Canada’s trade surplus widened to its largest in four years as metals and minerals exports ramped up, Statistics Canada reported Tuesday. The country’s trade surplus reached C$4.2 billion, or about $3 billion, in May, up from C$3.4 billion the previous month – the third consecutive trade surplus and the largest since May 2022. YourDailyAnalysis starts with the composition of that growth rather than the headline number: this is not a broad-based export boom, it’s concentrated heavily in metals, minerals and energy, sectors directly tied to global supply disruptions rather than to underlying Canadian manufacturing competitiveness.
Aluminum did the heaviest lifting. Exports rose 0.9% to a record C$77 billion in May and are up 22% over the last four months, with shipments of unwrought aluminum and its alloys the main upside contributor, rising 51% on the month. Those shipments were bound for the Netherlands, Italy and Greece, which Statistics Canada suggested points to Canada diversifying its trade flows. YourDailyAnalysis treats that European destination shift as worth watching closely: a 51% monthly jump concentrated in new markets is a bigger swing than ordinary demand growth would produce, and is more likely tied to buyers actively diversifying away from other aluminum sources amid broader trade and tariff uncertainty.
The energy and Middle East connection is explicit in the data. The value of energy exports is up 70% from a year earlier, and sulfur exports rose sharply in May, which Statistics Canada attributed directly to constrained global supply as sulfur shipments transiting through the Strait of Hormuz slowed once the Middle East conflict began. That’s a concrete example of how the Hormuz disruption covered in other markets coverage this month is also reshaping trade flows in commodities that have nothing directly to do with oil – sulfur is a byproduct of oil and gas processing, and its supply chain runs through the same chokepoint.
The U.S.-specific numbers carry their own political weight. Canada’s trade surplus with the U.S. reached its highest level since January 2025, when companies had rushed to front-run tariffs from President Donald Trump. YourDailyAnalysis reads a surplus with the U.S. returning to those front-running-era highs, more than a year later and without an obvious equivalent tariff-avoidance rush this time, as evidence that Canadian exporters have found durable ways to grow their U.S.-bound trade even as the broader tariff relationship between the two countries remains unsettled.
The volume data adds an important caveat to an otherwise strong-looking report. In volume terms, exports were little changed while imports rose 0.4%, meaning most of May’s export value increase came from higher prices rather than higher shipped quantities, and Statistics Canada itself noted the month will likely end up a net drag on real GDP growth despite the widening surplus. Total imports fell 0.2% overall, driven by declining gold shipments.
Watch whether aluminum’s shift toward European buyers persists into the next data release, which would confirm a genuine diversification trend rather than a one-month anomaly, and watch sulfur and energy export values for how sensitive they remain to developments around the Strait of Hormuz. Your Daily Analysis views the gap between May’s strong nominal trade numbers and its weaker volume figures as the detail likely to matter most for how the Bank of Canada reads this report – a price-driven surplus tied to geopolitical disruption is a different policy signal than one driven by a genuine expansion in Canadian export volumes.
