The department was created to have a single entity with responsibility for ensuring public safety in Canada and is a direct result of lessons learned from the September 11 attacks on the United States in 2001 . The department is in many ways similar to the U.S. Department of Homeland Security , though it does not cover the protection of maritime sovereignty ( this is covered by the Canadian Forces , Transport Canada , and Fisheries and Oceans Canada )
