Super helpful @abhishek !CIC has never revealed the target number of ITAs they will issue in a year. The targets set are for the number of immigrants they plan to have in each year.
Below are the targets for 2017 under each of the categories:
FSW+FST+CEC = 71,700
PNP = 51,000
1 ITA does not mean 1 PR.
In case primary applicant + spouse is applying, 1 ITA = 2 PRs
Also, there are those who decline ITAs and those who get refused after applying, which means not all ITAs are converted to PRs.
So we can never calculate the exact number of ITAs CIC is planning to issue.
Therefore 51k ITA does not mean the 70K target quota rapidly filling up!
