During the 2010 G20 Toronto summit , Des Rosiers uncovered a provision invoked by the provincial government which greatly expanded police powers near a security fence on the perimeter of the summit 's location . She brought this issue to the attention of the Canadian press and ensured that CCLA volunteers monitored the Toronto police for civil liberties violations during the conference . She also helped to discourage the practice of " carding " , where police stop people who are not suspected of any criminal activity , ask for their identification and record that information for later review
