Buddy i am may applicant and i am same as you still waiting for the test...i am from missisauga office...I requested my ATIP on August 18, it takes 31 calendar days. So hopefully have an answer back by Sept 18th.
I don't know why it is taking so long for April applicants while June applicants are moving much quicker. I don't believe they work with first-come-first-serve basis.
