These stocks have posted big gains over the past month and are still excellent buys for 2026

Despite trade-related concerns and macroeconomic uncertainty, some high-quality Canadian stocks posted impressive gains last month. While these stocks have made significant gains in a short period of time, their sustainable business models, strong fundamentals, resilient demand and solid execution position them well to easily outperform the broader stock market in 2026 and beyond.

With this backdrop, here are two TSX stocks that still represent excellent buying opportunities for 2026.

TSX Stocks for 2026 #1: MDA Space

MDA space (TSX:MDA) has started 2026 with impressive momentum. The stock rose more than 44% in January, reflecting renewed investor confidence and its growing share in the fast-growing space economy. Even after this sharp rally, MDA Space remains an attractive investment for 2026 and for the long term.

MDA Space’s technology and solutions enable next-generation space infrastructure. The company provides advanced satellite systems, space robotics and geo-intelligence solutions that support both commercial and government customers. Its technologies support space-based communications networks and Earth observation platforms – areas that are increasingly important for global connectivity and national security.

The broader industrial background is very supportive of this space technology company. The global space economy continues to expand at an accelerating pace, driven by rising demand for satellite broadband, defense-related capabilities and data-rich Earth observation services. Governments are prioritizing space as a strategic domain, while private sector players are investing heavily in satellite constellations and infrastructure to support everything from telecommunications to climate monitoring. MDA Space is well positioned within this ecosystem.

Furthermore, MDA Space’s robust order book provides revenue visibility, while a solid balance sheet provides the flexibility to invest in innovation and scale operations as demand grows. Overall, the industry’s technological leadership, strong tailwinds and financial resilience provide a solid foundation for sustainable growth.

TSX Stocks for 2026 #2: Energy Fuels

Energy fuels (TSX:EFR) shares rose more than 53% last month. Despite the rally, the stock remains a buy for 2026 and a solid investment for long-term investors. It is one of the largest producers of uranium and rare earth metals. It also provides other critical materials. This diversified exposure positions the company to benefit from significant demand tailwinds led by decarbonization, electrification and national energy security.

Additionally, companies like Energy Fuels will benefit as governments prioritize secure domestic supply chains.

Uranium remains an important driving force behind the investment scenario. Demand for domestically produced uranium remains robust, supporting favorable price conditions. Energy Fuels’ low-cost production profile is already translating into rising revenues and healthy cash margins. As the company continues to improve operational efficiencies and control costs, gross margins are expected to further increase, increasing profitability over time.

In addition to uranium, Energy Fuels is steadily expanding its activities in the field of rare earth elements. It is one of the largest fully integrated rare earth producers outside China, with capabilities spanning oxides, metals and alloys. This strategy fits well with the growing demand for rare earth elements in clean energy technologies and advanced manufacturing. Furthermore, the company’s proposed acquisition of Australian Strategic Materials could further accelerate this growth and strengthen its competitive position in global supply chains.

As Energy Fuels ramps up its uranium projects and continues its initiatives in rare earths and heavy minerals, the company appears well positioned to deliver solid returns.
