Which law requires commercial electronic messages to obtain prescribed consent and provide an unsubscribe mechanism within 10 business days?

• A. Privacy Act
• B. Consumer Protection Act
• C. Anti-spam legislation
• D. Data Privacy Regulation

Answer: (C)

Canada’s anti-spam legislation (CASL) is the rule described here. It specifically regulates commercial electronic messages by requiring obtained consent before sending them and by mandating an unsubscribe mechanism that works, with the sender stopping messages within 10 business days after an unsubscribe request. This framework exists to curb unwanted spam while allowing legitimate communications. The Privacy Act deals with how the federal government handles personal information, not marketing messages; the Consumer Protection Act covers broader unfair practices but doesn’t lay out the precise consent and 10-day unsubscribe requirement; a Data Privacy Regulation isn’t the applicable Canadian statute for this area. So the described requirements come from anti-spam legislation.
