I had some same situation as yours, so I will try to give you some advices here, BUT I AM NOT PROFESSIONAL.
It seems that:
you have/had a PGWP visa, (Is it still valid now? what's your status now?)
and you deliver the TR to PR application under International Graduate stream on May 7th, 2021
you have 3 updates, AOR March 31 2022, ADR March 23, 2022, ADR August 26 2022
you received the email from IRCC that about the work permit extension in August, 2022. this policy said that the work permit will send to you by mid October 2022.
You have no PR confirmation also work permit extension right now.
About your PR confirmation:
It's a normal situation that you are still waiting, me too, there are lots of people still waiting for this stupid PR confirmation. Since it is a temporary policy so it has no guarantee processing time.
And you can not get the newest updated status from IRCC website.
You may try to call IRCC or try to get a GCMS notes from IRCC to have your app status. There are lots of people here are waiting for the background check, or some other results. Hopefully the worst situation is that all the TR to PR case would be done before the end of this year. If you try to read more pages in this thread, you will get some useful analysis and informations about it.
Then all we can do is waiting and with patient.
About your work permit:
IRCC fucked this work permit auto extension program. You have to help yourself right now.
I had the same situation, received the email from IRCC in August 2022, and nothing mail to me.
IRCC they really want to do some good things, try to save the money and time for those people need work permit extension under TR to PR program. But they did a super terrible thing if this work permit did NOT send to those already got the email. There is a guy that in this situation keep waiting and forgot maintain his status here. his work permit finally expired.
My previous work permit was expired on Dec 31, 2022, I contact IRCC in early December 2022, they said that they had send all the work permit in October 2022, if I did not receive it, then i am not qualify. WTF, if i am not qualify, why you IRCC send me the email?
I believe that there are lots of similar cases, like the situation of us. Because all my family health card, visa, CCB ... all depends on it. I submit another work permit extension case in Dec 2022, then I have to wait it, PR and work permit.
Seriously, We should sue IRCC about that, maybe later, together.
So what's your situation right now? you still have a valid visa here to maintain your status? If so, you can apply work permit extension by yourself. If not, I have no idea about that, it is better that find a real immigration consultant or lawyer.
Wish those helps. best luck.
