The Special Emergency Response Team (SERT) (French: Groupe spécial d'intervention d'urgence, GSIU) was an elite police tactical unit of the Royal Canadian Mounted Police (RCMP). The SERT was formed in 1986 to provide a tactical capability to respond to major terrorist incidents throughout Canada. The unit was disbanded in 1993 when responsibility for counter terrorist response transferred from the RCMP to the Canadian Armed Forces (CAF).
