The oath ceremony happens over Zoom. The list of documents you need will be listed in the oath email but basically keep the following ready -
2 pieces of ID
COPR
PR card
A good pair of scissors
For a full list of documents, check your oath email when you receive it (You might receive the oath email about a week to 10 days before the ceremony.
You will have to cut your PR card into 4 pieces in front of camera at the end of the ceremony.
Good luck.
