Hi..my study visa was deactivated due to the reason of deferral of intake. My intake was supposed to be September 2020, and moved to Sept 2021, which is a year difference from the original intake. I contacted IRCC through the webform, and their reply was I should reach them closer to September because they might issue a new visa, Also, they told me there’s no need to reapply for a new visa. The question I got now is when is the best time to notify them? How many months before should I notify them and how many months is the process of the issuance.
