Please note that beginning in late June 2021, outgoing email messages sent from the Canadian Intellectual Property Office (CIPO) will be changing from the username@canada.ca domain to the username@ised-isde.gc.ca domain. We encourage you to update your email address book to avoid messages being sent to your Junk Email folder.
Please note that this is only the case for CIPO's outgoing messages. Despite the outgoing email domain name change, CIPO accounts will be still able to receive messages sent to the username@canada.ca domain (as well as the new username@ised-isde.gc.ca domain).
