Thompson’s nickel mining industry could help shelter the northern Manitoba city from the worst of new U.S. trade measures, but local businesses may still feel the sting. On July 20, 2026, U.S. President Donald Trump announced 50 per cent tariffs on a broad range of Canadian goods set to take effect August 19, rattling communities that depend on cross-border trade.
The tariffs target many products that previously entered the U.S. duty-free under the Canada-United States-Mexico Agreement, including dairy, alcohol, and automotive goods. However, energy, potash, critical minerals such as nickel, and fish are exempt. That exemption directly shields the Thompson Nickel Mine, where a new ownership group is preparing to invest up to $280 million to double production and sustain the roughly 700 staff and 300 contractors who work there.
A new report from the Canadian Federation of Independent Business warns that while small business confidence nationwide ticked up to 58.3 points in July, the renewed trade uncertainty could quickly reverse those gains. Manufacturing sector confidence sits at a more fragile 53.7 points, and CFIB Director of Economics Andreea Bourgeois said optimism among manufacturers remains below historical averages, with many struggling against rising input and shipping costs.
Those pressures could land on Thompson’s local shops, suppliers, and service providers even if the mine itself avoids direct tariff hits. Mining and quarrying together with support activities have historically contributed over 32 per cent of the city’s employment income, meaning any slowdown in investment or uptick in supply chain prices could ripple through the community.
Prime Minister Mark Carney called the U.S. action “the latest in a series of unilateral U.S. trade actions” that violate CUSMA and said Canada has put forward detailed proposals to resolve the dispute and modernise the trade pact. Manitoba has already pulled American products from liquor marts, launched a Buy Local campaign, and set up a tariff hotline while tweaking procurement rules to favour Canadian suppliers.
The Thompson mine’s new consortium of Exiro Minerals, Orion Resource Partners, and the Canada Growth Fund expects to close its deal by the end of 2026, a move local leaders have welcomed as a vote of confidence in the operation’s future despite growing trade turbulence.
