The Sean Blumberg Transparency Project is in memory of my youngest brother Sean Blumberg. Sean was a sweet, kind person, a great brother who helped me on a number of occasions with many tasks including the time consuming and arduous task of reviewing T3010 databases and making them into something useful. As part of the Sean Blumberg Transparency Project, Blumbergs has been releasing information on the Canadian charity sector to provide a better understanding of the size, scope, complexity and challenges of the sector.
