I came across a clarification on CES website about the received documents before Nov 12, 2020 that I share with you:
"Q. My physical academic documents were received at your office before November 12, 2020. Have you received them?
We received all mail packages submitted to our office after March 18, and up to November 20. Please note that incoming mail is processed sequentially. All mail packages received on and before November 12, 2020 are currently being processed. If you have received an automated message indicating your institutional documents have been matched to your application, it means we have received them. If you have not received an automated message by now but your tracking information shows the package was delivered before November 12, 2020, please be patient with us as we work through the mail packages to match them. afterwards, will be held at our central office, and will be delivered by The University of Toronto's Campus Mail services to our premises, once we receive permission to re-open. We will communicate with you in writing as soon as we get to your package."
