Tariffs and Trade Resource Centre

Discussions on trade policy have spilled over Canada-U.S.-Mexico borders to involve trade partners around the world. With sudden shifts by the new U.S. administration, the continuing threat of new tariffs and trade barriers creates growing uncertainty in the market. These tariffs also provide a strong motivation for businesses to reorient their trade and supply chains to mitigate risk and remain globally competitive.

What would tariffs mean for Canadian exports, sector by sector? What’s the potential impact of retaliatory measures? How would reciprocal tariffs impact Canada-U.S. relations — and your business? How and where can you reposition inbound and outbound trade to other markets?

Keep an eye on this page as BLG’s international trade lawyers bring you the latest on the tariff issue, and how your company can adapt.

The inside track on U.S. tariffs and Canadian trade

From Rambod Behboodi 


June 5, 2025 – No unbound authority: Congress, the U.S. administration, the courts, and the power to tax

Last week, the United States Court of International Trade (CIT) released its highly anticipated ruling on the legality of two sets of tariffs imposed by the President of the United States under the International Emergency Powers Act (IEEPA). The court found that:

The IEEPA does not authorise any of the Worldwide, Retaliatory, or Trafficking Tariff Orders. The Worldwide and Retaliatory Tariff Orders exceed any authority granted to the President by IEEPA to regulate importation by means of tariffs. The Trafficking Tariffs fail because they do not deal with the threats set forth in those orders.

In its summary judgment, the court also found that under the U.S. Constitution, no “narrowly tailored relief” was possible: “if the challenged Tariff Orders are unlawful as to Plaintiffs they are unlawful as to all”. The injunction affected only a subset of tariffs currently in force: for example, those imposed on autos or steel under s. 232 of the Trade Expansion Act 1962 continue in force. The U.S. government appealed the decision, and the US Court of Appeals for the Federal Circuit promptly issued a “temporary” administrative stay of the injunction pending consideration of substantive motions.

How solid is the ruling? From an outsider’s perspective, quite solid on first read. To make sure that I had got the gist of it right, I looked at the critiques of the judgment; they did not disappoint. In fact, the ink was not yet dry on the ruling before John Yoo, of the Torture Memo fame, denounced the ruling as “a flawed decision that improperly intrudes into national security affairs and fails to grapple with the profound constitutional issues at stake.” According to Mr. Yoo, the CIT’s grounds for the decision were “remarkable, indeed unprecedented … [and] range far from the judiciary’s role in foreign affairs.” Indeed, the court, Mr. Yoo asserts, “intrudes into foreign policy in a manner no federal court has ever done before.” Here is the thing: you know the CIT ruling is solid because the critic does not even engage with the case the CIT based its entire decision on: the post-Nixon Yoshida case.

And also because of this – frankly astonishing – sentence: “the Court gestured to broader canons of construction, including the nondelegation and major questions doctrines.” [emphasis added] In a constitutional democracy, the “nondelegation doctrine” – or the Westminster presumption against the validity of “Henry VIII clauses” – is at the very heart of the relationship of the citizenry, the legislature, the Executive, and the power to tax. Courts do not “gesture” to bedrock principles.

So what next?

It is difficult to assess where the Appeals Court – or, indeed, the Supreme Court – ends up. More to the point, the trade policy quiver of the President, as we are all finding out, is full of discretionary and plenary authorities to impose taxes by Executive fiat. As Groucho Marx might have said, “Those are my provisions. If you don’t like them, I got others.” As mentioned, the s. 232 tariffs continue unabated. And not just: in a proclamation issued on June 3, the U.S. President raised the “national security” steel and aluminum tariffs from 25 to 50 per cent (except for exports from the United Kingdom). The Trade Act of 1974, and the Trade Act of 1930, provide additional avenues for the U.S. administration to impose punitive tariffs on trading partners.

In the light of the foregoing, the CIT ruling – and what comes of the various appeals – is only a minor bump in the road. This observed economic and legal chaos is, according to the U.S. Secretary of the Treasury, merely “strategic uncertainty” deployed as a negotiating tactic. Fair enough – though, of course, it remains to be seen what it is that the administration hopes to gain out of the negotiations.

I will leave you with this priceless statement by Senator John Kennedy of Louisiana, a strong supporter of the administration, in response to representations made by the U.S. Secretary of Commerce: “Why are you negotiating trade deals then? … You just said if a country came to you and offered the ultimate reciprocity, no tariff, no trade barriers, in return for doing us the same, you would reject that.”


May 5, 2025 – A new threat to U.S. national security: the imminent demise of Hollywood

The president of the United States announced, in a Sunday afternoon social media post, his intent to declare incentives by its trading partners to their film industries a “national security threat” to the United States.

In his social media posts, the president authorized the Department of the Commerce and the United States Trade Representative to institute a 100% tariff on “any and all Movies coming into our Country that are produced in Foreign Lands.” The White House has since indicated that no definitive decision has been made on the topic, but that “the Administration is exploring all options to deliver on President Trump’s directive to safeguard our country’s national and economic security while Making Hollywood Great Again.

In response to this move, former Alberta premier Jason Kenney noted the support provided to the Canadian film industry and exhorted the Prime Minister to protect the industry against this new threat. Critics of film subsidies underlined, however, the vast resources that governments at all levels pour into the sector and argued that policy makers should take this opportunity to remove what they – the critics – considered wasteful and distorting support for the Canadian film industry.

April 2, 2025 – U.S. trade war escalates: “Liberation Day” promises new barriers to free trade

On April 2, President Trump announced a series of tariffs on imports into the United States:

  • 25 per cent tariffs on foreign-made automobiles and parts;
  • variegated tariffs on a wide range of trading partners;
  • baseline 10 per cent tariff on all other countries; and
  • as reported by news agencies, CUSMA-compliant products will not be subject to the baseline.

News reports also indicate that the exemption for CUSMA-compliant products in “fentanyl” tariffs will continue for the time being.

We underline that the Executive Order has not yet been published. We will provide additional information as and when the EO is signed.
