Hi nikkit, First of all, congrats on receiving MR & RPRF. This is what you could do
1) Pay the RPRF
2) Print the receipt. Fill all the details in the receipt and scan it.
3) Send the receipt to the CPP Cost Recovery email address (CPPO-Cost-Recovery @ cic.gc.ca)
4) For biodata file, it is an .htm file, you can open it in MS Word, enter the details, print it and scan it or save as PDF.
5) The biodata & RPRF receipt can then be sent in an email to ottpilot-immigration @ cic.gc.cal.
Hope this helps.
