I had virtual interview while i was out of country so no issues in that, just let them know via email. The official mentioned that everything on the file is in order and the only reason for the interview was because i filed the application from outside Canada and its their standard procedure for that. My interview last for abt 15 mins out of which just 2 mins were related to document check and file related questions. Rest we were just having friendly talk and specially for having same sun sign. Lol. The official said i guarantee you now you are now officially a Canadian and your file is complete. It will be updated soon on the tracker. And they asked me abt my return plans so she can request oath ceremony after that date. I took my oath this week after returning to Canada.
Processing office - Calgary (very fast processing office, have seen many examples now, including myself)
Oath ceremony was in-person.
