I want to add few more things here:
Quebec has more general way to immigrate. PNP is replaced by CSQ – Québec Selection Certificate. Being a foreign student, you first have to apply for a CSQ from Quebec and then apply for PR from Federal. CSQ is point-based selection system.
Check: http://www.immigration-quebec.gouv.qc.ca/en/immigrate-settle/students/stay-quebec/index.html
