Until we receive our letters, we don't know a lot of that information. When I lost the last two years, the letter listed my score, number of applicants, number of winners, etc.
So far, all I have is one email from the graduate awards office telling me that I won. The email lists no other information, and the person who sent it said all the details would be in the SSHRC letter.
Also, for those curious, the email from my school does not state to keep the information secret. I gather that my department knew at the same time that I knew, as they were cc'ed in the email.
If the email had said to keep quiet I would have.
