An Integrated Safety and Security Group (ISSG) (), formerly known as an Integrated Security Unit (ISU) is a unified and coordinated task force comprising multiple law enforcement agencies in Canada. It is responsible for coordinating the safety and security for major national and international events, including the G7 Summit and the Olympics. This administrative and operational entity was first created by the Royal Canadian Mounted Police (RCMP) in 2003.
In 2003, the RCMP formed an ISSG for the 2010 Winter Olympics and for the 2010 Winter Paralympics in Vancouver. Subsequently, another ISSG was formed for the 2009 World Police and Fire Games. In 2010, the RCMP formed an ISSG to coordinate security planning and operations for the 36th G8 Summit in Huntsville (Ontario) and the 2010 G20 Summit in Toronto (Ontario). In 2015, an ISSG was activated for the 2015 Pan American Games and 2015 Parapan American Games held in Ontario. In 2018, the RCMP formed an ISSG to support the G7 Summit in La Malbaie, Quebec. Finally, in 2024, an ISSG has been created to lead safety and security efforts to the 2025 G7 Summit, to be held in Kananaskis, Alberta.
