I can't say I wasn't expecting this, FW and IS streams opened twice, it makes sense the last big intake would be for the master's stream.
Some applications get rejected or applicants withdraw, those will probably be given to NOC C/D streams as additional nominations.
What I find concerning is the fact it opened and closed within minutes, this has been 2020's trend even with a high unemployment rate. If implementing this "new NOI system" takes a year to develop, it means 2021 PNP intakes are going to be even more brutal and I wouldn't be surprised if they opened and closed within 5 minutes.
Not everyone has office jobs and can afford to refresh the desktop page every 10 seconds, people are being left out and higher than usual EE scores keep more and more people trying to get into PNP.
