CSA Proposes Amendments To Modernize And Streamline Canada's Mining Disclosure Standards

Introduction

On June 12, 2025, the Canadian Securities Administrators (CSA) announced extensive proposed amendments (Proposed Amendments) aimed at modernizing and streamlining Canada's mining disclosure regime. The Proposed Amendments would repeal and replace National Instrument 43-101 Standards of Disclosure for Mineral Projects (NI 43-101), Form 43-101F1 Technical Report (43-101F1), and the current Companion Policy 43-101CP to NI 43-101 (Companion Policy), and include consequential amendments to certain other existing instruments and forms.

The Proposed Amendments would mark the first significant update to Canada's mining disclosure regime in 14 years and are intended to update and enhance the disclosure requirements for mineral projects without introducing unnecessary regulatory burden.
