Hi
Please always read FAQs in my signature. Q5 and Q6 is most relevant to your query.
Let me clear few points for everyone in future who will come and read this:
-- IRCC is not interested in your expired passport, visas, stamps, exit and entry stamps whatsoever !!
-- IRCC is not going to cross check your travel history with the Entry /Exit stamps of your passport. Personally, I have been using e-gate in UAE for entry and exits (No stamps at all) , and I have traveled between many European countries during my 3 years stay in Germany, so no entry and exit stamps, but I have mentioned those travels in my travel history.
-- The requirement is to have the scan of current and valid passport with any markings/stamps.
-- Like to OP mentioned, you are NEVER going to get ANY sort of rejection for not uploading even a single page of your expired passport !!
@al2un you are safe. You don't have any pending actions on your side. Relax !
Good luck !
