TSX Composite Index Extends Rally on Mining Strength Amid US-Iran Trade Tensions

The Toronto Stock Exchange (TSX) Composite Index rose by around 0.16% to approximately 36,678 points on Monday morning, August 24, 2026, building on its previous day's gain of 0.7%. The increase was largely driven by strength in mining and banking stocks.

Mining and metals stocks led the advance, with Denison Mines, Ero Copper, Energy Fuels, and G Mining Ventures surging at least 8.6% in early trading. This rally is supported by high gold prices, which have been near record levels in recent sessions, benefiting TSX-listed precious-metals producers.

Canadian Pacific Kansas City shares also rose after resolving a nearly three-month labor dispute, with affected employees set to return to work on Monday morning. The resolution eased operational uncertainty for the railway operator and removed a significant overhang that had weighed on the broader industrials sector in recent months.
