When you apply for PGWP you will only get the open work permit (you will get it as letter through mail) they will ask for passport if you apply for temporary residence visa(TRV). TRV is different application and you need to pay for that visa as well.
you can see this for reference
I hope by saying "not received passport stamp request" you mean the counterfoil in the passport which is TRV. AFAIK If the TRV is not expired you do not need to apply for new one you just need to have a valid work permit (in your case PGWP) or visitor record while entering back to Canada.
*You...
Hello,
You need to apply for TRV then. Now you need to go your GC Key account and file a new TRV application and pay for the visa (if your TRV already expired). You need TRV while traveling, you need to show TRV when you enter back to Canada.
In tracker my my background verification updated a day before CoPR, Eligibility passed two weeks before first portal mail, but this can vary case to case I think.
Hello,
Just to let you know guys, I received my eCoPR today. I was PNP inland and everything went smoothly for me, wish all of you will receive good news soon.
Good luck..
My medical in GC was blank for weeks then they updated on April 5th. I think there is nothing to worry about. My medical went blank like yours when I got medical passed in the tracker.
