Immigration, Refugee and Citizenship Canada (IRCC) invited only those Express Entry Candidates who held a nomination under the Provincial Nominee Program (PNP). Eventually, candidates get 600 CRS points with PNP. These points are automatically added to their base Comprehensive Ranking System (CRS) score.
The minimum CRS score required for the latest draw was 741 with a tie-break rule. The tie-break rules imply that IRCC used a timestamp.
