Canadian stocks bounced back sharply to start the week on a strong note after U.S. president Donald Trump’s claim of potential progress in U.S.-Iran negotiations eased some geopolitical concerns and lifted overall market sentiment. As hopes of easing geopolitical tensions led to a steep intraday drop in oil prices, the S&P/TSX Composite Index jumped by 566 points, or 1.8%, to settle at 31,884 — marking its best single-day performance in over a month.
While nearly all key market sectors ended the session in the green, the TSX rally was mainly driven by solid intraday gains in mining, consumer discretionary, and technology stocks.
Trump stated that a deal with Iran could be reached soon if talks continue to progress. He also indicated that further negotiations are underway, signaling a possible shift toward a diplomatic resolution after weeks of escalating conflict.

Top TSX Composite movers and active stocks
Transcontinental (TSX:TCL.A) rocketed by 44% to $4.82 per share, making it the top-performing TSX stock for the day. While there was no apparent company-specific news driving the surge, the stock experienced a temporary trading halt shortly after the open due to a single-stock circuit breaker triggered by extreme volatility.
Trading in Transcontinental stock was briefly paused by the Canadian Investment Regulatory Organization (CIRO) and resumed minutes later once price stability improved. The sharp move also came amid recent analyst adjustments, including a revised target price reflecting a special cash distribution tied to the company’s packaging business sale.
AbraSilver Resource, Americas Gold and Silver, and Boralex were also among the day’s top gainers on the Toronto Stock Exchange, as they surged by at least 8.6% each.
On the flip side, Vermilion Energy, International Petroleum, Methanex, and Peyto Exploration & Development slipped by at least 3.2% each, making them the session’s worst-performing TSX stocks.
Based on their daily trade volume, New Gold, Canadian Natural Resources, Power Corporation of Canada, TC Energy, and Whitecap Resources were the five most active stocks on the exchange.
