Hi YYZguy416
Yes, I called CIC call centre and the automated telephone system just said my application was submitted on March 20th. There is no more additional message. Also my CIC account doesn't have any message.
I have been trying to reach a staff at the call centre, but it's always busy and I haven't been able to talk with them yet.
As you said, if I should've received it by now, I might have made a mistake of my application, so I'll keep on trying to call them.
Thanks.
