All Concordia University students can obtain a university email address.
Some professors or teaching assistants will only accept emails sent from a Concordia email as stated in the course outlines. It is also highly recommended to use your Concordia email address in your eConcordia account to avoid issues with receiving course announcements or emails from your professor.
All active Concordia students have access to a free Concordia email, see the page below for information on how to activate your Concordia email.
