CIC will send you only 1 mail for AOR, PRPR is in 2 ways, u can pay it before sending your application and put the reciecpt with your application, the advantage of doing this is to make your application faster, 2 u can pay it later during medical stage, so its in 2 ways, but i will advice u if u have money u can pay both application fee and right to permanent residence fee at once, but since you have already sent ur applicaiton, u will pay your right to permanent residence fee during or after medicals, u supose send police report with your application at first, they will ask you after medicals or before
