I don't have the answer for that, but I know where I can get it. I've been speaking to a group of young entrepreneurs who work out of the Ryerson legal innovation centre in Toronto, who have designed an app that tries to help people streamline and manage better the costs of doing a pardon application. It's called ParDONE.
Through my association with them, they've done a lot of the research about the disparity across the board in the application for pardons.
