To not have to pay it later or create some sort of delay where IRCC requests you to pay it and it takes them 30 days to review records and determine that you did.
Cool. Thanks guys. I don't want to draw out the process more than I need to. Just noticed I have to get a new PCC as mine *just* expired and I'm expecting an invite tomorrow. UGH! Luckily it will only take a couple of weeks.
