Lots of questions recently, so I'm just going to do a summary run down rather than quoting everyone.
First, if your AOR is coming by mail, it can take up to two weeks for CanadaPost to deliver it. Trust that your eCAS status is correct, even if you haven't received the offical AOR.
If you still waiting for AOR/SA and can't access eCAS, you can call CIC for an update, but if there isn't any news expect an answer of "you have to wait until the processing times has been updated to a date beyond your application date". I'm not sure if this works for the 800 number as well, but when calling 613-944-4000, you can hit 1 three times, wait for the voice, then 1, 2, 0 under the change of address menu, to get transfered to a live operator.
wjmund, you have Sponsor Approval. Congratulations!
Finally, I didn't write any special instructions on my application, and it was fine. It's probably safer if you do, but don't stress (like I did) if you didn't.
