Introduction: Why Debt-to-Equity Matters
The debt-to-equity (D/E) ratio is one of the most critical measures of a company’s financial health. It compares total liabilities to shareholder equity, showing how much leverage a firm uses to finance operations. A lower D/E ratio generally signals stability, reduced risk, and greater flexibility in navigating interest rate fluctuations. In Canada’s current environment of elevated borrowing costs, companies with strong balance sheets and low leverage stand out as safer long-term investments.
1. Celestica Inc. (TSX: CLS)
Celestica, a global leader in supply chain solutions and electronics manufacturing, has emerged as one of Canada’s most financially disciplined firms. As of late 2025, the company boasts a debt-to-equity ratio well below 1, supported by a market capitalization of approximately CA$46.9 billion. This conservative capital structure has allowed Celestica to deliver a 197% one-year return, reflecting investor confidence in its ability to scale without overleveraging.
The company’s strong equity base and limited reliance on debt have positioned it to expand across North America and Asia while maintaining resilience against interest rate volatility. For investors seeking growth with financial prudence, Celestica represents a compelling option.
2. AtkinsRéalis Group Inc. (TSX: ATRL)
Formerly known as SNC-Lavalin, AtkinsRéalis has transformed itself into a diversified engineering and project management powerhouse. With a market capitalization of CA$14.5 billion and a debt-to-equity ratio under 1, the company has significantly improved its balance sheet compared to prior years.
AtkinsRéalis has benefited from strong demand in infrastructure and energy projects, particularly in Canada, the U.S., and the Middle East. Its disciplined financial management has translated into a 16.7% annual return, proving that reduced leverage can coexist with steady growth. The company’s ability to generate consistent cash flows while keeping debt manageable makes it a standout in the industrial sector.
3. K92 Mining Inc. (TSX: KNT)
K92 Mining, focused on gold exploration and production in Papua New Guinea, is another Canadian-listed company with a robust financial profile. With a market capitalization of CA$5.6 billion and a debt-to-equity ratio comfortably below 1, K92 has avoided the pitfalls of excessive borrowing common in the mining industry.
The company’s 165% one-year return underscores investor enthusiasm for its growth trajectory, supported by strong production results and rising gold prices. By maintaining a lean balance sheet, K92 Mining ensures that operational expansion is funded primarily through equity and retained earnings, reducing exposure to debt-related risks.
4. Wesdome Gold Mines Ltd. (TSX: WDO)
Wesdome Gold Mines, with a market capitalization of CA$3.5 billion, has consistently demonstrated financial discipline. Its debt-to-equity ratio remains below 1, reflecting a cautious approach to financing exploration and development projects.
The company’s focus on Canadian gold assets has yielded strong operational performance, with steady production growth and rising profitability. Wesdome’s conservative leverage strategy allows it to reinvest earnings into exploration while minimizing interest expenses, making it a reliable choice for investors seeking exposure to precious metals without excessive balance sheet risk.
5. Canadian Utilities Limited (TSX: CU)
Canadian Utilities, a subsidiary of ATCO Ltd., is one of the country’s most stable utility providers. Unlike many utilities that rely heavily on debt financing, Canadian Utilities maintains a debt-to-equity ratio below 1, supported by consistent cash flows from regulated operations.
With a diversified portfolio spanning electricity, natural gas, and infrastructure, the company has built a reputation for financial prudence. Its strong equity base ensures resilience against rising interest rates, while its steady dividend policy continues to attract long-term investors. Canadian Utilities exemplifies how essential service providers can thrive with conservative leverage.
Why These Companies Stand Out
These five firms represent diverse sectors—technology, engineering, mining, and utilities—yet share a common trait: financial resilience through low leverage. In an era of high interest rates and economic uncertainty, companies with strong equity positions and limited debt exposure are better equipped to weather downturns.
Investors benefit from reduced risk of dividend cuts, fewer refinancing challenges, and greater flexibility for growth initiatives. Moreover, these companies’ strong recent returns demonstrate that financial discipline does not come at the expense of profitability.
Risks and Considerations
While low debt-to-equity ratios are generally positive, investors should remain mindful of sector-specific risks. Mining companies, for example, are sensitive to commodity price fluctuations, while utilities face regulatory challenges. Additionally, companies with very low debt may miss opportunities to leverage cheap financing for expansion.
Therefore, while these firms exemplify balance sheet strength, investors should complement ratio analysis with broader due diligence, including cash flow stability, industry outlook, and management strategy.
Conclusion
The Canadian market offers a range of companies with attractive debt-to-equity profiles, but Celestica, AtkinsRéalis, K92 Mining, Wesdome Gold Mines, and Canadian Utilities stand out in 2025. Their ability to combine low leverage with strong returns makes them prime candidates for investors seeking stability and growth.
As Canada continues to navigate a high-interest-rate environment, these companies demonstrate that financial discipline remains a cornerstone of long-term success. For investors focused on risk-adjusted returns, they represent some of the best opportunities on the TSX today.
