Nova Scotia's Provincial Nominee Program (PNP) doesn’t have a strict age limit for applicants, but they usually prefer candidates aged between 21 and 55. Age does play a big role in the Express Entry Comprehensive Ranking System (CRS), giving the most points to those who are 20 to 29 years old. For entrepreneur streams, being younger might be an advantage since it shows more potential for business growth. Still, older applicants who have solid work experience, good language skills, or a job offer can also qualify. Each stream has its own rules, so it's important to look at age along with other eligibility factors.
