AOR and auto-generated emails sent to you by the system 24hrs after the intake officer reviews your application - I have no idea if its morning or night but most auto-generated emails are sent in a specific time period depending on the system limitation (IRCC might have some limit that says send 10k AOR 3 time daily or whatever, to not overwhelm the system) I only know this because I read an operation manual once of how the internal intake officers review application and entered them into the system, and what they have to do in order to generate a AOR and then once generated they download it and send via mail, or send via email if you have an email on file.
Furthermore, you will need to wait for a few more weeks as IRCC is Processing AOR for applications received on Oct 3 at the moment.
Last, even after you get the AOR, you will still have anxiety and checking every email will feel like it should be from IRCC lol so that never goes away until you say that oath and get that certificate in yo hand.
Good luck
Ohh to also answer your question I got my AOR at 10am in the morning back when I got mine
