The Government of Canada introduced Securing an Open Society: Canada’s National Security Policy (NSP), in April 2004. All levels of government must work together to prevent and respond to the threat of terrorism.
The National Security Policy included measures to address terrorist threats. One such measure was the creation of the Integrated Threat Assessment Centre (ITAC), which entered into operation on October 15, 2004.
In June 2011, ITAC was renamed the Integrated Terrorism Assessment Centre in order to renew its focus on the terrorist threats to Canadians and Canadian interests.
