What I think, CIC has a good relationship with WES and other evaluation company. They represent Canada and CIC shall try to upheld the image. So, an e-mail from WES should carry a great value. Note that WES report contains your address, DoB, and off course name. They might in advance give some entry on the basis of this information temporarily. So, when your application will be processed, those information will pop up.
From your part, I suggest you to call CIC directly and explain it. They will certainly be able to give you correct feedback.
