@Sohaib89 i did what you told me I sent email to the invite I received and below what they respond :
——-
Please note that we offer the possibility of receiving an electronic certificate to certain people who submitted their application before January 4, 2023.
Your permanent resident card will need to be cut during the ceremony. Consequently, if you want to travel without worries, it would be better to postpone your ceremony until after your stay outside Canada. You will be called again at a later date according to our processing times.
For more information, you can contact the IRCC Call Center at 1-888-242-2100

I feel it’s a generic email what do you think ?
