Canada’s top-performing publicly traded companies over the past three years reflect a market shaped by a global commodities boom, the country’s infrastructure ambitions and surging demand for artificial intelligence data centres, according to the latest TSX 30 rankings.
The TSX 30 is an annual list compiled by the Toronto Stock Exchange that identifies the 30 best-performing stocks on Canada’s benchmark index, based on dividend-adjusted share price performance over a three-year period. The 2026 edition recorded the strongest results since the ranking began in 2019, with companies on the list posting an average dividend-adjusted share price gain of 785 per cent over three years — nearly double the average from the previous year’s list.
Five technology companies made the cut this year, together adding $85.3 billion in market capitalization over the three-year period. That group included electronics manufacturers Celestica Inc. and Firan Technology Group Corp., space technology firm MDA Space Ltd., energy infrastructure and digital technology company Hut 8 Corp., and satellite operator Telesat Corp.
Celestica topped the overall list for a second consecutive year, posting a dividend-adjusted share price increase of 2,590 per cent over the three-year window. The company, which provides electronic manufacturing and supply chain services to customers in high-tech sectors, counts several large technology firms among its clients and has benefited from strong demand tied to AI-related infrastructure spending.
Mining companies once again made up the largest single segment of the list, accounting for 18 of the 30 spots — a slight increase from the prior year. The mining representation was more varied than in previous rankings, spanning silver, copper and rare earth producers in addition to gold-focused firms.
Robert Peterman, chief commercial officer of the Toronto Stock Exchange, said the results reflect what he described as a commodity super cycle, driven by anticipated shortfalls in the supply of several key commodities over the coming years. He noted that smaller exploration and junior mining companies play a central role in discovering the new mines needed to meet that future demand.
Gold remained a focal point for investors amid ongoing economic and geopolitical uncertainty. The metal surged past US$5,000 an ounce before retreating to trade around US$4,400 — a level still well above historical norms. Peterman said gold and silver were the dominant commodities driving performance on this year’s list.
The energy sector was represented by two companies: international natural gas producer Tenaz Energy Corp. and oil producer Valeura Energy Inc. Energy prices have risen sharply this year following the U.S. military action against Iran, which restricted the flow of crude oil and other commodities through the Strait of Hormuz.
Peterman said the energy sector is undergoing a shift not only in supply levels but in where that supply originates, as countries increasingly weigh energy sourcing as part of national security planning. He said Canada is positioned to benefit from that trend.
Tenaz Energy posted a dividend-adjusted share price gain of 1,463 per cent over the three-year period. Anthony Marino, the company’s president and CEO, said Tenaz aims to perform well regardless of swings in commodity prices, noting the company can hedge in the short term but does not control long-term pricing as a seller of natural gas. He said the company instead focuses on differentiating itself through capital returns and lower operating costs. Marino added that Canada has historically been a supportive environment for energy companies, with investors, regulators and governments recognizing the sector’s importance.
Industrial companies tied to Canada’s infrastructure buildout also appeared on the list, including Hammond Power Solutions Inc. and Bird Construction Inc., which posted a 738 per cent three-year dividend-adjusted share price gain.
Teri McKibbon, CEO of Bird Construction, said the company is involved in a range of major Canadian projects spanning data centres, power, mining, transportation, defence, utilities and industrial development, and that its strategy does not depend on any single sector. He said this diversified exposure to long-term investment programs has supported the company’s performance, and that he expects Canada’s focus on infrastructure development to continue benefiting the sector for years to come, citing some project cycles that extend 20 years.
