Hot Stocks: Canada’s Top Performers in Q4 2025 – MoneySense

Toronto-based Sigma Lithium Corp., which operates lithium mines in Brazil, led the pack, nearly doubling in value in the three months to Dec. 31, 2025. The performance reflected strong execution — net revenues rose 69% quarter-on-quarter and 36% year-over-year — but also reflected investor interest in lithium, a key component in rechargeable batteries essential to the energy transition.

Vancouver-based Aris Mining came in a distant second, with a return of 61.9%, followed by Toronto-headquartered Discovery Silver Corp. with 58.9%. Aris is a gold miner in Colombia whose shareholders include mining magnates Frank Giustra, Ian Telfer and Neil Woodyer; it consolidated its stake in the Soto Norte property during the quarter and was added to the S&P/TSX Composite in September.

Backed by mining investor Eric Sprott, Discovery Silver acquired the Porcupine Complex near Timmins, Ont., in 2025. from Newmont Corp., which complemented a series of promising assets, including the Cordero project in Mexico. Discovery and Aris were among seven of the top 10 stocks linked to precious metals last quarter, including six miners and the Sprott Physical Silver Trust, an investment vehicle for investors looking for exposure to silver bullion.

By comparison, the 218-member capitalization-weighted S&P/TSX Composite, the standard benchmark for Canadian stocks, rose 5.6% over the period; the total return, including dividends, was 6.25%. Although lower than in the third quarter, these numbers still beat the US S&P 500, which returned 2.35% (2.7% total return) in the fourth quarter.
