Did you get a response from this email address? IRCC.DN-CITIZENSHIP-CEREMONIES-RN-CITOYENNETE-CEREMONIES.IRCC@cic.gc.caThanks, I received the original invite from the Mississauga office, but I have been yet unsuccessful receiving a response from them. So I tried the email in my original post.
Thanks re: tracker, just checked and no update, it doesn't even say that my ceremony was cancelled due to me not being available at the time.
