Canada’s latest tariff retaliation is putting a fresh spotlight on a more consequential part of the U.S.-Canada trade relationship: critical minerals.
Ottawa announced Tuesday that it will impose tariffs of 15%, 25% and 50% on roughly $20 billion of U.S. goods starting Sept. 8, including steel, aluminum, electronics, appliances and farm equipment. The measures come after Washington imposed a new 50% tariff on about $20 billion of Canadian imports.
The targeted trade is relatively small compared with the broader relationship. U.S. goods exports to Canada totaled $333.6 billion in 2025, according to the U.S. Trade Representative.
But the bigger ETF opportunity may lie outside the tariff list.
Critical Minerals Are the Bigger Risk
Canada exported $28.8 billion of critical minerals to the U.S. in 2025, accounting for about 57% of its total critical-mineral exports, according to Natural Resources Canada.
That makes minerals such as copper, nickel and uranium a potential pressure point if the dispute escalates beyond tariffs. Ontario Premier Doug Ford has already threatened potential restrictions on critical-mineral exports, underscoring the strategic vulnerability of U.S. supply chains.
For investors, that could reinforce the case for ETFs targeting miners and developers outside traditional industrial portfolios.
Copper and Uranium ETFs to Watch
The Sprott Junior Copper Miners ETF (NASDAQ:COPJ) offers a higher-beta way to play a potential acceleration in Western copper supply. The fund has about $174.4 million in assets and charges a 0.75% expense ratio. Its index focuses on small- and mid-cap copper producers, developers and explorers.
Copper is particularly relevant as Washington tries to expand domestic production. Ivanhoe Electric’s Santa Cruz project in Arizona, for example, is designed to produce an average of 72,000 tons of copper cathode annually during its first 15 years. First production is targeted for late 2028, highlighting how long it can take to replace imported supply.
The Global X Uranium ETF (NYSE:URA) offers another strategic-minerals angle. URA has $6.42 billion in assets with Cameco Corp (NYSE:CCJ) as its largest holding at 22.7%. The ETF charges a 0.69% expense ratio.
The key takeaway: a $20 billion tariff package may be manageable, but a prolonged Canada-U.S. dispute that reaches critical minerals could create a much bigger supply-chain shock, and a potentially important catalyst for critical-mineral ETFs.
