Integrated Security Unit

Integrated Security Unit (ISU) (French: Groupe intégré de la sécurité - GIS) is a joint-services infrastructure security unit created to secure major events in Canada. This administrative and operational entity was first created by the Royal Canadian Mounted Police (RCMP) in 2003.

In 2003, the RCMP formed an ISU for the 2010 Winter Olympics and for the 2010 Winter Paralympics in Vancouver. Subsequently, another ISU was formed for the 2009 World Police and Fire Games. In 2010, the RCMP formed an ISU to coordinate security planning and operations for the 36th G8 summit in Huntsville and the 2010 G-20 Toronto summit.
