SSHRC letters have not been sent yet. SSHRC's twitter account says that the letters will be mailed in late April.
Based on the comments I read here, I'm now pretty sure that I have no chance. Poor undergrad GPA (now in PhD program), no research assistantships, one peer-reviewed publication, one article submitted to publication, one national conference, two international conferences (in one of them I received an Honourable Mention for a paper I submitted to the conference's Graduate Paper Award), not a whole lot in terms of scholarships, save for a Graduate Fellowship and a Special Graduate Entrance Scholarship, plus a few minor awards such as travel grants. Sigh... Sigh indeed.
