Security for international events involves federal government support when Canada hosts major international gatherings like G7/G20 summits, royal visits, or international sporting events. The federal government, through the RCMP and sometimes military forces, provides security beyond what host municipalities can deliver. Events like the G20 summit in Toronto (2010) or recent G7 summits required massive security operations. While the federal government leads security planning and provides resources, host municipalities still bear impacts: disrupted traffic, business impacts, and sometimes costs for local police support. Agreements between governments address responsibilities and cost-sharing for these exceptional events.
