Established by a group of Canadian telecommunications carriers in response to the CRTC Compliance and Enforcement Decision 2019-403, the Canadian Secure Token – Governance Authority (CST-GA) develops policies and supports industry protocols and operational procedures, designed to authenticate telephone calls and mitigate spoofing and illegal robocalling, generally referred to as STIR/SHAKEN. Through effective collaboration and administration, our mission is to ensure the successful implementation of the STIR/SHAKEN governance framework in Canada.
