The S&P/TSX Composite Index gained 0.2% to close at 34,139 on Monday, supported by strong gains in the mining sector. Barrick Mining surged 9.1% after beating estimates for first-quarter profit, as higher gold prices helped offset lower production. Other miners also advanced, with Agnico Eagle up 1.9% and Wheaton Precious Metals gaining 3.6%. Meanwhile, oil prices rose on renewed supply concerns after US President Donald Trump rejected Iran’s response to a proposed peace agreement. Energy producers tracked crude prices higher, with Canadian Natural rising 1.4% and Suncor Energy adding 1.7%. Still, elevated energy costs kept stagflation concerns in focus, weighing on financial stocks. Royal Bank of Canada fell 0.6%, while Brookfield lost 1.7%. Elsewhere, Shopify dropped 6.9%.
