TSX Growth Stocks With High Insider Ownership in May 2026

Canadian investors are weighing the effects of rising yields and strong economic growth after a two-month equity rally, with particular attention on growth stocks backed by significant insider ownership. A Simply Wall St screen identified 47 fast-growing TSX-listed companies with high insider stakes, highlighting names where management’s interests may be closely aligned with shareholders. Among the top 10 on the list are West Red Lake Gold Mines, Sernova Biotherapeutics, ROK Resources, Propel Holdings, Hammond Power Solutions, Electrovaya, Colliers International Group, CEMATRIX, Aritzia and Almonty Industries.

The article focuses on three companies in more detail: Almonty Industries, Aritzia and Hammond Power Solutions. Almonty, which mines, processes and ships tungsten concentrates, has insider ownership of 10.2% and a revenue growth forecast of 40.1% annually. The company reported sharply higher Q1 2026 sales of C$25.4 million, up from C$7.91 million a year earlier, while its net losses narrowed. Insider buying has exceeded selling over the past three months, and the company’s revenue growth is projected to outpace the broader Canadian market. Simply Wall St also said profitability could arrive within three years as Almonty expands its role in global tungsten supply chains.

Aritzia, the women’s apparel and accessories retailer, has 16.1% insider ownership and a forecast earnings growth rate of 21.7% a year over the next three years. The company recently completed a buyback of 1.82 million shares for C$195.3 million, a move that signals confidence in its valuation. Although revenue growth is expected to be slower at 15.1% annually, Aritzia continues to expand its store network with new boutique openings. The company’s latest results showed strong earnings growth, supporting its profile as a high-growth Canadian consumer stock.

Hammond Power Solutions, which designs and manufactures transformers for markets including Canada, the United States, Mexico and India, has the highest insider ownership among the three at 27.4%. Revenue is forecast to rise 20% annually, while earnings are projected to grow 27.05% per year, both ahead of the Canadian market. However, the company has faced some margin pressure, with profit margins falling from 11.2% to 6.8%. Its recent earnings also showed sales of C$264.84 million but lower net income than a year earlier.

Overall, the screen suggests that Canadian growth investors may find opportunities in companies where insiders hold meaningful stakes and business fundamentals remain strong, though each name carries its own operational and valuation risks.
