Thank you for your reply.Hi Japonesa,
I believe if you have not gone back to your home country IRCC would not ask you to resubmit your PCC as it would be still valid. I have submitted my application on Jan 15 2018. I got the request for PCC and Schedule A right after i received AOR(as i did not submit PCC with app).
If you have received AOR and Schedule A request. Its likely that your PCC is valid and next would be medical.
Yes after my arrival to canada i have never gone back yet to my home country.
we already got aor from cic on july 7.
And in our application, we already included schedule a and pcc so when we got the aor there were no documents requested. I hope everything goes well.
For now we are also waiting for owp to be approved.
