NDVO not clear on documents asked with Medicals and note on RPRF receipt

[NishiGogetter]

Hi Folks,

I received mail for medicals , but along with that mail, it says

Please send photocopies of your passport and PCC , my VO is New Delhi.

So where do I send these photocopies and original PCC?
Is it by courier to following address as mentioned in mail?
Immigration Section/ Section de l’immigration
High Commission of Canada/ Haut-Commissariat du Canada
PO Box 5209
7/8 Shantipath, Chanakyapuri
New Delhi, India/Inde 110021

Further more, they also asked me to pay RPRF fees, which I paid, but on the receipt, it says, Please keep one copy and send another copy to CIC.

Do we really need to send one receipt copy to CIC ? or it again meant sending the receipt copy to above
mentioned address along with Passport copies and PCC.

Could you please help clarify? I am not sure why CIC or VO is not explicit on such things and keep it open for interpretation..or may be I am not able to understand.

Thanks,
Nishi
