Hello All,
You need to get the PCC from whichever country you are (we all know this) - the pCC need to be not more than 3 months old when you send it to CIC (when requested) from them, if you send the PCC under the new rules and it was not 3 months old at the time you sent, they will not ask you again. I am pre-Feb 27th, they did not asked me so send the PCC and I still sent them (my mistake to send them in advance), after 1 month they completed my IA and by that time one of the PCC was more than 3 months old, so they asked me again.
At the time of IA, they asked me to update the PCC which was older and the rest of them were fine. So in your case under the new rules, if you guys are required to submit all PCC with the application, then you are OK, if along the time of process, these PCC gets older than 3 months, they will not ask again because they asked you to submit and you submitted it less than 3 months old PCC at that time.
Now since I have submitted my PCC, and if my final decision takes more than 6 months. I will (or may) not be required to submit the new PCC
