In a move that blurs the line between economic partnership and political pressure, the U.S. government has quietly taken equity stakes in two Vancouver-based mining companies — Lithium Americas Corp. and Trilogy Metals Inc. — just days before Prime Minister Mark Carney’s visit to Washington.
The decision, presented as a strategy to secure critical mineral supply chains, has stirred unease in Ottawa. Beneath the surface lies a larger geopolitical play: U.S. President Donald Trump’s renewed push for a “North American merger,” a rhetoric that increasingly tests the limits of Canada’s sovereignty.
According to filings, Washington has taken a 5% equity stake in Lithium Americas, along with a 5% ownership position in its Nevada-based Thacker Pass lithium mine. It also acquired a 10% stake in Trilogy Metals, securing the right to expand its ownership at a discount — and, crucially, the right to nominate a board member. Trilogy’s core asset, the Upper Kobuk Mineral Projects in Alaska, hosts major copper, zinc, and gold deposits.
While U.S. officials describe the move as a step toward energy security, critics view it as a calculated show of force. For Canada, the optics are awkward: the same government that forced Chinese firms to divest from Canadian critical-mineral assets must now weigh whether Washington’s actions could also pose a national-security risk.
“The likelihood of Ottawa intervening is low,” noted Sandy Walker, a partner at Dentons Canada LLP specializing in foreign investment review. “But this does highlight how intertwined national security and economic policy have become.”
Under the Investment Canada Act, Ottawa has the authority to review foreign state-owned investments — even minority ones — on national-security grounds. However, outright blocking a U.S. government transaction could escalate already tense trade relations amid ongoing disputes and Trump’s open calls for deeper integration.
Industry Minister Mélanie Joly has the legal discretion to determine “control in fact,” should evidence suggest undue influence. For now, her department is tight-lipped. “Reviews of foreign investments in critical minerals will be conducted in the best interests of Canadians,” a spokesperson stated.
The broader concern is strategic drift. Washington’s new holdings give it a foothold not only in key North American mineral assets but also in the decision-making of companies vital to Canada’s mining ecosystem. If political pressure mounts to relocate corporate headquarters or redirect production south of the border, Ottawa could face another wave of corporate migration — a blow to its already strained productivity and competitiveness.
Carney’s government, already balancing a fragile economic recovery with mounting trade uncertainty, may find itself cornered between diplomacy and defense of economic sovereignty.
The Takeaway:
What looks like a simple investment play is, in truth, a quiet power move. As the U.S. tightens its grip on critical-mineral supply chains, Canada faces a hard question: can it maintain economic autonomy when its closest ally becomes its most assertive shareholder?
