You'll have to be physically present in Canada during the interview, even if the interviews being conduced these days are online (over MS teams).
Generally, the only documents you'll be requested are all pages of your passport. If there are any stamps that are not in English or French, you'll have to get a certified translation for those.
Depending on your case (residing abroad), there might be other additional documents requested to prove residency in Canada.
Good luck and all the best.
Thanks so much! Do you know how soon after the test this interview is usually held?
