Canadian Pacific Kansas City reported a big profit boost in its latest quarter despite US tariff disruption and fears over fallout from a potential merger of rivals down the line. The railway saw net income for the quarter ended Sept. 30 rise 10% year-over-year to $917 million. Revenues increased three per cent to $3.66 billion on the back of higher shipping volumes. Grain, potash and container volumes rose markedly year-over-year while forest products — struggling under a sectoral tariff imposed by US President Trump — and energy, chemicals and plastics sagged. …Cross-border steel shipments also dropped due to 50% US tariffs on imports of the metal, though CPKC helped make up the decline with domestic traffic and direct Canada-to-Mexico trade, said chief marketing officer John Brooks. A new item of concern crossed the CEO’s desk over the summer. Union Pacific announced in July it wants to buy Norfolk Southern, and potentially trigger a final wave of rail mergers.
