The computer program provisions in Canada’s anti-spam law (CASL) are very hard to apply in practice. One of the most difficult interpretive challenges involves determining what the phrase “install or cause to be installed” means. CASL only applies where a person installs or causes to be installed a program on someone else’s computer. The CRTC released a Guideline that attempts to clarify what CASL means by that phrase. In information sessions last week to IT.Can and ITAC members, Dana-Lynn Wood and Lynne Perrault of the CRTC attempted to provide even further guidance on this issue.
