I learnt from your previous post that you have paid RPRF before.If it is true,didnt you send it across with your application?If yes,then send the scan copy to Accra and write them a note that you have already paid it before and included it in the application.The reason being that they will tell you to send it to CPC mississauga.So you need to let them know you have done that in other not to delay you.
In-case you just paid newly,send the scan copy/fax to CPC mississauga through their mail/fax number and later attach the receipt with a note to Accra.You should be fine Osun!
