CPP-D request more info question

Hi all,
I applied to CPP-D in March. They have now sent a letter asking for clarification of income I rec’d from my Employer which is really just my LTD from the Insurance company but it was issued through the Employer.
My question is since they are not asking for any medical info does it mean they have decided that part already and are just working out the financials? Hope to get some insightful responses soon.

I don’t think any conclusions can be drawn, it might just be a coincidence that they noticed while reviewing your file or they might be trying to figure out when you actually stopped working…
