The Canadian Radio-television and Telecommunications Commission (CRTC) is responsible for enforcing CASL's rules regarding CEMs and computer programs. Since CASL came into force in 2014, CRTC has taken enforcement action against organizations and individuals who have violated CASL, and has issued enforcement decisions and accepted voluntary undertakings (settlements).
