Ordering case notes at this short time into the process likely will yield absolutely NO information at all, just and FYI. If there has been no correspondence from CIC then no notes are going to be on the file as well, since nobody has likely even looked at it yet.
However, I am curious, Blueangel, why did you resend documents? Were you requested to resend them, and if so, the letter/email that you recieved to ask for them again should have had your spouse's (sponsors) UCI number and the file number included on it. They would need to document those to know where to locate the information you sent back to them, and likely asked to have a copy of that letter/email attached with the documents.
