Police organizations across the country co-operated to spy on community organizations and activists in what the RCMP [Royal Canadian Mounted Police] called one of the largest domestic intelligence operations in Canadian history, documents reveal. Information about the extensive police surveillance in advance of last year's G8 and G20 meetings in southern Ontario comes from evidence presented in the case of 17 people accused of orchestrating street turmoil during the summits. Two undercover police officers ... spent 18 months infiltrating southern Ontario community groups ahead of the June 26-27, 2010, gathering of world leaders. They were part of a much larger so-called joint intelligence group (JIG) operation [which] employed more than 500 people at its peak. The 2010 G8 summit in Huntsville ... will likely be subject to actions taken by criminal extremists motivated by a variety of radical ideologies," reads a JIG report. "The important commonality is that these ideologies ... place these individuals and/or organizations at odds with the status quo and the current distribution of power in society." The RCMP-led intelligence team made a series of presentations to private-sector corporations, including one to "energy sector stakeholders" in November 2011. Other corporations that received intelligence from police included Canada's major banks, telecom firms, airlines, downtown property companies and other businesses seen to be vulnerable to the effects of summit protests.
