That's cool - never realised citizenship applications could be processed in Fredericton.I have thoroughly checked my spam folder and all email folders using "CIC" as a keyword, but I did not receive any test email. I also reached out to IRCC customer care and they confirmed that no test email was sent according to their records. Additionally, they informed me that my application is currently being processed in Fredericton.
I wonder why ours got sent to Montreal then haha
Anyway, good luck with the rest of your application process!
