@The1 @pillowcaserutabaga + anyone else who is wondering.. I just got a reply to my question on CGS-D vs. Doctoral Fellowship- it essentially just acknowledged my acceptance of the Doctoral instead of the CGS-D since I am at a foreign institution and said someone would reply later to other questions I had. It seems like they just included acceptance of one in the other? I did get a separate document with a notice of results specifically labelled as SSHRC Doctoral Fellowship, too. And then they just notified me that an updated notice would be added to my account 'shortly'. I hope that helps!
I am also the same- at an American institution, applied directly to SSHRC, and have multiple documents that are labelled differently (CGS-D vs Doctoral). I emailed last night when I received the results email, so I can update if I happen to hear back first about it.
