Officer said "
CPCCVExtcom@cic.gc.ca" - I did not hear an underscore. And clearly, he said "CPCCV".
(Legit one is
CPCV_Extcom@cic.gc.ca)
In my understanding, someone is sending fake e-mail messages (AIP) claiming to be from IRCC. They probably used the "
CPCCVExtcom@cic.gc.ca" as the contact name – but the actual reply address is obviously not IRCCs. Similar with phishing emails.
