Canada Introduces New Sustainability Standards: Implications for Regulators and the Path to Structured Digital Reporting

The Canadian Sustainability Standards Board (CSSB) has finally released its long-awaited Canadian Sustainability Disclosure Standards (CSDS)—a monumental step toward enhancing sustainability and climate-related disclosures in Canada. The introduction of these standards, namely CSDS 1 (General Requirements for Disclosure of Sustainability-related Financial Information) and CSDS 2 (Climate-related Disclosures), brings Canada closer to aligning with global sustainability reporting frameworks, such as the International Financial Reporting Standards (IFRS) S1 and S2. However, while these developments set an important regulatory precedent, there remains a critical element missing in the conversation: the need for a mandated digital taxonomy to ensure that the high-quality disclosures are transformed into accessible, comparable, and actionable data. 

As regulators in Canada and globally work to support transparency and accountability, the absence of a digital taxonomy in the CSSB’s standards presents both a challenge and an opportunity to drive the future of structured sustainability reporting. This blog delves into the implications of CSDS 1 and CSDS 2, the role of digital taxonomies, and the potential for Canadian regulators to lead in the adoption of global best practices. 

The release of CSDS 1 and CSDS 2 marks a critical moment in Canada’s sustainability journey. These two standards, available as part of the CPA Canada Handbook – Sustainability, provide a framework for businesses to disclose sustainability-related financial information, with CSDS 1 focusing on general sustainability disclosures and CSDS 2 centering on climate-related disclosures. The standards are voluntary unless mandated by regulators or the Canadian government. 

These disclosures are modeled after the International Sustainability Standards Board (ISSB)’s IFRS S1 and S2, ensuring that Canadian businesses align with global reporting frameworks. This alignment is particularly important for maintaining consistency across jurisdictions and facilitating comparability for investors, regulators, and stakeholders. 

The CSSB’s standards will also serve as a foundation for enhancing transparency and enabling businesses to provide stakeholders with clear insights into their sustainability practices and climate-related risks. However, while these standards provide a robust foundation for reporting, they are incomplete without a structured framework for digital reporting. 

Recognizing that the implementation of sustainability reporting standards may pose challenges for Canadian businesses, the CSSB has introduced several transition relief measures to support companies during the shift. These measures include: 

1. Delayed Effective Dates: The effective dates for CSDS 1 and CSDS 2 are set to be one year later than their global counterparts, IFRS S1 and S2. This delay allows Canadian businesses additional time to prepare for compliance and integrate sustainability reporting into their existing systems. 
2. Phased Reporting Requirements: Reporting on matters beyond climate change, including Scope 3 greenhouse gas (GHG) emissions, will be phased in over a longer period, giving businesses the opportunity to build the necessary data collection and reporting frameworks. 
3. Extended Relief for Financial and Sustainability Reporting Alignment: Canadian entities will have two additional years to align their financial and sustainability reporting, with deadlines extending to nine months following the first year-end and six months for the second and third years. 
4. Delayed Reporting on Scope 3 GHG Emissions: The timeline for reporting on Scope 3 emissions will be three years longer than the timeline prescribed by IFRS S2, providing businesses more time to develop comprehensive GHG emissions reporting. 
5. Extended Relief for Scenario Analysis Reporting: Entities will have three years of relief for the quantitative aspects of scenario analysis data reporting, allowing companies to refine their approach to assessing and reporting climate-related risks. 

These measures reflect the CSSB’s understanding of the challenges Canadian businesses face when implementing new reporting standards, particularly for smaller entities or those in the early stages of sustainability data collection. 

While the CSDS 1 and CSDS 2 standards are a positive step toward improved sustainability disclosures, there remains a significant gap in the regulatory framework: the absence of a mandated digital taxonomy. The ISSB has already highlighted the importance of digital reporting in making sustainability disclosures accessible, comparable, and actionable. Digital taxonomies, such as XBRL (eXtensible Business Reporting Language), are key to ensuring that data can be efficiently structured and analyzed across jurisdictions. 

At present, the CSSB has not introduced a digital twin of its sustainability disclosure standards. This is a missed opportunity, as digital taxonomies play an essential role in turning narrative-driven disclosures into structured data that can be easily accessed and analyzed by regulators, investors, and other stakeholders. Without a digital taxonomy, Canadian companies may face challenges in meeting the growing demand for real-time, structured, and comparable sustainability data, limiting the impact of their disclosures. 

For regulators, this gap represents a significant hurdle in realizing the full potential of sustainability reporting. While the standards provide a comprehensive framework for disclosure, the lack of a mandated digital taxonomy limits the ability to process and analyze the vast amount of data generated by these reports. This makes it harder to ensure that disclosures are both discoverable and actionable—a critical aspect of fostering transparency and accountability in sustainability reporting. 

The lack of a mandated digital taxonomy in the CSSB’s standards stands in contrast to global trends that emphasize the importance of structured, machine-readable data in sustainability reporting. The ISSB and other international bodies have already recognized the role of digital taxonomies in facilitating comparability and transparency, which is vital for the integrity of sustainability disclosures. Without these digital frameworks, companies may struggle to provide data that is easily usable by regulators, investors, and other stakeholders, undermining the goals of sustainability reporting. 

Countries that have adopted digital taxonomies, such as the European Union with its ESEF (European Single Electronic Format) or the United States with its XBRL-based reporting, are reaping the benefits of structured data. These taxonomies ensure that sustainability data can be easily compared, analyzed, and audited, offering regulators a more efficient way to oversee corporate sustainability performance. 

For Canadian regulators, adopting a digital taxonomy aligned with the ISSB’s global baseline is a logical next step. A digital twin of the ISSB taxonomy would allow Canada to align with global best practices, ensuring that the data disclosed under the CSDS 1 and CSDS 2 standards is structured in a way that is compatible with other jurisdictions’ regulatory frameworks. This would not only enhance the comparability of Canadian disclosures but also foster greater transparency and accountability in the Canadian market. 

To address the missing link in Canada’s sustainability reporting framework, Canadian regulators should consider the following actions: 

1. Adopt a Mandated Digital Taxonomy: Canada should introduce a mandated digital taxonomy for sustainability reporting, ideally aligned with the ISSB’s taxonomy. This would ensure that sustainability data is structured in a machine-readable format, facilitating easier access, comparison, and analysis by all stakeholders. 
2. Promote Global Harmonization: As sustainability reporting standards evolve, Canadian regulators should work towards harmonizing their standards with global frameworks, particularly the ISSB. This will ensure that Canadian businesses remain competitive and can meet international investor expectations. 
3. Encourage the Use of Structured Data: Canadian regulators should encourage companies to adopt structured data formats, such as XBRL, for their sustainability disclosures. This will enhance data integrity, making it easier for regulators to monitor compliance and for investors to make informed decisions. 
4. Provide Guidance on Digital Reporting: To ensure that businesses are prepared for the digital future of sustainability reporting, regulators should provide clear guidance on how to implement and use digital taxonomies effectively. This will support companies in transitioning to digital reporting and help them meet evolving regulatory requirements. 

Canada’s introduction of the CSDS 1 and CSDS 2 standards is a significant step forward in aligning with global sustainability reporting practices. However, the absence of a mandated digital taxonomy presents a challenge that regulators must address to fully realize the potential of these standards. By embracing digital reporting and adopting a digital taxonomy aligned with global best practices, Canadian regulators can enhance transparency, comparability, and usability in sustainability disclosures. This will not only improve regulatory oversight but also support the transition to a more sustainable and accountable corporate landscape. The time for action is now—Canada has an opportunity to lead by example and set the stage for a more digitally-enabled future in sustainability reporting.
