International events are major global gatherings that Canada hosts, requiring substantial federal support for host cities. Events like the Olympics, FIFA World Cup, G7/G20 summits, and World Expos bring global attention but impose enormous costs on municipal infrastructure and services. The federal government provides funding for security, transportation upgrades, and venue construction, recognizing that host cities cannot bear these costs alone. Federal involvement includes diplomatic coordination, security planning through RCMP, and immigration processing for visitors. These events create economic benefits and showcase Canadian cities internationally, but require careful planning to manage costs and legacy impacts.
