The CSE Act

On August 1, 2019 the Communications Security Establishment Act (CSE Act) came into force. The CSE web site is being updated to reflect the changes in CSE’s authorities and the accompanying accountability and transparency measures.


The Communications Security Establishment, known as CSE, is Canada’s centre of excellence for cyber operations and is one of Canada’s key security and intelligence agencies. We are at the forefront of cyber security, operating in a technological world that is rapidly evolving. In order to continue to protect Canadians and clearly outline what CSE is permitted and authorized to do, we need updated legislation. The CSE Act will clarify how we are authorized to operate in cyber space, protecting Canadians at home and abroad from threats to our security, stability, and economic prosperity.
