Implied Consent: In some cases, implied consent may apply if there is an existing business relationship, such as a customer purchasing goods or services. However, implied consent has strict time limits—typically 24 months—and it cannot be assumed for SMS marketing unless the individual has specifically provided their phone number for commercial messaging.
This means that the company’s name, physical business address, and other details must be included in the message, so recipients can easily determine who is sending the message.
Opt-Out Mechanism: Every SMS message Canada Phone Number List must contain an easy, functional method for recipients to opt out of receiving further messages. This is typically done by offering a clear instruction such as "Reply STOP to unsubscribe."

No Misleading Information: CASL prohibits the use of misleading or deceptive information in SMS marketing. This includes the subject line, content, and sender details. Marketers must ensure their messages are truthful and do not lead recipients to believe they are being sent from a source other than the actual sender.
