can somebody please tell email address of chc to send docs voluntarily
It would be better to send them documents via TCS / Registered Post instead of E-mail. Anyways, the email address for General inquiry is
islamabad-im-enquiry@international.gc.ca
And for case specific inquiry, you can use following link
https://dmp-portal.cic.gc.ca/cicemail/intro-eng.aspx?mission=islamabad
For TCS / Regular mail, the address is
The Canadian High Commission
Immigration Section
P.O. Box 1042
Islamabad, Pakistan
