Hello everyone, I thought I will provide my own update as well. I submitted a single application online back in July. The online portal showed that it was submitted on July 13th (I was ready to send my application 2 weeks prior but I was struggling with the online form as you can see in my previous posts in this thread). The status remained "submitted" until today, and it never changed. But I also received the PR card in the mail today (Sept 8). The expiry on the card shows Aug 31, so it was probably ready early Sept and it took around a week in the mail. I also never received an AOR and I wasn't able to find the status of my application on CAS (I even tried today). From reading all the previous comments, it seems that an online submission doesn't require an AOR because its a guaranteed submission as opposed to paper-based submission where you need to confirm receipt of the mailed forms. Just my own opinion though
Good luck to all.
