I have gone through the CIC website again ...it has not mentioned explicitly anywhere for the notarization except for translated documents.
Thanks for correction...
Can someone please also confirm, who has got the PER, and has not sent any document notarized???
Regarding submitting of marksheet debate which is going on, on CIC website it is mentioned -
" Submit the original ECA report with your application to the CIO along with proof of your completed foreign educational credential(s) (e.g. copies of your diplomas/degrees, transcripts, etc). "
