I had sent the email to IRCC Scarborough office 2 days before the ceremony with a request to expedite the certificates. In the email I had included letter (issued on the company letterhead) stating the reasons for travel, travel dates, etc, this letter was issued by my manager.
Scarborough office replied with the following email
Good day,
Thank you for your email. There are about 5 weeks between your ceremony date and your expected travel. That is enough time to receive your certificate and get your Canadian passport. If you send us your signed oath form right after the ceremony within the regular business hours, we will issue your certificate the same day and mail it to you the following day. You can receive your certificate in about one week. Please make sure that we have your current mailing address on your file.
Alternatively, our records show that your PR card is valid until 2024/xx/xx. You can travel and return back to Canada from abroad until that date.
You can request cancellation of your ceremony date, keep your PR Card intact and reach out to us via this email thread to request to be rescheduled after you have RETURNED to Canada. You will most likely be rescheduled within 4-6 weeks from the date of your request. The rest of your family can proceed with the ceremony as scheduled.
Please let us know if you would like to proceed with cancellation of this ceremony date.
Regards,
Scarborough IRCC Team / ZBL
I replied to this email stating, I do not wish cancel my participation for the Oath Ceremony.
On Sep13, The clerk who checked our documents in breakout rooms (PR cards etc) acknowledged during the Oath ceremony that their office had received my email in which I had stated the request to expedite the certificate. She mentioned that as soon as the ceremony gets over send the signed oath forms asap and she will ensure the certificates are mailed the next business day by regular Canada Post mail. I used the opportunity to ask her if I can pick up the certificates from Scarborough office instead, she said that it is not possible because of CoViD restrictions
We followed what she suggested us to do and we got the certificates in our mailbox on Sep 16
In my honest opinion they will not consider your request since it is for a personal trip and not an emergency. But there is no harm in sending this and asking for it.
