My application was recieved in Ottawa on the 25th of May. Still Nothing on ECAS - probably haven't started processing it yet?
I'm on the same boat, the app received on May 8th, and still nothing shows up on ECAS nor AOR.
Let's wait as it looks like it's not just few of us.
What I imagine is that as the deadline gets closer, a lot of people sent the application around that period of time (around early May till the deadline), and they got overloaded with full of applications.
The applications sent earlier like as soon as they received the invitation (not quite sure how they prepared all those things in advance without knowing whether they will be selected or not, but thumbs up on those who were well prepared..) look like that they are going through the Sponsor Approval.
And based on the trends from 2017 as well, it looks like earlier you applied, the shorter time that it took to receive AOR and processing.
Closer to the deadline, longer time it took for receiving AOR.
