CASL (Bill C-28) Conformity: Consent Duration

Manage the consent duration

Canada's Anti-Spam Legislation (CASL) sets out rules concerning the duration of the consent, rules that apply to all new relationships established after the Act came into force on July 1, 2014.

Implied consent duration

A business relationship exists when a person buys a product or service from the sender, is bound by a contract, has bartered goods, and so on. Mailings are permitted throughout the relationship and up to 24 months after the relationship has ended.

An existing non-business relationship is one which an association, club or other organization maintains with its members. The consent duration is also limited to 24 months after the termination of the membership or the date of the last contribution.

For people who have given you their email address in an information request or business meeting, you have six months after the request date or meeting to send an electronic message.


  • The Anti-Spam Law does not immediately apply to business or non-business relationships that existed before it came into force on July 1, 2014. You have three years following its enactment to obtain the express consent of these contacts, even if the relationships ended more than 24 months ago.

Express consent duration

When a recipient provides his or her express consent, this consent is valid until the recipient withdraws it. However, all messages must include an unsubscribe mechanism that should be simple, quick, and easy to use and allows the recipient to withdraw his consent.

With these rules on consent duration, you have to manage the period during which you can send your communications. Dialog Insight has designed the perfect tool to meet these requirements.
