Hello dear friend,
I will give you my honest opinion regarding this comment in your post:
Technically speaking, if IELTS result is considered from date of test (which is 13-May-2017), her result is valid as of draw date (24-May-2017) and application date (may be a week later). Also I can upload her new result while submitting final application.
Look, you know CIC is very strict with their policies. Basically, untill you have your test results (and its TRF number), you cannot present anything to them as valid. And I don't think you can change the TRF after you have been given an ITA. Please, someone correct me if I'm wrong.
If I was you, I would take the safe road and wait untill I have the new TRF and present these new scores. After all, most of us here think that the draw will happen on May 31st, not on May 24th.
If you take the path you're telling us, you take the risk of CIC declining your aplication, and you will loose more time that way.
Anyway, just trying to be helpful.
