Canada's anti-spam legislation

Canada’s anti-spam legislation (CASL) is the federal law dealing with spam and other electronic threats.  It is meant to protect Canadians while ensuring that businesses can continue to compete in the global marketplace.

The Office of the Privacy Commissioner of Canada (OPC) shares responsibility for enforcing CASL with the Canadian Radio-television and Telecommunications Commission (CRTC) and the federal Competition Bureau.

When CASL came into force, it introduced a number of changes to the Personal Information Protection and Electronic Documents Act (PIPEDA). Explore the links on this page to learn more about the OPC’s responsibilities under CASL.

For full details on CASL and the roles of our partners, visit the “fightspam.gc.ca” web site.

If you are looking for information about how to deal with or prevent spam see our Spam topic page.
