That's an extremely important question, which I expand on in the brief I submitted to you.
From a strictly statistical and scientific point of view, it's impossible to know what factors influence funding probabilities without knowing who applied. For example, to answer your questions, I wouldn't be able to tell you whether the people at the University of Toronto are more likely to receive grants than the people at UQAM. I couldn't answer you because if I don't know who applied, I can't tell you how the final list of grants came to be. If it's impossible to compare the number of people from a university who originally applied for a grant with the number of people from the same university who were eventually selected, I won't be able to tell you whether they're benefitting from a prestige effect.
