Joint Task Force Two was reportedly formed in April of 1993 following the transfer of the Emergency Prepardness Act to the Department of National Defence( DND). The Government spent $20 million Cdn. to get the unit started. The Times Colonist( June 1994), reported that JTF-2 is the successor to Joint Task Force One( JTF-1), which served during the Gulf War. Prior to 1993, counter-terrorist responsibilities were performed by the RCMP's Special Emergency Response Team.

There appears to be much confusion about Joint Task Force Two's actual role.

Joint Task Force Two now appears to be more of a free-roaming special forces unit rather than a counter-terrorist unit.
