Ottawa announces tougher rules for Canada's spy agency

Torture, detention and serious destruction of property that would endanger a life are being added to the list of things Canada's spy agency cannot do when disrupting terror plots.

The legislation introduced this week retains certain powers for the Canadian Security Intelligence Service, but the Liberal government says various amendments will provide safeguards and ensure public confidence.

The Liberal legislation requires C-SIS to seek a warrant for any threat reduction measure that would limit a right or freedom protected by the Charter of Rights and Freedoms, and clarifies that a warrant can be issued only if a judge is satisfied the measure complies with the charter.

Among the things C-SIS can do to derail a threat include destroying equipment, forging documents, diverting a financial transaction, interfering with a person's movements and impersonating someone in order to carry out such acts.
