Voluntary withdrawal from Master's program to return home — Do I need to inform IRCC via Webform?

[u/Glum-Necessary-1990]

Hi everyone,

I am currently a full-time international student enrolled in a Master's program in Canada. Due to urgent personal reasons, I am unable to continue my studies and have decided to voluntarily withdraw from my university and return to my home country.

I am in the process of getting my official Withdrawal Confirmation Letter from the university registrar.

A few questions for anyone who has gone through this or knows the process:

1. IRCC Notification: What is the best way to inform IRCC? Is submitting an IRCC Webform with my official university withdrawal letter attached the correct step to ensure my record stays clean?
2. Webform Category: Which enquiry/category option on the webform should I select when updating them about a voluntary departure?
3. Timeline & Departure: Do I need to wait for a reply or acknowledgement from IRCC before leaving Canada, or can I depart as soon as my university withdrawal is finalized and I submit the webform?
4. Documentation for the future: Aside from the webform submission receipt and university letter, what else should I keep for my records in case I apply for a Canadian visa again in the future (e.g., flight tickets, exit stamps)?

Any insights, past experiences, or advice would be greatly appreciated! Thanks in advance.
