I think they would send invitations before end of this year. So the people who are not selected, will be able to apply in the next year again or the date of next year PGP opening will be delayed until the current one results are announced.
Well it's all guess work.
I am just basing on past experience and also the work culture here in Canada.
Usually very little non essential work or projects get done in December. People take leave. Go on holidays. Departments are short handed. That kind of thing.
If they send out the ITAs in December and they aren't ready to start processing them, their processing times are going to appear LONGER when they start receiving them in December. So why would they sabotage their KPIs?
So my guess is the invitations will be sent out in mid Jan 2021 when everyone is past the Xmas/New Year holidays and is back to work.
Also unlikely the the next round of PGP EOI will open before the ITAs for the current draw are sent out. So expect the EOI for 2021 to be sometime in April or May 2021.
All just guesses on my part.
