The S&P/TSX Composite Index gained 0.5% on Monday, lifted by strong gains in the mining sector. Barrick Mining surged more than 8% after beating estimates for first-quarter profit as higher gold prices offset lower production. Peers Agnico Eagle (+2.5%) and Wheaton Precious Metals (+3.5%) also advanced. Meanwhile, oil prices rose on renewed supply concerns after US President Donald Trump rejected Iran’s response to a proposed peace agreement. Energy producers traded higher, with Canadian Natural and Suncor Energy both gaining more than 1%. In contrast, elevated energy costs maintained fears of global stagflation, pressuring banking stocks. Royal Bank of Canada fell 0.5%, while TD Bank edged lower. Elsewhere, Doman Building Materials gained more than 4.5% despite reporting first-quarter revenue below expectations.
