Finally attended my oath ceremony!
See full timeline below.
Note that while waiting, I renewed my PR card (applied in June and received new card in November). Though I received my initial oath invite in November, I had to reschedule my oath date because I had to travel during Christmas and couldn't wait for the citizenship certificate to apply for new passport (too tight and uncertain timeline).
I informed CIC when I got back and had to follow up twice via email before receiving my new oath date in March.
