No, I pretty much have to wait until CIC sends an AOR or processes dates after my date to know for sure. After many calls to Canada Post, it stands that more likely than not it was delivered. Due to such a high volume at the case processing center, sometimes they do not scan all the packages and some packages may get missed. The sorting facility in Mississauga does not leave packages behind, so they are required to get everything out every day. This is what I was told by the 4th supervisor yesterday.
So with that, I have to try to stay sane so early in the process.
BTW I got my Canada Post refund in the mail yesterday..... Thanks Canada Post
