The S&P/TSX Composite hovered above the flatline at the 27,340 mark on Tuesday, poised to challenge fresh record highs as a rebound in materials stocks more than offset weakness in technology. Mining giants Agnico Eagle, Wheaton Precious Metals, Barrick Gold and Franco-Nevada each gained about 1% on firmer gold, while copper’s near-all-time high propelled Ivanhoe Mines and First Quantum up nearly 1%. By contrast, Shopify’s more than 1% decline capped the index’s advance, and Canadian National Railway’s shares traded in positive territory as investors awaited its after-hours results. Traders are also parsing tariff developments, Treasury Secretary Bessent’s upcoming talks with Chinese officials have raised hopes of extending the August 12th deadline, and weighing White House signals of potential additional unilateral tariff notices or pre-August 1st trade agreements.
