Thank you for your response. While I can manually configure the signature, an unsubscribe mechanism is not provided as per subsection 11(1).
11 (1) The unsubscribe mechanism referred to in paragraph 6(2)© must
(a) enable the person to whom the commercial electronic message is sent to indicate, at no cost to them, the wish to no longer receive any commercial electronic messages, or any specified class of such messages, from the person who sent the message or the person — if different — on whose behalf the message is sent, using
(i) the same electronic means by which the message was sent, or
(ii) if using those means is not practicable, any other electronic means that will enable the person to indicate the wish; and
(b) specify an electronic address, or link to a page on the World Wide Web that can be accessed through a web browser, to which the indication may be sent.
I would also suggest an automatic signature that can be edited by the administrator be added so that these violations aren’t accidentally made by journals.
