Well, first of all, congrats on becoming a Canadian citizen.Thank you, yes, they have been emailed. And I emailed my original test one as well lol - DNVANBCISTESTS@cic.gc.ca , well in advance. C'est la vie!
FYI, Vancouver is WST-CitizenshipClient-Notification@cic.gc.ca (friend took her oath a few weeks ago, and their signature/auto-response confirms this on my end as well)
I noticed that your testing office is the same as mine, as far as the email address is concerned. This is not strictly the Vancouver office. The "BCIS" part should refer to "BC itinerant services". I am located in Interior/Northern BC, and in one of my conversations with an IRCC agent on the phone, I had been told that my file is being processed by BC itinerant services.
