I believe it means that the certificate has been processed.I had my citizenship ceremony (Scarborough) on Jun 15th, Zoom meeting. Today, status on both the tracker and old system, is Closed. Does that mean that the citizenship certificate has been couriered from Scarborough. Do we get any sort of information, after the certificate is couriered from Scarborough.
The standard delivery for the certificate is Canada Post, regular mail. I believe the only reason a certificate would be couriered is if you have requested urgent processing. In that case, I believe you're sent a tracking number. Otherwise it's just waiting to see whether the certificate will arrive in the mail.
For me, I know my certificate was mailed on Wednesday and though other mail has been delivered yesterday and today I still haven't received the certificate.
