Maher Arar, a Canadian who was rendered to Syria for years of brutal torture on the basis of bad information from Canada's intelligence agencies, writes in Prism about the revelation that Canadian public safety minister Vic Toews has given Canadian intelligence agencies and police the green light to use information derived from torture in their work. Arar cites examples of rendition and torture based on the "Hollywood fantasy that underlines the 'ticking bomb' scenario that minister Toews was apparently contemplating when he wrote this directive."
What makes this direction even more alarming is that the fat annual budgets devoted to enhancing national security have not been balanced by a similar increase in oversight. In fact, the government chose to ignore the most important recommendation of Justice O'Connor which is to establish a credible oversight agency that has the required powers to monitor and investigate the activities of the RCMP and those of other agencies involved in the gathering and dissemination of national security information. Unlike the powerless Commission for Public Complaints Against the RCMP (CPC) or the Security Intelligence Review Committee (SIRC) this agency would also be granted subpoena power to compel all agencies to produce the required documents.
Coming back to the directive one can only cite two examples here which I believe are sufficient to illustrate the hollowness of the argument presented in the directive. The first relates to the invasion of Iraq which we now know was based on false intelligence (see this video) that was extracted from Ibn al-Shaykh al-Libi while he was being tortured in Egypt. Al-Libi was later found dead inside his prison cell. Some human rights activists believe the Gaddafi regime liquidated him three years after he was rendered to Libya by the CIA.
