A few words about fertilizer have put Canadian agriculture back at the centre of a high-stakes trade negotiation. On November 3, U.S. President Donald Trump said a new agreement with Canada was close and suggested Canadian fertilizer would reach the United States without tariffs. For farmers, that sounds like welcome relief from an unpredictable trade relationship. For Saskatchewan’s potash industry, it is a reminder of how much the American market matters.

But the announcement needs careful reading. Canada and the United States have not signed a new deal, and a significant portion of Canadian potash already enters the American market without the newest tariffs. The real question is whether Trump’s remarks signal meaningful new protection for fertilizer trade or simply another step in negotiations that remain unfinished.

Trump’s Fertilizer Promise Is Still a Proposal

During a November 3 appearance on Fox & Friends, Trump said Washington was close to reaching an agreement with Ottawa and indicated that Canadian fertilizer would be provided to the United States without tariffs as part of that arrangement. In separate remarks reported the same day, he described Canada as a good partner and said a deal could come very soon. The language was optimistic, but it did not specify which fertilizers would be covered, whether existing exemptions would be preserved or expanded, or when any proposed terms would take effect. There was no signed document accompanying the comments. That makes the distinction between a political announcement and an enforceable tariff change especially important for farmers, distributors and Canadian exporters making decisions now.

The comments build on a conversation between Trump and Prime Minister Mark Carney over the weekend. On November 1, Trump said the two governments had the “concept” of a deal that could benefit American farmers, while Carney said their negotiating teams would work in the coming weeks toward a mutually beneficial outcome. Carney also emphasized jobs, household affordability and respect for Canadian languages, culture and sovereignty. Those are broad objectives rather than an agreed schedule of tariff reductions. Trump has also mentioned energy infrastructure and lower barriers for agricultural trade, suggesting the discussions go well beyond a single mineral. For Canadian businesses, the improved tone offers some hope, but it cannot yet be treated as a change to the rules at the border.

Canadian Potash Was Already Exempt From the Newest Tariffs

There is an important qualification behind the suggestion of tariff-free fertilizer: potash, Canada’s best-known fertilizer export, already has significant protection from the latest U.S. trade measures. When Washington announced additional 50 per cent duties on selected Canadian products in July, the White House explicitly excluded potash. The Bank of Canada’s October economic outlook likewise identified potash among the products remaining exempt from those new tariffs. U.S. Geological Survey tariff schedules also listed normal trade relations duties on major potash products as free at the end of 2025. Consequently, Trump’s remarks should not be interpreted as proof that a new agreement has just eliminated a 50 per cent U.S. tariff on Canadian potash. The available official documents do not support that conclusion.

That does not make fertilizer policy simple. Potash supplies potassium, one of the major nutrients crops need, but fertilizer also includes nitrogen and phosphate products that have different classifications, suppliers and trade exposures. Canadian goods qualifying under the Canada-United States-Mexico Agreement can receive preferential treatment when the rules of origin are met and the necessary claim is made. Yet compliance does not remove every type of American tariff, including the Section 338 duties imposed on certain other Canadian goods in 2026. The Bank of Canada estimated in late October that roughly 80 per cent of Canadian merchandise exports to the United States remained tariff-free, even as the average U.S. tariff on Canadian imports reached 7.5 per cent. Any new fertilizer provision needs to be judged against those existing rules.

Why American Farms Depend on Saskatchewan

Canada’s position in the fertilizer trade rests on more than geography. Natural Resources Canada estimated that the country accounted for 32.8 per cent of global potash production in 2024 and exported about 22.9 million tonnes that year. The United States received 53 per cent of those Canadian exports, making it the industry’s most important foreign customer. Statistics Canada subsequently reported Canadian potash production of 24.7 million tonnes in 2025, with sales reaching $9.5 billion. Almost all Canadian potash mining is concentrated in Saskatchewan, where an international trade dispute can be felt far from Ottawa or Washington. A fertilizer order can mean work for miners, rail crews, processing operations and businesses that support entire prairie communities.

American agriculture has an equally practical reason to value the relationship. The U.S. Geological Survey estimated that the United States relied on net imports for 92 per cent of its apparent potash consumption in 2025. Canada supplied 79 per cent of U.S. potash imports over the earlier 2021-to-2024 period. Those figures measure different things, but both underline how difficult it would be to replace Canadian supplies quickly. Potash provides potassium that helps plants grow and cope with stresses, including dry conditions. It can move from Saskatchewan toward American farming regions through established rail networks rather than taking an overseas shipping route. For growers planning nutrient purchases, dependable access to supply can matter as much as a headline promising a better trade relationship.

Rising Fertilizer Costs Give the Comments Political Weight

The attraction of tariff relief is easy to understand when American farm budgets are already under pressure. In its September 2026 forecast, the U.S. Department of Agriculture projected spending on fertilizer, lime and soil conditioners would climb by $5.3 billion, or 15.3 per cent, from 2025 to 2026, reaching approximately $39.6 billion. Total farm production expenses were forecast to rise to $492.8 billion. Those increases cannot all be blamed on Canadian tariffs; fuel prices, global supply conditions and other costs also influence what farmers pay. But they explain why fertilizer availability has become a political issue. When planting plans involve thousands of acres, even relatively small movements in input prices can affect the money left after a harvest.

Agricultural industry groups have warned about precisely that exposure. In March 2025, The Fertilizer Institute and the Agricultural Retailers Association said tariffs on Canadian potash, ammonium sulfate, nitrogen fertilizers and sulfur could raise production costs throughout the U.S. farm supply chain. Consider a hypothetical grain operation covering 1,000 acres: an additional $10 in fertilizer expenses per acre would mean another $10,000 in costs. That is an illustration, not a forecast of savings from Trump’s proposed deal. Even where import duties disappear or remain at zero, retail fertilizer prices depend on transportation, distribution contracts, exchange rates and global commodity markets. Farmers therefore have reason to welcome predictable trade terms without assuming the president’s remarks will immediately lower their next invoice.

Saskatchewan Has Leverage, but Also Faces Competition

The new comments also arrive after a period of uncertainty over where Washington wants to buy its potash. In September, Trump raised the possibility of obtaining cheaper supplies from Belarus, a move that attracted concern in Saskatchewan. He subsequently acknowledged that the United States would continue purchasing Canadian potash while seeking lower prices. The competing supply routes help explain the bargaining. Belarusian material faces a much longer journey through rail links, seaports and ocean shipping before reaching many U.S. farm customers. Saskatchewan producers benefit from proximity and established transportation networks. That advantage is real, but it does not make the industry immune to price pressure or efforts by American buyers to diversify suppliers.

Canadian producers are pursuing alternatives of their own. In September, Saskatchewan announced that potash exporter Canpotex was beginning a $500-million upgrade at Neptune Bulk Terminals in the Vancouver area to improve access to overseas markets. Canpotex markets potash from Nutrien and Mosaic and serves customers in more than 40 countries. Saskatchewan reported potash exports worth about $9 billion in 2025, up 13.5 per cent from the previous year. Better port capacity could strengthen sales to markets outside the United States, though expanding overseas business is not an instant substitute for the large American customer base. For mining communities and exporters, the most valuable outcome may be an agreement that reduces the risk of sudden policy reversals, not merely a promise of zero tariffs.

A Broader Trade Agreement Still Has Major Obstacles

Fertilizer is only one part of a much more difficult negotiation. Canada-U.S. talks broke down in August after Ottawa objected to American demands affecting Canadian sovereignty, language protections and the auto sector. Washington subsequently imposed 50 per cent tariffs on a range of Canadian goods, and Canada retaliated with duties of its own. More recent discussions have raised the possibility of relief for steel and automobiles, but those possibilities have not been translated into a published agreement. The uncertainty extends to the existing continental trade pact: the United States declined to approve a fresh 16-year extension of CUSMA at its July 2026 joint review. That decision did not terminate the agreement, which remains in force while its review process continues.

The next meaningful development would be specific written terms: the fertilizer products covered, the tariff rates being changed or guaranteed, the effective dates and the treatment of other disputed industries. Businesses would also need official implementation guidance before regarding new arrangements as operative. The economic stakes reach beyond potash. Canada’s Parliamentary Budget Officer estimated in October that trade measures introduced since early 2025 could leave real Canadian GDP 1.4 per cent below a pre-tariff baseline after five years if the measures persist. That is a modelled comparison, not a recorded contraction. Trump’s November 3 comments suggest a possible path toward easing tensions. Until both governments confirm binding terms, however, Canadian fertilizer exporters and American farmers are still operating under the rules already in place.
