Should companies be allowed to void long-term contracts due to unexpected changes in market conditions?
Algoma Steel filed a lawsuit in Ontario Superior Court on September 29, 2025, to declare its iron ore pellet contract with US Steel void. The legal dispute follows Algoma Steel's notification to cancel the supply agreement established in May 2020.
Why it matters
The dispute centers on conflicting legal jurisdictions and claims of market interference caused by US tariffs. While Algoma Steel challenges the contract validity in Canada, US Steel seeks to enforce the agreement under Pennsylvania law through arbitration.
US Steel is seeking to recover more than $22 million in damages from the alleged breach of contract. The iron ore pellet supply agreement between the two firms was originally signed in May 2020.
The players
Algoma Steel
This steel producer operates out of Canada and is challenging its existing supply obligations.
US Steel
This major American steel manufacturer is seeking financial damages for an alleged breach of contract.
The details
Algoma Steel claims that US tariffs on its products hampered the market for iron ore pellets, justifying the cancellation of the agreement. Conversely, US Steel maintains that the contract is governed by Pennsylvania law and is currently pursuing a separate lawsuit in Pittsburgh.
Timeline
Algoma and US Steel signed the supply contract in May 2020.
Algoma notified US Steel of the contract cancellation on September 29, 2025.
A court ruling regarding the motion to pause the Canadian proceeding is expected on October 26, 2026.
Market Dynamics
The dispute centers on the jurisdictional reach and application of Pennsylvania contract law to international supply agreements. This case highlights the complexity of cross-border supply chain litigation when companies disagree on which legal system governs their trade commitments.
Shareholders and stakeholders should monitor the outcome of the jurisdictional battle, as a ruling to pause or continue proceedings could influence financial liabilities for both firms. The resolution will clarify whether the $22 million claim proceeds through US arbitration or Canadian courts.
The takeaway
Legal disputes over supply contracts often hinge on jurisdictional clauses that dictate where arbitration must occur. Parties in international trade should ensure clear cross-border legal frameworks to mitigate the risk of simultaneous lawsuits in different countries.
What happens next
A court ruling is expected on October 26, 2026, to decide whether the Canadian legal proceeding will be paused.
