For newbies:
NS Demand program will not require job offers (although that would make your life a lot easier) to make you eligible, as can be seen in their application guidelines.
Quote from there:
"There are two categories under the Nova Scotia Demand: Express Entry stream:
Category 1: Arranged employment in Nova Scotia You have a permanent full-time job offer (in NOC 2011 Skill Type 0, Skill Level A or B) from a Nova Scotia employer. The job offer must meet the arranged employment requirements described in this guide.
Category 2:
Paid Work Experience in an Opportunity Occupation You have at least one year of continuous full-time (or 1,560 hours or more) or an equal amount in part-time paid work experience in the last five years in one of the opportunity occupations listed in Appendix 1"
Their application guidelines is so self explanatory that it is impossible for one to miss information regarding what documents need to be sent as ORIGINALS or COPIES.
But, in order to make life easier, here's the information asked:
When preparing your application package for submission to NSOI include:
original NSNP forms and documents
copies of supporting document
Everything that isn't a NSNP form must be sent as a COPY
Simple as that.
I don't mean to be harsh or a smartass here but, come on people, go after your own information prior to asking the same questions over and over again. Everything there is to know about the process is already online. All you have to do is read it for yourself.
