The role of the corporate secretary in Canada has never been more demanding. In 2026, Canadian reporting issuers face an evolving compliance landscape across cybersecurity disclosure, ESG reporting, AI governance, and the ongoing modernization of securities regulation through the Canadian Securities Administrators (CSA). At the same time, the CBCA and provincial corporate acts are updating governance requirements that directly affect how corporate secretaries manage board operations.
This guide is a practical toolkit — covering the specific regulatory instruments, filing obligations, and governance best practices that Canadian corporate secretaries must manage in 2026.
The CSA has increased scrutiny of environmental, social, and governance disclosure by reporting issuers. Through Staff Notice 51-358, the CSA expects:
Corporate secretaries must ensure that cyber risk disclosure in the AIF and MD&A is tailored and entity-specific. The CSA challenges issuers whose disclosure reads as generic risk factor boilerplate.
All filing obligations flow through SEDAR+, which replaced the legacy SEDAR system. Corporate secretaries should ensure their filing processes are updated for the new platform, including management information circular requirements.

Under the CBCA, directors and officers with a material interest in a contract or transaction must disclose the interest at the earliest opportunity. The corporate secretary must: record the disclosure in the board minutes, ensure the conflicted director abstains from voting, and maintain a register of all disclosures.
CBCA corporations must file an annual return with Corporations Canada. The corporate secretary typically manages this filing, ensuring director information, registered office address, and corporate details are current.
Federal corporations and those operating in Quebec may have obligations to provide governance documents, shareholder communications, and proxy materials in both English and French. The corporate secretary must coordinate bilingual document production and ensure regulatory filings comply with language requirements.
