Read the link in my above post. If you have a relative or friend living in Canada it would just cost you $5. If not then order through websites. These days everything can be done by email if you have a relative in Canada.
I give you a brief idea.
First fill this form, your (friend) requester will sign it.

then fill this consent form and sign yourself

If you want to pay by credit card go to section C of the IMM5563E form and pay the fees through the link given there.
Ask your friend to provide his Canadian passport /PR card and his recent bill / bank statement as a proof that he is currently living in Canada.
Scan everything and ask him to send everything by email to
atip-aiprp @ cic.gc.ca
Thanks
