Thanks for the reply ,You could again reply to that email with your updated information because that email is not do not reply one email. So they can read it. Also, fill the webform about this Ircc will notice this issue.
Also, portal client email department and IRCC both are different body and work individual and eventually they send IRCC to your information and IRCC take decision.
Or if you are planning to come back in Canada within few days then it will be fine.
Will there be any problem for my application due to this ? I am bit worried about this
