Canada Fights New U.S. Tariffs Over Forced Labour: Ottawa Cites New Legislation and Supply Chain Transparency

The Canadian government has formally urged the Trump administration to exempt Canada from new tariffs being considered under Section 301 of the Trade Act of 1974, arguing that its new legislation combating forced labour in supply chains should shield the country from duties.

In a written submission to the United States Trade Representative's (USTR) office, the Government of Canada said it "remains committed to working closely with the United States to eradicate forced labour from global supply chains."

Ottawa's case was among more than 1,500 written submissions from nations and industry groups ahead of a three-day hearing in Washington this week on President Donald Trump's use of Section 301 to rebuild his global tariff wall around the United States.

This comprehensive analysis examines Canada's argument, the proposed legislation, the broader tariff context, and the implications for North American trade.

Canada's Argument: No Basis for New Tariffs

In its Monday submission, the Canadian government made a clear case for exemption:

"In light of Canada's existing prohibition, complementary supply chain transparency measures, newly introduced standalone forced labour import legislation and continued commitment to Canada-U.S. co-operation, Canada respectfully submits that there is no basis for the imposition of additional Section 301 duties on Canadian goods," the government said.

Canada's submission highlights several key points:

Existing prohibition: Canada already has legislation intended to curb forced labour in supply chains, which requires annual reports to the federal government.
New legislation: The government tabled Bill C-35 last month to boost enforcement, creating a public list of products linked to forced labour in specific regions.
Supply chain transparency: Complementary measures are already in place to increase visibility into supply chains.
Commitment to cooperation: Canada is committed to working with the U.S. on this shared priority.

Bill C-35: Canada's New Forced Labour Enforcement Tool

The centrepiece of Canada's defence is Bill C-35, proposed legislation that would significantly strengthen Canada's ability to combat forced labour in supply chains. Key features include:

Public list of products: The bill would create a public list of products that have been linked to forced labour in specific regions, based on intelligence from embassies and other authorities.
Reverse onus on importers: It would require importers to prove that specific products from listed regions were not made through slavery.
Enhanced enforcement: The legislation would give authorities greater powers to investigate and penalize violations.

This legislation represents a significant step forward in Canada's efforts to combat forced labour, addressing concerns that existing measures were insufficient.

Bill C-35 is currently before Parliament and is expected to pass with broad support. The government has argued that the legislation demonstrates Canada's commitment to combating forced labour and should therefore exempt Canada from U.S. tariffs.

The Section 301 Investigations: Context and Scope

United States Trade Representative Jamieson Greer announced in March that his office was launching trade investigations into 60 countries, including Canada.

Greer said Canada, Mexico, the United Kingdom, and some other countries should be hit with 10 per cent duties because they are not doing enough to enforce bans on forced labour. He also proposed a 12.5 per cent duty on dozens of other countries which have partial or no bans on forced labour in supply chains.

The investigations cover a wide range of products and industries, potentially affecting billions of dollars in trade.

Context: The Evolving Tariff Landscape

The Section 301 investigations did not come as a surprise. It was clear the United States would be looking at new avenues to impose duties after the U.S. Supreme Court struck down Trump's favourite tariff tool, which he used for his "Liberation Day" tariffs and fentanyl-related duties on Canada, Mexico, and China earlier this year.

In response to the top court's ruling, Trump implemented a 10 per cent worldwide tariff using Section 122 of the 1974 Trade Act. Those tariffs were always seen as temporary because they expire after 150 days — at the end of July — unless Congress votes to extend them.

The Section 301 investigations represent a new, potentially more permanent avenue for imposing duties on countries the U.S. believes are not complying with forced labour standards.

CUSMA: The Shield and Its Limits

The Canada-U.S.-Mexico Agreement on trade (CUSMA) has shielded Canada from many of Trump's tariffs. The country is still being slammed by separate duties on industries like steel, aluminum, automobile, and cabinetry.

Many Canadian submissions to the U.S. trade office made the case that CUSMA exemptions should remain in place no matter the outcome of the trade investigation.

Keith Currie, president of the Canadian Federation of Agriculture, wrote that there is "serious concern" the tariffs could expand to goods compliant with the continental trade pact, which would result in "serious and unintended consequences."

"Canada-U.S. agricultural trade is highly integrated and depends on predictable, timely cross-border movement," Currie wrote. "Even modest tariffs could disrupt supply chains, increase input costs, and reduce competitiveness, particularly as many agricultural products cross the border multiple times during processing. These impacts would place additional pressure on farmers and agri-food businesses on both sides of the border."

Canadian Business and Industry Groups Push Back

In separate submissions to the U.S. trade office, Canadian business and industry groups made the case that there are more effective paths to curbing the issue of forced labour than tariffs, particularly in the deeply integrated North American market.

Canadian Chamber of Commerce

Matthew Holmes, Vice President of the Canadian Chamber of Commerce, wrote: "We urge USTR to assess Canada separately under Section 301 … suspend consideration of the proposed 10 per cent tariff while Canada's enforcement reforms are implemented and evaluated, and prioritize targeted bilateral enforcement co-operation over broad country-level measures."

The Chamber's submission emphasized that Canada is already taking meaningful action and should be given time to demonstrate the effectiveness of its new legislation.

Canadian Federation of Agriculture

The CFA expressed concern about the impact of tariffs on the agricultural sector, noting that many agricultural products cross the border multiple times during processing. Tariffs could disrupt supply chains and increase costs for farmers and agri-food businesses on both sides of the border.

The CFA called for CUSMA exemptions to be preserved, arguing that the integrated nature of North American agriculture makes tariffs particularly damaging.

National Foreign Trade Council

The National Foreign Trade Council, an association of U.S. business enterprises, also called for CUSMA exemptions to be extended to any future tariffs, writing that "broad-based tariffs are a blunt, punitive measure that is unlikely to be an effective tool for eliminating forced labour."

The NFTC added: "Moreover, a comprehensive tariff penalizes all goods from a country — including those from companies that have invested heavily to eliminate forced labour from their supply chains."

This argument highlights a key concern: tariffs punish companies and countries that are already taking action, while doing little to address the root causes of forced labour.

What Happens Next: The Road Ahead

The USTR is currently holding hearings to gather input on the Section 301 investigations. The outcome of these hearings will inform the administration's decision on whether to impose tariffs.

Several possible outcomes exist:

Tariffs imposed: The U.S. could impose the proposed 10% or 12.5% tariffs on Canada and other countries.
Exemptions granted: The U.S. could grant exemptions to countries like Canada that have taken action to combat forced labour.
Delayed decision: The U.S. could delay the decision to allow Canada and other countries time to implement reforms.
Alternative measures: The U.S. could pursue other enforcement mechanisms rather than tariffs.

For Canada, the key considerations are:

Legislative timing: Bill C-35 must pass quickly to demonstrate Canada's commitment to enforcement.
Diplomatic efforts: Canada will continue to make its case through diplomatic channels and bilateral discussions.
Business engagement: Canadian business groups will continue to advocate for exemptions.

Implications for North American Trade

The Section 301 investigations have significant implications for North American trade:

Supply Chain Disruption

As the Canadian Federation of Agriculture noted, many North American supply chains are deeply integrated. Tariffs could disrupt cross-border flows, increase costs, and reduce competitiveness. This is particularly true for sectors like automotive, where parts cross the border multiple times during manufacturing.

Uncertainty

The ongoing trade uncertainty is already affecting investment decisions. Businesses are hesitant to make long-term commitments when the trade policy landscape is unstable.

Impact on CUSMA

If the U.S. imposes tariffs on CUSMA-compliant goods, it could undermine the trade pact and create tensions within the North American trading bloc. This could lead to retaliatory measures from Canada and Mexico.

Global Trade Relations

The Section 301 investigations are part of a broader pattern of U.S. trade activism. If the U.S. imposes tariffs on Canada and other allies, it could further strain global trade relations and undermine the rules-based trading system.

Key Takeaways

Canada argues that its new forced labour legislation (Bill C-35) and existing measures provide no basis for Section 301 tariffs.
Bill C-35 would create a public list of products linked to forced labour and require importers to prove products were not made through slavery.
USTR Jamieson Greer proposed 10% duties on Canada, Mexico, and the UK, and 12.5% on other countries.
CUSMA exemptions have shielded Canada from many tariffs, but business groups are concerned about expanding duties.
Canadian business groups argue that tariffs are a blunt instrument that would disrupt integrated supply chains.
U.S. tariff landscape is evolving, with Section 122 tariffs expiring at the end of July unless Congress acts.

Conclusion

Canada is making a strong case that it should be exempt from new U.S. tariffs on forced labour grounds. The government argues that its existing prohibition, complementary transparency measures, and new legislation (Bill C-35) demonstrate Canada's commitment to eradicating forced labour from supply chains.

Canadian business and industry groups are supporting the government's position, arguing that tariffs would disrupt deeply integrated North American supply chains and penalize companies that have invested in eliminating forced labour.

The outcome of the Section 301 investigations remains uncertain. Much will depend on the U.S. administration's willingness to recognize Canada's efforts and the speed with which Bill C-35 is passed into law.

For businesses on both sides of the border, the uncertainty is unwelcome. However, the Canadian government's proactive approach, combined with its strong arguments, provides a solid foundation for seeking exemptions.

Ultimately, this is a test of the strength of the Canada-U.S. trade relationship and the effectiveness of North American trade mechanisms. If exemptions are granted, it will demonstrate the value of cooperation and compliance. If tariffs are imposed, it could signal a new era of trade friction between the two allies.
