This is from my personal experience and knowledge.
You can actually get the PCC from the asst commissioners office in India. You will need the parents or spouse to apply on your behalf. I got it done for my spouse at the commissioners office while my spouse's PCC applied at CGI is still in process.
I am yet to see the PCC report as to what is written on it (usually passport number of applicant appears on the report).
As far as CIC is concerned I believe they need a PCC from your country's government. I think I will have to wait and see.
