TFSA: Top Canadian Stocks for Big Tax-Free Capital Gains

While dividend stocks get a lot of attention these days, the real magic of a TFSA (tax-free savings account) happens when quality growth stocks can grow and multiply. Within the TFSA, capital gains do not need to be reported and are never taxed. Even when you withdraw money from the account, no reporting or taxes are required.

You want your biggest winners to be completely tax-free

That makes it the ideal place for stocks that can deliver significant gains for shareholders. You only get limited contribution room in your TFSA, so you want to choose the best value makers possible.

Small-cap stocks can be an interesting place to look for these types of TFSA gains. A small-cap stock is often in the early stages of its growth trajectory, meaning you still have a long runway to recover.

Below, we look at three top Canadian stocks that could deliver outsized TFSA returns in the coming years.

VitalHub: an emerging software play for a TFSA

One small-cap stock that looks interesting today is VitalHub (TSX:VHI). It has a market capitalization of $569 million today. In August, the market cap was closer to $800 million.

However, shares are down 21% in the past six months. This offers opportunities because the valuation looks attractive again.

VitalHub provides software solutions for public health systems in Canada, the United Kingdom and Australia. The company has grown rapidly. For the first nine months of 2025, revenues are up 62%, and adjusted earnings before interest, taxes, depreciation, and amortization (EBITDA) are up 49%.

VitalHub has over $100 million in cash to invest in further acquisitions, so it appears there is still substantial room for growth. The pullback provides an attractive TFSA entry point.

Firan: a top growth stock in the aerospace sector

Firan technology (TSX:FTG) is another intriguing stock for a TFSA. This $300 million stock is up nearly 500% over the past five years. The combination of a cheap valuation and steady growth made it a great investment at the time.

Firan supplies aerospace parts focused on cockpit components, printed circuit boards and aftermarket hardware/software and sensors. Since the pandemic, demand for new, more efficient aircraft has (literally) skyrocketed.

The major aircraft manufacturers are almost ten years behind. This provides enormous growth for Firan. It has done a good job of making intelligent acquisitions that position it with new customers and new geographies.

To be sure, Firan’s valuation is not as attractive today as it was a year ago. However, it is a much better company than it was five years ago. Likewise, it still trades at a significant discount to other US peers, so there is still room for catching up.

Topicus: A top serial acquirer for a TFSA

With a market cap of $10.6 billion, this latest TFSA stock shouldn’t be considered a small-cap. Yet, strangely enough, it is the largest company listed on the stock exchange TSX Venture Exchange. It is Topicus.com (TSXV:TOI).

Topicus is a serial acquirer of niche software companies across Europe. These are usually mission-critical service providers with very stable revenues. The country has achieved double-digit growth this year and has used its reserve capital very effectively.

The stock is down 27% in the past six months. It is trading at one of the most attractive values ​​since listing in 2021. If you have a longer time horizon, Topicus is an excellent stock to build your wealth tax-free within a TFSA.
