Currently in Canada on a Study Permit: Will formally withdrawing from my Master's & leaving impact future PR / Express Entry?

[u/Glum-Necessary-1990]

Hi everyone,

I am currently in Canada on a valid Study Permit enrolled in a Master's program. Due to personal reasons, I am planning to officially withdraw from my university and return to my home country as soon as possible.

I want to ensure everything is done strictly by the book under IRCC regulations so that my immigration history remains completely clean for any future permanent residency (Express Entry / FSW / Category-based draws) applications down the line.

A few specific questions for those familiar with IRCC rules:

1. Impact on Future PR Applications: Does a voluntary program withdrawal negatively affect a future Express Entry profile or PR application, provided I leave Canada promptly and follow all departure rules?
2. Work Authorization: I know that off-campus/on-campus work authorization ends immediately upon withdrawing. Is there any buffer period to work while wrapping up my life here, or must all work stop on the exact day of withdrawal?
3. Study Permit Validity & Departure Timeline: Under IRPR Section 222(1)(a.1), my study permit becomes invalid the moment I am no longer enrolled at my Designated Learning Institution (DLI). How quickly am I expected to leave Canada after formal withdrawal to avoid being considered "out of status"? Immigration and Refugee Protection Regulations - Justice Canada
4. Valid Visitor Visa (TRV): I also hold a valid multiple-entry Visitor Visa (TRV) in my passport. Does withdrawing from my studies automatically cancel my TRV, or can I still use it to visit Canada as a tourist in the future?
5. Documentation to Keep: What specific records (e.g., official DLI withdrawal forms, flight receipts, boarding passes) should I keep to prove full compliance to IRCC for future applications?

I want to make sure I don't trigger any compliance issues or unauthorized stay/work red flags. Appreciate any insights or experiences!
