As I see this program will work as follows.
1) The community will discuss with local business about what NOCs are in demand and designate such businesses
2) Applicants will need to contact the said businesses offering their services/skills
3) Some interviews will be conducted via Skype maybe
4) If successful the business will tell the community to issue some recommendation letter
5) applicant will gather all supporting documents and send it to the community
6) the community will nominate the applicant for PR
But that is just my guess.
It should be similar to Newfoundland and Labrador PNP, where they have a list of designated employers and NOCs requested by each employer so you do not waste time contacting all of them one by one, like I did with employers in New Brunswick and Prince Edward Island who just listed the companies without listing relevant NOCs.
Let's just wait a couple of weeks before 4 communities start their application process.
