculture, energy, and consumer goods enjoy more stability. These industries are expected to remain attractive to investors given their tariff-free status and the role they play in supporting resilient revenue flows.

Analysts predict that as long as Ottawa maintains preferential access to the U.S., Canada will continue to attract foreign direct investment in infrastructure, agri-business, and clean energy. The Canadian dollar’s appreciation underscores market faith in Ottawa’s ability to safeguard competitiveness during an era of volatile global trade.
