Trump adds 10% tariff on Canada due to a TV ad, even though key economic powers law doesn’t allow its use against ‘informational materials’

Former President Trump announced an additional 10% tariff on Canada, citing a "hostile act" related to an Ontario TV ad criticizing tariffs, further escalating the debate over presidential trade authority. This move, presumed to invoke the International Emergency Economic Powers Act (IEEPA), comes just before the Supreme Court hears arguments on November 5 regarding Trump's ability to use IEEPA for tariffs. Legal experts note that IEEPA explicitly prohibits its application against informational materials, suggesting these proposed tariffs could face significant legal challenges and set a contentious precedent.

Analysis

Former President Trump announced a new 10% tariff on Canada, citing a "hostile act" related to an Ontario TV ad criticizing tariffs, which he deemed a "serious misrepresentation of facts." This proposed duty would be incremental to Canada's existing 35% base tariff rate, though the latter does not apply to USMCA-compliant goods. The move introduces significant uncertainty into North American trade relations, reflecting a moderately negative sentiment.

The new tariff is presumed to invoke the International Emergency Economic Powers Act (IEEPA), a legal basis currently under scrutiny by the Supreme Court, which will hear arguments on November 5 regarding Trump's authority to use IEEPA for tariffs. Legal experts, such as Peter Harrell, highlight that IEEPA explicitly prohibits its use against "information or informational materials," suggesting this specific application could be legally tenuous. This raises questions about the legitimacy of the tariff's justification, as noted by the Tax Foundation's Erica York.

This action underscores the ongoing politicization of trade policy, with the former President explicitly linking the tariff to a perceived attempt to influence the Supreme Court. The administration has previously utilized IEEPA for various tariffs, including those related to the fentanyl trade, but this instance introduces a novel justification tied to informational content. The situation creates regulatory and legislative uncertainty, particularly concerning the scope of presidential authority in trade matters.

Key Decisions for Investors

• Investors should closely monitor the Supreme Court's November 5 hearing on IEEPA's scope, as its ruling will significantly impact future presidential trade authority and the legality of such tariffs.
• Evaluate Canadian trade exposure within portfolios, particularly for sectors reliant on cross-border supply chains, given the potential for increased costs and trade friction.
• Factor in heightened political risk and potential for unpredictable trade policy shifts, especially in the lead-up to future elections, which could introduce volatility.
