Implications of Canada’s new Anti-Spam Law


Canada Says No to Spam

To conform with Canada’s new Anti-Spam Legislation (CASL), coming into effect July 1, 2014, McGill IT Services is increasing efforts to reduce the risk of spam on our mailing lists. We have tightened the regulations on the two types of email distribution lists currently supported.

1) LISTSERV mailing lists are those with addresses of the form xxx [at] The regulations for Listserv lists have been updated as follows:

  • The allowed period of inactivity of a Listserv has been decreased from 24 months to 12.
  • Listserv lists must be set up to include an “unsubscribe” link in all communications sent to the list.
  • New Listserv lists will be set up as “moderated” by default.

2) Exchange distribution lists are found in McGill’s Global Address List and their membership is based on McGill's Active Directory (AD) groups. The majority of these lists already require "authentication", meaning that messages sent to the list must come from McGill email accounts that have been properly configured to authenticate using McGill Email and Password credentials. Over the summer we will be ensuring that all such lists require authentication, except in special cases where emails need to be sent from entities outside McGill or directly from IT systems (e.g., automated notifications).
