Canadian Sustainability Disclosure Standards (CSDS): Canada’s CSDS: New National Sustainability & Climate Disclosure Standards

Summary

The Canadian Sustainability Disclosure Standards (CSDS) are a new national ESG and climate-disclosure framework launched by the CSSB in December 2024. Composed of CSDS 1 (general sustainability financial-reporting) and CSDS 2 (climate-related disclosures), the standards require companies to disclose material sustainability risks and opportunities, value-chain impacts, climate-related risks, and greenhouse gas emissions (Scopes 1, 2, and, when material, 3). Effective for fiscal years beginning 1 January 2025, CSDS remains voluntary for now, pending potential regulatory adoption by securities or banking regulators. Transition reliefs allow delayed disclosure of Scope 3 emissions and quantitative scenario analysis. As Canada moves toward a net-zero economy, CSDS represents a key step to harmonise ESG reporting with global standards while adapting to the local context. Early voluntary adoption is seen as a strategic advantage for investor transparency and risk management.

Details

Jurisdictions
  • Canada
Exemptions

CSDS is currently voluntary; obligations apply only to organisations that choose to adopt the standards.

Criteria:

Identify and disclose material sustainability-related risks and opportunities.

Report governance processes for sustainability oversight.

Explain how sustainability factors influence strategy, business model and resource allocation.

Disclose risk-management processes for sustainability and climate risks.

Publish metrics and targets used to monitor performance, with transparent methodologies.

Provide complete climate-related disclosures in line with CSDS 2, including GHG emissions, resilience assessments and transition strategies.

Cover value-chain impacts where material.

Exceptions:

CSDS does not legally apply to any organisation unless voluntarily adopted or mandated by regulators in the future.

Smaller private companies and SMEs are unlikely to fall within early regulatory scoping.

During the transition period, adopters may delay Scope 3 emissions, quantitative scenario analysis and other data-heavy disclosures.

Organisations may apply different sustainability frameworks if legally permitted and more suitable to their operational context.

What’s Required

The Canadian Sustainability Disclosure Standards establish a national framework for consistent, decision-useful sustainability and climate disclosure. Organisations that adopt CSDS must report material sustainability-related financial information, covering governance, strategy, risk management, performance metrics, and targets.

CSDS 1 sets the overarching principles for materiality, value-chain boundaries, disclosure structure, and information quality. CSDS 2 adds specific climate-related disclosures, including physical and transition risks, GHG emissions (Scopes 1, 2, and material Scope 3), climate targets, transition plans, resilience analysis, and scenario assessment.

Disclosures must explain how sustainability and climate risks may reasonably affect the organisation’s financial position, performance, and cash flows over the short, medium, and long term.

Important Deadlines

  • Effective date: For annual reporting periods beginning on or after 1 January 2025.

  • Transition reliefs:

    • Scope 3 emissions disclosure may be deferred for three years.

    • Quantitative climate scenario analysis may be deferred for the initial years.

  • No compulsory adoption date, as regulators have not yet mandated CSDS.

Current Status

  • CSDS 1 and CSDS 2 were published in late 2024 by the Canadian Sustainability Standards Board.

  • The standards are fully developed but currently voluntary, as the CSSB does not have regulatory enforcement authority.

  • Securities regulators paused their mandatory climate-disclosure rule in 2025 but continue evaluating alignment options with CSDS.

  • Early adoption is increasing, especially among larger companies and financial institutions preparing for future regulation and investor expectations.

Penalties for Non-Compliance

  • As CSDS is voluntary, there are no legal penalties for not adopting it.

  • If regulators later mandate the framework, sanctions could include administrative fines, disclosure restatements, or impacts on listing requirements.

  • Market-driven consequences (investor pressure, reputational risks, ESG rating impacts) may apply to organisations failing to meet evolving transparency expectations.

Examples of Known Violations

As of late 2025, no violations or enforcement actions related to CSDS have been recorded, because the standards remain voluntary and not subject to regulatory sanctions.
