Introduction

As global demand for high-quality sustainability information accelerates, countries are moving quickly to align with emerging international standards. Canada has taken a leading role by establishing the Canadian Sustainability Standards Board (CSSB), a national body that works in tandem with the International Sustainability Standards Board (ISSB). The CSSB ensures that sustainability disclosure in Canada meets global expectations while remaining relevant to Canadian economic, social, and environmental contexts. As Canadian businesses face growing pressure from regulators, investors, and international supply chains, the CSSB is poised to become the cornerstone of ESG transparency in the region.

The Birth of the CSSB: Canada’s Answer to Global ESG Expectations

The Canadian Sustainability Standards Board was officially launched in June 2023 under the governance of the Financial Reporting & Assurance Standards Canada (FRAS Canada). Its mission is to support the adoption of sustainability disclosure standards in Canada, ensuring compatibility with the IFRS Sustainability Disclosure Standards developed by the ISSB. The CSSB is uniquely designed to serve Canada’s bilingual and regionally diverse business environment, conducting extensive consultations with Indigenous communities, industries, and provincial governments. By embedding transparency and regional sensitivity into its mandate, the CSSB aims to make ESG reporting both meaningful and manageable for Canadian companies.

From ISSB to CSSB: Translating Global Standards for Canadian Realities

While the CSSB aligns closely with the ISSB’s global standards (notably IFRS S1: General Requirements and IFRS S2: Climate-Related Disclosures), it also addresses issues specific to the Canadian context. This includes the integration of Indigenous rights, localized climate risks, resource-dependency in key sectors (like oil and gas, mining, and forestry), and biodiversity impacts across northern territories. For example, Canadian mining firms may need to disclose more granular data on water use and tailings management than their international peers. The CSSB serves as a vital translator of global ESG frameworks into operational guidance for Canadian issuers.

Table: ISSB vs. CSSB Focus Areas

Topic	ISSB (IFRS S1/S2)	CSSB Adaptation
Climate Risk	Global frameworks (TCFD-based)	Northern infrastructure risks emphasized
Indigenous Engagement	Not explicit	Required consultations and impact reporting
Biodiversity	Generalized	Specific focus on boreal forests and habitat loss
Scope 3 Emissions	Encouraged	Phased guidance based on industry readiness

CSDS Reporting Requirements

The Canadian Sustainability Disclosure Standards (CSDS) are Canada’s national sustainability disclosure standards, developed by the CSSB to reflect international best practices while tailoring requirements to Canadian business, regulatory, and environmental contexts.

CSDS 1 sets the foundation for sustainability reporting across all relevant topics. It requires entities to disclose:

• Material sustainability-related risks and opportunities
• Governance structures overseeing these topics
• Strategies and risk management processes in place
• Metrics and targets used to track performance

These disclosures align with the four pillars of the TCFD (governance, strategy, risk management, and metrics & targets), but are extended to cover broader ESG categories beyond climate alone.

CSDS 2 focuses exclusively on climate-related disclosures. Entities must report:

• Climate governance and oversight
• Transition plans and net-zero targets (if applicable)
• Greenhouse gas emissions across Scope 1, 2, and, over time, Scope 3
• Climate resilience using scenario analysis
• Financial effects of climate risks and opportunities

Some disclosures—especially scenario-based quantitative data—are subject to phased implementation, giving entities time to prepare.

Implementation Timeline

For entities choosing to adopt the CSDS as early as January 1, 2025, the CSSB has outlined a phased compliance schedule. While transitional relief is granted for certain quantitative requirements, this may affect related disclosures under CSDS sections 2.15 to 2.17, which concern the financial impact of sustainability factors.

Fiscal Year	Reporting Year	Topics Covered	Scope 3 Emissions	Timing of Reporting	Comparatives	Quantitative Scenario Analysis
2025	2026	Climate only	Not required	Within 9 months of year-end (or 6 months with interim report)	Not required	Not required
2026	2027	Climate only	Not required	Within 6 months of year-end	Climate only	Not required
2027	2028	All topics	Not required	Within 6 months of year-end	Climate only	Not required
2028	2029	All topics	Required	Same time as the financial statements	All topics	Required

Canada’s financial regulators are also moving in parallel. The Office of the Superintendent of Financial Institutions (OSFI) has issued climate-related guidelines for federally regulated financial institutions, while the Canadian Securities Administrators (CSA) is working to embed CSDS-compliant disclosures into public company reporting. This coordinated approach is expected to ensure broad alignment and comparability across sectors.

Sectoral Impacts: Energy, Finance, and Natural Resources

Canada’s most carbon-intensive and resource-dependent industries will be among the most affected by CSSB disclosures. In the energy sector, oil and gas firms are under increasing scrutiny from both Canadian and international investors to align with Canada’s Net-Zero Emissions Accountability Act. Financial institutions must integrate CSSB-aligned climate risk disclosures into lending and investment portfolios, building on OSFI’s B-15 climate risk management guidelines.

In natural resources, companies will need to report on land use, biodiversity, and water risks-factors that are particularly material in mining, forestry, and agriculture. The CSSB is working closely with industry groups to ensure these metrics are feasible yet robust.

Conclusion: Why the CSSB Matters for ESG Leaders

The creation of the Canadian Sustainability Standards Board marks a significant step toward ESG standardization and transparency across Canada. By adapting global frameworks to local realities, the CSSB enables Canadian companies to align with international best practices without losing sight of regional needs. For ESG leaders, embracing CSSB-aligned disclosures offers a strategic advantage: enhanced investor trust, supply chain readiness, and long-term resilience. As the world moves toward harmonized sustainability reporting, Canada’s approach could serve as a model for other nations balancing global compliance with domestic impact.
