I was one of the people who had the issue with CGS-D awards in the United States. I received the following from someone who had the problem last year. With their permission, I share it here:
" Yes, as the application directly to SSHRC (and I assume the other agencies) automatically is sent to the CGS-D and Doctoral Fellowship committees, I received results for both. The CGS-D is only able to be held at a Canadian institution, whereas the Doctoral Fellowship is anywhere. So the way my results were delivered ended up with an offer for the CGS-D (which I had to decline) and an offer for a Doctoral Fellowship (which I accepted and now hold in the USA). So, you likely have results from both and chances are that if you were accepted for a CGS-D then you did well with the Doctoral Fellowship, though I am sure there are different circumstances for both.
As I recall, my CGS-D results were in a file with the term "Results_Letter" in the name, whereas my Doctoral Fellowship results had "Notice_Decision" in the name. I can't recall whether there was any delay between getting these, but I downloaded them at essentially the same time so I wouldn't think they were too far apart.
I hope this helps, but feel free to message me back if you have more questions. Also, congratulations on the CGS-D! It is a great achievement, even if we need to enter it as 'declined' on our CVs (LOL)."
