If your study permit's expiry date was only set to match your old passport's expiry (not your actual program end date), and you've since renewed your passport, you'll need to update your study permit — but this is different from a normal study permit extension.
What group members advised:- You don't need to show full proof of funds again for this type of update. Because it isn't a substantive extension of your studies (your permit was only cut short by the old passport's expiry date, not by your program ending), the funds requirement that applies to genuine extensions doesn't apply here in the same way.
- If you want to submit supporting documents anyway, fee payment receipts or a GIC/savings deposit certificate are reasonable choices — but they're optional add-ons, not a requirement.
- Submit the application well before your current study permit expires, referencing your new passport, so there's no gap in your legal study status while it's processed.
In short: treat this as a passport-driven correction to your study permit's expiry, not a new extension application, and don't assume a full new round of financial documentation is needed.
