Some Tax-Free Savings Account (TFSA) investors prioritize capital appreciation over recurring income streams. Instead of dividend stocks, they invest in growth stocks to supercharge their TFSAs. They believe a substantial price surge outweighs the payouts.
The TSX30, an annual ranking of the 30 top-performing TSX stocks, can serve as a guide for growth-focused TFSA investors. For 2025, the average three-year price appreciation of the stocks on the List was 431%. Celestica (TSX: CLS) and Cameco (TSX: CCO) have sustained their momentum. Consider adding both winning stocks to your TFSA this year, along with high-flyer Firan Technology Group (TSX: FTG).

Top growth stock
Celestica ranked second in 2024, then rose to the top in 2025, delivering a massive return of +1,599% over three years. The $46.5 billion technology leader produces hardware for hyperscalers. Its core business areas include data center infrastructure for artificial intelligence (AI), cloud, and hybrid cloud. The company also operates in high-growth markets.
Two operating segments, Connectivity & Cloud Solutions (CCS) and Advanced Technology Solutions (ATS), contribute to revenues. Celestica delivered strong financial performance in 2025, notably a 28% and 53% year-over-year increase in revenue and adjusted net earnings to $12.4 billion and $703.2 million, respectively. The revenue forecast for 2026 is $17 billion.
“We believe the revenue growth trajectory that we anticipate in 2026 will be sustained into 2027,” said Rob Mionis, president and CEO of Celestica. CLS currently trades at $401.74 per share. Market analysts’ 12-month high price target is $460. They recommend a buy rating.
Pure-play nuclear giant
Cameco provides nuclear fuel and nuclear power products, services, and technologies across the fuel cycle. The $75.3 billion Saskatoon-based company and Brookfield Renewable Partners have 49% and 51% ownership stakes in Westinghouse Electric Company, a major nuclear energy company.
Cameco sells itself as a pure-play investment in the growing demand for nuclear energy. The focus is on electrification and decarbonization, as well as addressing the tech sector’s demands. Its ultimate objective is to provide carbon-free and secure baseload power.
In 2025, net earnings climbed 243% year over year to $590 million. Cameco also paid off its US$200 million term loan in the United States during the year. The modest 0.14% dividend is a bonus. Management said the company has advanced its dividend growth plan. At $172.88 per share, CCO’s trailing one-year price return is +212%.
Potential TSX30 winner
Firan, a $522.3 million global aerospace and defence supplier, manufactures high-technology printed circuit boards (PCBs). This small-cap stock continues to crush the market. At $20.75 per share, the year-to-date gain is 79.7%. Given its +544.4% total three-year return, FTG is a potential TSX30 winner in 2026.
Sophisticated printed circuits account for more than 70% of Firan’s revenues, while 75% of total sales come from the U.S. market. In 2025, total adjusted net earnings increased 31% year over year to $13.5 million. Management’s primary goal is to become the dominant player in North America’s PCB industry.

Tax-free fortune
