I applied for the PR card renewal at roughly the same time as my citizenship app. The PR card renewal was processed within the ~60 day service standard (I think this is now over 70 days per the website). Applied in August, and got the new card in October.
There was a brief period where both were "in process" on ECAS... oddly, the PR card app listed as "in process" for a couple of weeks after it was listed as mailed, and I actually had the card.
Then it disappeared from ECAS... my citizenship app is still "in process" with no progress since the FP request in early December.
Done my test today in Vancouver. I had many trips so officer said that she wants to get report from cbsa to double check everything and it's gonna take few days. For citizenship oath 2-5 months. Hopefully not more than 2.
"We sent you a notice on December 20, 2017 to appear and write the citizenship test on February 2, 2018 at 8:33 AM. The notice you will receive by mail will be your official confirmation of your appointment."
I doubt that I will receive the actual notice in the mail until after the holidays now but at least things are moving in the right direction!
And just to confirm, I did not receive an email....it was just on ECAS.
