Once your PGWP expires, you stop working unless you have the approved LMIA and closed work permit or have ITA through Express Entry. The closed work permit is employer specific so you can't work for anyone else. On your PGWP, you can work for anyone.pgwp expires on sep 2022.
even if i am working with the same employer who will apply for my LMIA i cannot work till i get my closed wp?
