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.
