The Fighting Internet and Wireless Spam Act (French: Loi visant l’élimination des pourriels sur les réseaux Internet et sans fil), is Canada's anti-spam legislation (also known as CASTL) that received Royal Assent on December 15, 2010.
Implied consent includes information that was acquired by engaging in a transaction with a company, or by virtue of having one's telephone number or email address listed in a public directory.
[11] No matter the type of consent, it is mandatory for senders to enable recipients to opt out of receiving messages.
[12][13] The Act added additional protections in PIPEDA to prevent companies from relying on PIPEDA exceptions relating to fraud prevention or debt collection to generate email lists by data mining or automatic crawling without consent.
[14] The Act is enforced by three organizations: the Competition Bureau, the Canadian Radio-television and Telecommunications Commission (CRTC) and the Office of the Privacy Commissioner.
