There’s no such thing as an FSW draw. The all program draw which was stopped last year in December includes all express entry streams and might continue from next year.There are some chances of one FSW or CEC draw based on immigration minister decision.
I think some people received ITA this year might not responded due to covid travel restrictions or personal situation changes due to covid.
So, any remaining ITA / ITA not responded may lead to one FSW(or CEC) draw on year end. So that, those application will be received and processed next year.
