New Canada Email Law – All Emails Must Include an Unsubscribe Link


Canada has one of the most strict and in-depth email laws in the world – the Canada Anti-Spam Legislation (CASL).

CASL requires all commercial electronic messages to include an unsubscribe mechanism, this applies to individuals and organizations sending emails into and out of Canada.


The unsubscribe mechanism must:

  • Be clear and prominent
  • Have no cost to the recipient
  • Be readily available via the web
  • Be valid for at least 60 days after the email has been sent
  • Account for new unsubscribes within 10 business days.




Since July 1, 2014, violations of CASL have resulted in penalties of up to $1 million per violation for individuals and up to $10 million for organizations. From July 1, 2017, violations of CASL have been the subject of a private right of action by any affected individual or organization and can result in awards of compensatory damages and a private fine of up to $200 per message or $1 million per day.

For the further information about this Canada email law, read the complete ACT here, refer to point 11 for details regarding the unsubscribe requirement.
