To an extent I disagree. You must realise almost all PNP stream of this nature has no charges until you are nominated and you are filing forms with CIC which to me its economically efficient.
This is also better than so many similar EOI which must require a visit. It means if NSPNP has no issues, your nomination can be issued without interview within one to three months.
Some province EOI approval alone takes one to three months. After you visit, nomination takes a month to three.
Its a skilled bound stream, and I expect something faster.
