Hello Raj,
The quota for the three streams FSW + CEC + FST is actually 73,700 not 92,000 (http://www.cic.gc.ca/english/department/media/notices/2016-10-31.asp)
Also do not forget that not every ITA is equal to 1 immigrant. There are people who decline their invitations and there are invitations that include more than one migrant. As far as I know spouses and dependent children also eat at that quota. I think it might be safe to assume that each ITA is the equivalent of 1.5 immigrants. (I don't think we have enough evidence to make a very educated guess on the actual number of ITA vs PRs issued). The only data that I see that testifies to something similar is from the year end report of 2015: http://www.cic.gc.ca/english/resources/reports/ee-year-end-2015.asp
Therefore:
For FSW+CEC+FST the number of ITA per month should be 73,700/(12*1.5) = 4094
For PNP the number of ITA per month should be 30600/(12*1.5) = 1700
So I would expect the number of draws to be twice a month with roughly 2900 ITA.
I think this ramp up is temporary in order to catch up on lost time. They were working hard at the last half of 2016 to clear pre EE backlog. I expect that the applications then required far more processing and therefore time consuming. So they are behind on their quota for 2017, but with the rate they are going I expect them to catch up pretty quickly.
I would be happy for everyone if I am wrong since Canada is great, but that's what the numbers tell me. Please let me know what you think!
