3 Canadian stocks to add to your TFSA in 2026

After ending 2025 with a solid 28% gain, the TSX Composite The benchmark looks set to continue this strong momentum into the new year, as the index is already up nearly 4% in the first month. This early strength is sure to give Tax Free Saving Account (TFSA) growth investors more confidence as they plan ahead for the year and beyond. And a TFSA works best when it’s filled with companies that build for the long term. In this article, I highlight three Canadian stocks you can add to your TFSA in 2026.

MDA Space stock

To get things started, let me start MDA space (TSX:MDA), which has real revenue behind its story, not just hype. The company builds satellite systems, space robotics and geo-intelligence solutions. MDA stock costs about $41 per share, with a market cap of about $5.2 billion. So far in 2026, it has already increased 54%.

So why is the stock moving? In the third quarter of 2025, MDA Space delivered a solid 45% year-over-year (YoY) revenue increase to $409.8 million, driven by higher work volumes in satellite systems, robotics and space operations. Similarly, adjusted EBITDA (earnings before interest, taxes, depreciation, and amortization) rose 49% year-over-year to $82.8 million, while adjusted EBITDA margin remained at 20.2%.

The biggest problem for long-term TFSA investors is the $4.4 billion backlog, which provides strong earnings visibility for years to come. MDA Space also completed its acquisition of SatixFy in early July 2025, which is expected to strengthen its offering of end-to-end digital satellite systems. As demand for broadband and next-generation satellite programs increases, MDA Space aims to convert the backlog into revenue while remaining near margin guidance.

NexGen Energy Shares

Next, let’s shift the focus from MDA to NexGen energy (TSX:NXE), a uranium company that continues to rise in 2026. The company focuses primarily on uranium development in Saskatchewan, anchored by its 100% owned Rook I Project. NXE stock is already up 49% this year and is currently trading at $18.84 per share, with a market cap of about $11.5 billion.

A big driver of this Canadian stock’s strength is a strong flow of project progress. On the exploration side, NexGen recently reported its highest-quality test to date in Patterson Corridor East, including 0.5 meters at 74.8% U3O8, and later said the high-grade subdomain was expanding as it launched a 45,500-meter exploration program in 2026.

The combination of favorable momentum and high-quality exploration results makes NexGen a top Canadian stock for TFSA investors.

Skeena gold and silver stocks

To complete the list, let’s take a look at Skeena Resources (TSX:SKE), a Canadian stock involved in a major redevelopment story in the Golden Triangle. This Vancouver-based company is currently focusing on the rapid progress of its Eskay Creek Gold-Silver Project in British Columbia. After rising 238% in the past year, SKE stock now trades at $47.35 per share with a market cap of nearly $5.7 billion.

This strong share price momentum could mainly be attributed to the milestones the company achieved. The company received major approvals in late January 2026, including an Environmental Assessment Certificate and Federal Impact Assessment approval. These steps are important because they reduce uncertainty and can move the project closer to construction decisions.

Given these developments and its strong long-term growth potential, Skeena can continue to outperform the market over the long term, making it the top stock for TFSA investors in 2026.
