My application was received on May 17 and still nothing from CIC. I finally was able to talk to an agent at the call center last week and got a temporary file number that starts with XF...
It seems like IRCC has slowed down a bit probably due to Summer vacations. Once the summer is over or when the school reopens, then things should get pick up a bit of momentum.
My application was received on May 10 and got my AOR on Jul 17. I haven't heard anything from IRCC or see anything on ECAS & MyCiC. I'm sure a lot of people are in the same boat as I am.
As for people having trouble linking it to MyCiC A/C, here are a few possibilities:
1) Check your parents name on their passport. If the passport does not specify first and last name, IRCC takes the whole name as "last name". For example, if John Doe is the name on the passport and it does not specify which one is first or last name, then John Doe is the last name on IRCC system.
2) Number of applicants associated with application could be different. There are two possibilities for this. One possibility is that they did not count both your spouse and child/children. The other possibility is they counted only your spouse or child. So try a few numbers with those possibilities.
3) If everything else failed, call IRCC. Once you hear the options on the phone, press 2-1-3-0 (in that order). It will get you to the live agent. They can definitely help you with linking your application to MyCiC.
I hope that helps.
