The Provincial Nominee Program (PNP) allows Canadian provinces/territories to nominate candidates who wish to immigrate to Canada and are interested in living in a particular province. Canada has 13 provinces and with exceptions of Northern Canada territory of Nunavut  and Quebec, each province has it’s own immigration program:

Each of the above PNP has at least one immigration stream that is aligned with the federal Express Entry immigration selection system and these Express Entry-aligned streams are known as enhanced nominations. The enhanced PNP award applicants an additional 600 CRS points.

The second way to obtain permanent residence through the PNP is under a base stream. Under this stream, the applicant applies to a PNP stream directly and once a provincial nomination is obtained, the federal government will process the permanent residence application.
