As we can see CIC's annual target for 2018 was to issue 74,900 ITAs only, anyhow it ended up issuing 89,800 ITAs in total, which is almost 15000 more than the initial target.
So, based on that fact we can assume this year's target to be around
81400 + 15000 = 96400.
Which seems highly likely and totaly legit! We will surely witness an increase in the ITAs during the second half of the year. Only then the trend of 450s would be reduced extensively.
