When building a portfolio inside a Tax-Free Savings Account, the goal is usually to find companies that can grow steadily for many years. Because gains and dividends inside a TFSA are generally tax-free, long-term compounders can become extremely powerful wealth-building tools for patient investors.

One Canadian company often highlighted as a “buy and hold forever” candidate is AtkinsRéalis. The firm operates in engineering, infrastructure, and project management, providing services for large-scale projects across sectors such as transportation, energy, nuclear, and environmental solutions.
A key reason investors are paying attention to AtkinsRéalis is the company’s strong backlog of infrastructure and engineering projects. These long-term contracts provide visibility into future revenue, which can make earnings more predictable compared with many cyclical industries. Governments around the world are increasing spending on infrastructure modernization, electrification, and energy transition projects — all areas where AtkinsRéalis has deep expertise.
Another factor supporting the long-term investment case is the company’s improving financial profile. Investors are often encouraged when earnings growth is supported by healthy cash flow rather than just accounting profits. Consistent cash generation allows management to reinvest in new projects, strengthen the balance sheet, and potentially return capital to shareholders over time.
Infrastructure demand also tends to be durable across economic cycles. Major projects such as transportation systems, energy infrastructure, and nuclear facilities often span multiple years or even decades. Because of this, companies involved in designing, managing, and delivering these projects can benefit from long-lasting revenue streams.
For long-term investors using a TFSA, businesses with strong competitive positioning and structural growth opportunities can be particularly appealing. If the company continues expanding its project pipeline and executing efficiently, the potential for steady earnings growth could translate into significant shareholder value over time.

Of course, no stock is completely risk-free. Engineering and infrastructure firms still face challenges such as project delays, cost overruns, or economic slowdowns that could affect contract activity. Valuation also matters — even a strong company can deliver weak returns if purchased at an excessively high price.
