Employer driven stream, and many other Job offer based PNP program nominates a candidate because a local company gives a foreigner a job. These streams are job-offer-bounded streams. Normally, the province will give them a work permit letter so they can apply for a work permit and start working ASAP while PR application in process.
Technically, if you lose your job while PR application in process, CIC has the right to reject you. How they know about it is another question but it can happen, and it had happened.
