SEC’s ESG Warning Could Influence Canada’s Next Move on Sustainability Reporting

Takeaways

• The U.S. Securities and Exchange Commission (SEC) has signaled skepticism toward integrating sustainability into financial reporting.
• Canada’s regulators may reconsider their approach to sustainability disclosure in light of this U.S. stance.
• The debate underscores tensions between reliable financial reporting and broader ESG (Environmental, Social, and Governance) goals.

The U.S. Securities and Exchange Commission (SEC) is drawing a sharper line between financial reporting and sustainability disclosure, a move that could ripple across Canadian markets.

On September 10, 2025, SEC Chairman Gary Gensler delivered the keynote address at the inaugural OECD Roundtable on Global Financial Markets, emphasizing that “high-quality accounting standards and financial materiality” form the foundation of effective securities regulation. His remarks renewed scrutiny of the balance between ESG disclosure, financial reporting, and regulatory independence.

Currently, the SEC allows foreign private issuers (FPIs), including Canadian public companies, to file financial statements using International Financial Reporting Standards (IFRS) without reconciling them to U.S. Generally Accepted Accounting Principles (GAAP). However, Gensler warned that the SEC might revisit this policy if it perceives that the IFRS Foundation’s focus on sustainability standards threatens the quality of financial reporting.

At the center of the debate is the relationship between the International Accounting Standards Board (IASB) and the International Sustainability Standards Board (ISSB), both overseen by the IFRS Foundation. Since the IFRS Foundation must now fund both boards, the SEC has urged it to prioritize the IASB’s core mission, reliable accounting standards, over sustainability initiatives.

Gensler cautioned that sustainability goals should not become “a backdoor to achieve political or social agendas,” calling such efforts “specious and speculative.” He suggested that if IFRS funding or focus drifts toward sustainability at the expense of accounting quality, the SEC could reassess its acceptance of IFRS-based reporting.

The Chairman’s remarks echoed earlier concerns voiced by another SEC Commissioner in 2021, who warned that merging sustainability standards with financial reporting could undermine objectivity and comparability for investors.

The IFRS Foundation, which relies heavily on voluntary contributions, faces ongoing funding pressures. As a result, the SEC’s watchful stance may influence how international standards are shaped, and how much weight sustainability carries in global financial reporting.

In Canada, the timing of Gensler’s comments is notable. The Canadian Securities Administrators (CSA) recently paused their work on mandatory climate-related disclosure rules. When discussions resume, the CSA may need to consider whether to align with or diverge from the SEC’s more cautious approach. The influence of the Canadian Sustainability Standards Board (CSSB) and its alignment with ISSB standards could come under closer scrutiny.

As the U.S. and Canada navigate different paths on ESG regulation, one thing is clear: The future of sustainability disclosure, and how it intersects with financial reporting, remains far from settled.
