Then why'd they specify that in here?IRCC has said dont pay using the payment portal, I suspect the payment will be part of the application, the application will not allow you to attach a previous receipt and proceed you will need to pay on the day. Sort of like any ecommerce website does. The payment in the portal could be there for those who need to apply on paper i.e with disabilities.
"For some of our online permanent residence applications, you can’t pay within the application. Follow the steps on this on this page to pay."
"
Affected applications
- Temporary resident to permanent resident pathway (TR to PR pathway)"
Literally, IRCC? What's up with you?
