The S&P/TSX Composite rose around 0.3% to above the 30,700 mark for the first time on Thursday, supported by strong gains in tech and a continued rally among major mining equities as investors monitored escalating trade tensions between the US and China. Celestica was the top performer, adding nearly 5% on strong demand for AI infrastructure after Goldman Sachs initiated coverage with a Buy rating and a $340 target citing the company’s ability to scale for hyperscale data centers. Shopify added over 3%, benefiting from upgraded analyst targets and renewed optimism around merchant growth and AI-enhanced tools. Agnico Eagle, Barrick Mining, and Franco-Nevada outperformed, adding between about 1% and 2.5% as gold prices continued to test new highs. Meanwhile, US officials on Wednesday criticized China’s tighter rare-earth export controls and warned of potential countermeasures, a development that kept risk-aware traders cautious.
