May 23, 2013 A Federal Court judge finds fraud was a factor in the robocalls, but says it is not enough to overturn the election results.
April 24, 2014 The commissioner of Canada elections reports his office received 40,000 communications from Canadians about robocalls, although 96 per cent expressed concerns about robocalls without making any specific references to such calls. The report says the number of calls spiked dramatically as more media stories on robocalls appeared.
